FAQ

Frequently Asked Questions

Serpent API supports four search engines: Google, Bing, Yahoo, and DuckDuckGo. Each engine provides web, news, image, and video search. Google also supports AI Overviews, Featured Snippets, and People Also Ask data. Yahoo and Bing share the same backend and support 112 countries. DuckDuckGo supports 72 regions. You can choose any engine per request using the engine parameter.
AI Ranking lets you track how AI models like ChatGPT, Claude, Gemini, and Perplexity mention and cite your brand or website. The API queries each AI model with your search term and returns citation URLs, visibility scores, and mention positions. You can query individual models or all four at once with a single API call using the AI All endpoint.
Serpent API provides YouTube and Instagram APIs. YouTube supports search, video details, channel details, and playlist data via the official YouTube Data API v3. Instagram provides profile scraping including follower count, post count, bio, profile picture, and recent posts. YouTube API calls start from $0.11/1K on the Scale tier.
Use the num parameter to request up to 100 results per query. Serpent API automatically handles pagination behind the scenes, fetching multiple pages from the search engine and combining results into a single JSON response. This works across all four search engines for web search. Each page fetch counts as part of the same API call.
Serpent API automatically refunds credits for failed searches (server errors). If a search engine is temporarily unavailable, the credit is returned to your account instantly. You only pay for successful results. All engines use retry logic before returning an error.
