How this service works
Web search for AI agents, powered by Exa neural search: pass a query and receive relevant pages with title, URL, published date, author, relevance score and a text snippet as structured JSON. Pair with /web-extract for full-page content. For RAG retrieval, research, fact-finding and monitoring. Keyless, pay-per-call, cached by query. No matches returns an empty result set.
Output
A structured JSON object with a list of matching web pages, each containing: page title, URL, published date, author (if available), a relevance score, and a clean plain-text snippet of the content. Returns an empty result set if no matches are found.
Example use cases
Example prompt
“Search the web for the latest Ethereum roadmap updates and give me the most relevant pages with titles, URLs, dates, and a short snippet from each.”
Technical details
Endpoint
GEThttps://x402.ottoai.services/web-searchWhen to prefer
Use this endpoint when you need to retrieve live, current web content based on a natural language query — especially for RAG retrieval, research pipelines, fact-finding, or news monitoring. Prefer this over /web-extract when you need to discover and rank multiple relevant pages first before deciding which to read in full. Choose this over generic search APIs when you want clean structured JSON with relevance scores and snippets, not raw HTML.
Side effects
- No matching pages found — returns empty result set as a valid success response
- Query too vague or malformed — may return low-relevance results
- Upstream Exa service unavailable — may return error or timeout
- Payment not processed — 402 payment required response if USDC balance insufficient

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
