AgentIndex x402 Web Search is a paid API for AI agents from x402.agentindex.world, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-27).
Pay-per-call web search endpoint that runs one or more queries and returns ranked results with optional page extracts and synthesized summaries.
Jev-routed web search: each query goes to the best specialised source (code, facts, news, prices), results ranked by relevance. 28/30 test queries answered. Up to 10 results per query, each with title, URL, snippet, short extract and publish date. Up to 5 queries per call, merged and de-duplicated. No account, no API key. Try GET /search/sample. Part of the AgentIndex content kit (pdf, web-read, extract, summarize, detect-language) - see GET /capabilities.
A JSON object containing the original query and an array of results, each with a URL, title, optional publication date, and (if requested) a cleaned page extract stripped of navigation and boilerplate. When summarize is enabled, a short synthesized answer string is also included. Results from multi-query calls are merged and deduplicated by URL.
GEThttps://x402.agentindex.world/search?utm_source=zero.xyzChoose this endpoint when your agent needs live web search results not available in its training data, especially when you want to run up to 5 related queries in a single pay-per-call request and deduplicate by URL. The optional extract and summarize flags make it particularly useful when you need not just links but actual page content and a synthesized answer in one round-trip. Prefer it over generic search APIs when operating in an x402 pay-per-call agent infrastructure context.
