Serpent API Documentation

Complete guide to integrating search, Maps business data, AI ranking and social data.

Getting Started

Serpent API provides programmatic access to search results from Google, Bing, Yahoo, and DuckDuckGo, plus AI ranking and social media data. It supports three categories of endpoints:

SERP Endpoints

  • Quick Search — 1 page, ~10 results. Web billing follows account state. Use /api/search Deep Search for multi-page Google results (up to 10 pages, ~100 results). "Google SERP" here means search results from Google · Bing · Yahoo · DuckDuckGo · Brave.
  • Deep Search — Up to 10 pages (~100 results) with related searches, ads, PAA, featured snippets, and AI overviews. Defaults to 5 pages.
  • News Search — News articles with sources, timestamps, and snippets
  • Image Search — Images with thumbnails, originals, dimensions, and sources
  • Video Search — Video results with titles, thumbnails, durations, and views
  • Shopping Search — Product results with titles, prices where available, merchant/store names, URLs, and thumbnails

AI Ranking Endpoints

  • Combined AI Rank — Check how AI models (Claude, ChatGPT, Gemini, Perplexity) cite your domain
  • Single Engine Rank — Query a specific LLM for citation analysis

Social Media Endpoints

  • YouTube Search — Search for videos, channels, and playlists
  • YouTube Video/Channel — Get detailed video and channel information
  • Instagram Profile — Scrape public profile data and recent posts

Google Maps Endpoints

  • Quick Place Search — up to 20 ranked places; draws from the shared 10-call free pool for new accounts
  • Deep Place Search — attempts up to 100 ranked places with truthful partial-detail status
  • Place Details — one richest-available normalized place record
  • Reviews — up to 20 public reviews per call with opaque pagination

Quick Start

  1. Create an accountSign up with your Google account (free)
  2. Generate an API key — Go to the API Keys page and create a key
  3. Make your first request — Use your API key to search
curl "https://apiserpent.com/api/search?q=hello+world" \
  -H "X-API-Key: YOUR_KEY"

You get 10 free lifetime calls, shared across every endpoint — Web Search, News, Images, Videos, Shopping, AI Rank, LinkedIn, Maps, YouTube, and Instagram.

Base URL

All API requests use the following base URL:

https://apiserpent.com

All endpoints are relative to this base. For example, the web search endpoint is:

https://apiserpent.com/api/search

Authentication

All search endpoints require an API key. You can authenticate in two ways:

Option 1: HTTP Header (Recommended)

X-API-Key: sk_live_your_api_key_here

Option 2: Query Parameter

GET /api/search?q=keyword&api_key=sk_live_your_api_key_here
Keep your API key secret. Never expose it in client-side code or public repositories. The header method is strongly preferred for security — query parameters may appear in server logs and browser history.
Credit cost: Category pricing applies by endpoint. Web from $0.60/1K calls Default, $0.06/1K calls Growth, $0.03/1K calls Scale. New accounts get 10 shared free calls on eligible endpoints. Growth pricing is locked in forever with a one-time $100 deposit (10× off); Scale with a one-time $500 deposit (20× off). See Pricing for full details.

Free Tier

Every new account receives one shared lifetime allowance of 10 free calls (no credit card required), usable across:

  • Quick Search (/api/search/quick) — all engines (Google, Bing, Yahoo, DDG, Brave) — draws from the same shared pool
  • Deep Search (/api/search) — all engines
  • Maps Quick (/api/maps/search/quick) — draws from the same shared pool
The 10-call free pool is shared across every endpoint — Web Search (Quick + Deep, any engine), News, Images, Videos, Shopping, AI Ranking, LinkedIn, Maps (Quick, Deep, Place, Reviews), and Social (YouTube + Instagram).

Deep Search

Perform a deep web search that returns up to 100 organic results with related searches, ads, People Also Ask, featured snippets, AI overviews, and more. For more than 10 results, the API automatically retrieves multiple pages. This endpoint is free-tier eligible.

GET /api/search

Parameters

ParameterTypeDescription
q required string The search query (max 2,048 characters)
num integer Number of results: 10–100 (default: 10). Automatically determines pages to retrieve. Rounded up to the nearest 10 (e.g., num=15 returns up to 20).
engine string google, bing, yahoo, ddg, or brave (default: "google")
country string Country code for localized results (default: "us"). See Country Support.
format string Response format: full or simple (default: "full"). Simple returns just position, title, and URL.
pages integer Number of result pages to retrieve: 1–10 (default: 1). Alternative to num.
freshness string Time filter: h/1h (hour), d/1d (day), 7d (week), w, m/1m, y/1y (optional)
safe string SafeSearch: off, moderate, or strict (optional)
language string 2-letter ISO language code (e.g., en, es, de, fr, ja). Restricts results to that language. Supported by Google, Yahoo, and DDG. (optional)
include_aio boolean Google Deep only. Set true to request AI Overview fields on eligible paid calls. If unavailable, aiOverview stays null and organic results still return.
pixel_position BETA boolean When true, every item in the response (organic, AI Overview, PAA, ads, featured snippet, knowledge panel, local pack, shopping, videos) gets two sibling fields: a pixel_position integer (y-coordinate in pixels from the top of the rendered desktop SERP) and a pixel_box object with the element's full bounding rectangle ({ x, y, w, h }). Supported on all four engines (Google, Yahoo, Bing, DuckDuckGo) on desktop, US locale. Paid tiers only — free-tier responses include metadata.pixelPositionUnavailable: 'free_tier'. No price increase. Full spec →
Use num or pages, not both. If you pass num=50, the API will automatically retrieve 5 pages. Each page yields ~10 results. Multi-page web billing follows account state: Growth/Scale accounts and Default accounts with at least a $10 live balance are billed one published web-search unit per request for supported page depths; low-balance Default accounts can be billed per delivered page.

Not supported on News, Images, or Videos endpoints. Full spec →

AI Ranking API — Combined

Check how AI language models cite and rank your domain or brand. This endpoint queries multiple LLMs (Claude, ChatGPT, Gemini, Perplexity) simultaneously and returns citation analysis for each.

GET /api/ai/rank

Parameters

ParameterTypeDescription
keyword required string The search keyword/topic to query. Also accepts q as an alias.
domain string Your domain to track in citations (e.g., example.com) (optional)
engines string Comma-separated list of AI engines: claude, chatgpt, gemini, perplexity (default: all four)
prompt_type string Prompt style: standard, deep, or brand (default: "standard")

Example Request

curl "https://apiserpent.com/api/ai/rank?keyword=best+seo+tools&domain=ahrefs.com&engines=claude,chatgpt" \
  -H "X-API-Key: sk_live_your_api_key"

Per-Engine Response Fields

FieldTypeDescription
target_foundbooleantrue if the requested domain (or any of its subdomains) appears in this engine's citations
target_positioninteger | null1-indexed citation position where the domain was first matched. null if not found.
target_match_typestring | null"exact" (cited domain equals domain after stripping www.), "subdomain" (a subdomain of domain was cited — e.g. docs.example.com for example.com), or null if not found.
target_matched_domainstring | nullThe actual domain that matched. Equals domain for exact matches; equals the subdomain hostname for subdomain matches.
citationsarrayList of citations returned by this engine, each with position, url, title, domain.
total_citationsintegerNumber of citations parsed.
response_textstringThe full LLM response text used to derive the citations.
latency_msintegerTime the engine took to answer, in milliseconds.

Subdomain matching is implicit — the API tries an exact match first, then falls back to a subdomain match. Use target_match_type on the client to differentiate the two when displaying ranking results.

AI Ranking endpoints require paid credits. They are not eligible for the free tier. Pricing varies by engine — see Pricing for details.

AI Ranking API — Single Engine

Query a specific AI engine for citation analysis. Available engines: claude, chatgpt, gemini, perplexity.

curl "https://apiserpent.com/api/linkedin/profile/full?username=williamhgates" \
  -H "X-API-Key: sk_live_your_api_key"
Full Profile is best-effort and returns identity, summary, full experience history, education, photo, and follower/connection counts. Depth varies by profile — it is not a guaranteed complete résumé. Priced at $4.00/1K (Growth $3.60/1K, Scale $2.80/1K) — the standard tier discounts apply.

LinkedIn Posts API

Serpent's LinkedIn API returns a person's recent public posts — content, publish date, and engagement (reactions/comments/reposts) — resolved from the person's profile URL, username, or name. This endpoint is free-eligible (shared 10-call pool).

GET /api/linkedin/posts

Parameters

ParameterTypeDescription
username string Profile vanity slug (e.g., williamhgates). Provide username, url, or name.
url string Full profile URL (e.g., https://www.linkedin.com/in/williamhgates).
name string Person's full name (e.g., Bill Gates).
limit integer Max posts to return (default: 10)

Example Request

curl "https://apiserpent.com/api/linkedin/posts?username=williamhgates" \
  -H "X-API-Key: sk_live_your_api_key"
Post retrieval is best-effort — only the person's publicly visible posts that can be resolved are returned, and depth varies by profile and by public post visibility. Priced at $1.00/1K (Growth $0.90/1K, Scale $0.70/1K).

Google Maps Quick Place Search

Returns up to 20 ranked place records. New accounts get 10 free lifetime calls shared across every endpoint — Web Search, News, Images, Videos, Shopping, AI Rank, LinkedIn, Maps, YouTube, and Instagram. The four Maps endpoints serve on https://api.apiserpent.com/api/maps/*; verify your exact query in the playground before production integration.

GET/api/maps/search/quick

Parameters

ParameterTypeDescription
q requiredstringBusiness category or place query.
locationstringText location. Do not combine with lat/lng.
lat, lngnumberPaired coordinates. Both are required when either is supplied.
countrystringTwo-letter country code (default: us).
languagestringTwo-letter language code (default: en).
zoomintegerMap zoom from 3 to 21 (default: 14).
startintegerOne of 0, 20, 40, 60, or 80.

Tested cURL

BASE_URL="${SERPENT_BASE_URL:-http://localhost:3001}"
curl --get "$BASE_URL/api/maps/search/quick" \
  -H "X-API-Key: YOUR_API_KEY" \
  --data-urlencode "q=coffee" \
  --data-urlencode "location=New York, NY" \
  --data-urlencode "country=us"

Search response

{
  "success": true,
  "type": "maps",
  "endpoint": "quick",
  "places": [{
    "rank": 1, "place_id": "...", "name": "Example Coffee",
    "website": "https://example.com", "rating": 4.6,
    "detail_status": "complete"
  }],
  "counts": { "requested": 20, "discovered": 20, "returned": 20, "fully_enriched": 19, "core_only": 1 },
  "meta": { "elapsed_ms": 27498, "partial": true }
}
Partial detail: a core_only record keeps its discovered rank and available core fields. Treat its nullable detail fields as unknown, not as confirmed absence. counts and meta.partial make the state explicit.

Google Maps Deep Place Search

Attempts positions 1–100 using the same parameters and place schema as Quick. Deep is paid from the first call.

GET/api/maps/search
curl --get "$BASE_URL/api/maps/search" \
  -H "X-API-Key: YOUR_API_KEY" \
  --data-urlencode "q=coffee" \
  --data-urlencode "location=New York, NY"

A local acceptance run on 2026-07-02 returned 97 places in 88.2 seconds: 85 complete and 12 core_only. This measurement is an example of a full-depth pass, not a production latency guarantee — real latency varies with query, country, and platform load.

Google Maps Place Details

Returns one richest-available normalized place. Provide exactly one identifier.

GET/api/maps/place
ParameterTypeDescription
place_idstringGoogle place ID.
data_idstringGoogle Maps data ID.

curl --get "$BASE_URL/api/maps/place" \
  -H "X-API-Key: YOUR_API_KEY" \
  --data-urlencode "place_id=ChIJ..."

detail_statusstringcomplete when enrichment finished, or core_only when only the ranked core record was returned within the request deadline.

Any field can be null when Google does not expose it for that place — absence is honest, never fabricated.

Google Maps Reviews

Returns up to 20 public reviews per call. Provide exactly one place identifier and reuse the returned opaque token for the next page.

GET/api/maps/reviews
ParameterTypeDescription
place_id / data_id / urlstringExactly one place identifier.

reviewerobject | nullPublic reviewer info: name, id, url, profile_photo, review_count, and local_guide boolean.

Review fields can be null when Google does not expose them for a given review. Absolute review dates are not always available; relative_date is the reliable label.

Search Engines

Serpent API supports five search engines: Google (default), Bing, Yahoo, and DuckDuckGo. Use the engine parameter on any SERP endpoint to choose.

EngineValueSupported Endpoints
Google google Web, News, Images, Videos, Shopping. Includes ads, PAA, featured snippets, optional AI overviews, and inline videos where present.
Bing bing Web, News, Images, Videos. Includes ads, PAA, and inline videos where present.
Yahoo yahoo Web, News, Images, Videos, Shopping. Includes ads, PAA, and inline videos where present.
DuckDuckGo ddg Web, News, Images, Videos. Includes ads and related searches.
Brave brave Web, News, Images, Videos. Includes related searches and Brave's AI digest (exposed as aiOverview).
Pricing is category-based. Engine choice does not change the public rate within Web, News, Images, Videos, or Shopping. Dedicated Video Search supports Google, DDG, Yahoo, Bing, and Brave. Dedicated Shopping Search supports Google and Yahoo.

Country/Region Support

Get localized search results by specifying a country code. This affects the language, regional rankings, and availability of results.

GET /api/countries

Returns a list of all supported country codes programmatically. This endpoint does not require an API key.

Example Response

{
  "success": true,
  "count": 112,
  "countries": [
    { "code": "us", "region": "us" },
    { "code": "uk", "region": "uk" },
    ...
  ]
}

Supported Countries

We support 112 countries for localized search results (gb is an alias for uk).

gb is accepted as an alias for uk — both work and return United Kingdom results.

Language Support

Restrict search results to a specific language by passing a 2-letter ISO 639-1 code to the language parameter. Supported by Google, Yahoo / Bing, and DuckDuckGo across web, news, and image search.

Tip: language filters by content language; country sets the geographic search context. Combine both for the best localization (e.g., country=de&language=de for German searches in Germany).

Response Format

All responses are JSON. Every response includes a success boolean. Search responses include engine, country, and a meta object with timing info.

Full Response (Web Search)

The default format=full response includes all available data:

{
  "success": true,
  "query": "best seo tools",
  "engine": "google",
  "country": "us",
  "pages": 5,
  "results": {
    "organic": [{ "position", "title", "url", "snippet", "displayedUrl" }],
    "relatedSearches": [{ "query": "free seo tools" }, ...],
    "ads": { "top": [], "bottom": [], "totalCount": 0 },
    "peopleAlsoAsk": [],
    "featuredSnippet": null,     // Google only
    "aiOverview": null,          // Google Deep with include_aio=true
    "richSnippets": [],
    "videos": [],               // Google, Yahoo/Bing
    "shopping": []
  },
  "metadata": {
    "totalOrganicResults": 50,
    "hasAds": false,
    "hasRelatedSearches": true,
    "hasPeopleAlsoAsk": false,
    "hasVideos": false,
    "hasShopping": false,
    "hasFeaturedSnippet": false,
    "hasAiOverview": false,
    "source": "google"
  },
  "meta": { "totalOrganic", "requestedNum", "elapsed", "timestamp" }
}
SERP features: Google web search may include featuredSnippet, optional aiOverview, and videos data. Yahoo/Bing includes peopleAlsoAsk and videos. DDG includes ads and relatedSearches. All fields are always present in the response (empty arrays/null when not available).

Simple Response

Use format=simple for a lightweight response. Available on all six search endpoints (quick search, deep web search, news, images, videos, shopping).

Important: with format=simple, the results field is a flat array of lightweight endpoint-specific items — not an object. With format=full (the default), results is an object with endpoint-specific arrays such as organic, articles, images, videos, or shopping. A safe web-search accessor is: const organic = Array.isArray(r.results) ? r.results : (r.results?.organic || []);

format only changes the response shape; it does not change endpoint pricing. To use the lower-priced quick contract, choose /api/search/quick instead of /api/search.

Web Search (/api/search)

Returns position, title, url. With pixel_position=true, each item also carries a pixel_position integer and a pixel_box object (see Pixel Position):

{
  "success": true,
  "query": "best seo tools",
  "engine": "google",
  "country": "us",
  "results": [
    { "position": 1, "title": "...", "url": "..." },
    // with pixel_position=true:
    {
      "position": 2,
      "title": "...",
      "url": "...",
      "pixel_position": 847,
      "pixel_box": { "x": 180, "y": 847, "w": 600, "h": 96 }
    }
  ],
  "meta": { "total": 50, "requestedNum": 50, "elapsed": "2450ms" }
}

News Search (/api/news)

Returns position, title, url, source:

{
  "success": true,
  "query": "artificial intelligence",
  "type": "news",
  "engine": "google",
  "country": "us",
  "results": [
    { "position": 1, "title": "...", "url": "...", "source": "..." }
  ],
  "meta": { "total": 20, "elapsed": "1800ms" }
}

Image Search (/api/images)

Returns position, title, original, thumbnail:

{
  "success": true,
  "query": "mountain landscape",
  "type": "images",
  "engine": "google",
  "country": "us",
  "results": [
    { "position": 1, "title": "...", "original": "...", "thumbnail": "..." }
  ],
  "meta": { "total": 50, "elapsed": "1200ms" }
}

Error Codes

All error responses include an error field with a human-readable message. Some errors also include a message field with additional details.

CodeMeaningDescription
400 Bad Request Missing or invalid parameters (e.g., no q param, invalid engine)
400 num must be a positive integer The num parameter must be a positive integer (1 or greater). Values like 0, -1, or non-numeric strings are rejected.
401 Unauthorized Invalid or missing API key
402 Payment Required Insufficient credits. Free searches exhausted and no credit balance.
404 Not Found Endpoint does not exist
429 Too Many Requests Rate limit exceeded. See Rate Limits for tier-specific limits.
500 Server Error Internal error — try again or contact support
502 Bad Gateway We are experiencing unusually high request volume. Please try again later.

Error Response Example

// 400 Bad Request
{ "error": "Query parameter \"q\" is required" }

// 401 Unauthorized
{ "error": "Unauthorized", "message": "API key required. Provide X-API-Key header or api_key query parameter." }

// 402 Payment Required
{ "error": "Payment Required", "message": "Insufficient credits", "credits": 0, "costPerSearch": 0.0001 }

// 503 Service Unavailable
{ "success": false, "error": "Temporarily unavailable", "message": "Please try again later." }

Rate Limits

Rate limits are per account (shared across all your API keys) and scale with your current credit balance. Every account gets four ceilings — max concurrent in-flight requests, and max requests per minute, per hour, and per day. Higher brackets also get higher priority in the processing queue under load.

BracketConcurrentPer minutePer hourPer dayQueue priority
Free — no deposit110100500Lowest
Default — balance < $1003–2020–100200–1,0001,000–unlimited*Standard
Growth — balance $100–$49910–100100–1,0001,000–10,0008,000–unlimited*High
Scale — balance $500+100–1,000500–5,0005,000–50,00030,000–unlimited*Highest
Published figures are standard "up to" allocations, not guaranteed floors — actual throughput may be lower when the platform is under heavy load. Each range shows the standard allocation at your balance to the high end available on request: * higher custom allocations are provided on requestcontact us for custom limits. For Default accounts, requests above 1,000 calls/day are served on a global shared pool (best effort, not a guaranteed floor). The per-minute, per-hour and per-day windows reset on fixed UTC boundaries (top of each minute/hour, and 00:00 UTC for the day). A 429 response names which window you hit and includes a Retry-After header — back off and retry. Your bracket follows your live credit balance — topping up raises your limits immediately; spending down can lower them. Pricing tiers are a separate dimension: they're locked in by a one-time deposit and don't move with your balance.

Response Timing

Response time varies by endpoint, engine, requested depth, target country, and current platform load. The Playground shows live elapsed time for individual requests.

Need higher rate limits?

Published limits are standard defaults. If your workload needs more — higher concurrency, /min, /hour, or /day allocations — contact us for a reviewed custom-limit allocation.
