Neurobird Search API

Web search API for AI agents and developers, from $2 per 1,000 searches. One call runs the whole retrieval path: fan out across many search engines, fuse the rankings with reciprocal rank fusion, fetch and extract the top pages, rank the passages inside them, and optionally write an answer whose every supporting quote is checked back against its source text. **Compatible with Tavily.** The request and response shapes match, so an existing Tavily client switches by changing the base URL to `https://search.neurobird.com` and the bearer token to a Neurobird key. **Getting a key:** `POST /keys` with no authentication returns a key carrying 1,000 free credits a month. There is no signup form, no email and no card. **Credits:** basic or standard search 1, advanced search 2, grounded answer +1, structured extraction +1, `/extract` 1 per page. **Paying:** prepaid credit packs in crypto (`POST /billing/crypto/checkout`), or per call with x402 and no account at all. `GET /payments` describes every option. **MCP:** a hosted Model Context Protocol server is available at `POST /mcp` over streamable HTTP, exposing `web_search` and `extract_url`.
