Desearch is a web search API built for AI agents that need fresh, cited context from the live web. One API key covers AI Search, Web Search, Extract, and X Search, so an agent can find links with snippets and highlights, get a sourced answer alongside its sources, pull clean content from any URL, or retrieve posts, profiles, replies, and trends from X. The index is built on Bittensor, where subnet 22 miners and validators crawl the web, and Desearch runs the search API on top of it, reporting more than 1.75 billion searchable pages. Results carry source URLs, relevant passages, and publication dates where available, and you can narrow web searches to specific domains or use site filters for Reddit, Hacker News, Wikipedia, and arXiv. It connects over REST, Python and JavaScript SDKs, or an MCP server, with guides for LangChain, LlamaIndex, CrewAI, and OpenClaw. Pricing is pay as you go: web search $1.00 per 1,000 searches, AI search $0.40 per 1,000 items, Extract $0.50 per 1,000 pages, and X search $0.15 per 1,000 posts, with $5 in credits for new accounts after attaching a card. It suits agent builders who want grounded, source-linked answers instead of stale model knowledge.
