DeepSeek search,
ready to build with.
Use DeepSeek’s native Search API through openSERP for ranked web results, AI-generated summaries, source metadata and MCP workflows.
Native search for agents.
This integration calls DeepSeek’s standalone Search API. Retrieve up to fifty results in one request, including titles, snippets, longer summaries, dates and relevance scores when available. Summaries are generated by AI and may contain errors or omissions. Queries, including added operators, are limited to 128 Unicode characters. Full page content is fetched separately through a budgeted realtime Markdown request.
Available results
Organic destination URLs, snippets, AI-generated summaries, site names, publication dates, relevance scores and authority tiers when returned. Country-code localization, filetype guarantees and pagination are not supported.
Supported parameters
query, maxResults (1–50), language, site, exactTerms, excludeTerms; page=1
Parameter support varies by offering. The API checks capability before routing. Free queries may choose an engine and use shared cached results with automatic routing. Firehose Lite is available to free users; Advanced requires paid access, including cached results. Provider selection and fast/cheap preferences require credits. Free live searches use the daily allowance. Firehose manages its own routing.
