How this service works
One call, many sources: search Hacker News, GitHub, Stack Overflow, and Wikipedia by keyword and get back a unified, ranked result set — titles, URLs, scores/stars, and snippets — across all of them at once. The general research/search read agents make to ground answers, find code, surface discussion, and gather context. No API keys, no per-source accounts, free upstreams. Pass `sources` to narrow (hackernews,github,stackoverflow,wikipedia).
Output
Returns a JSON object with the echoed query string, total result count, list of results (each with URL, title, snippet, source label, and relevance score), and an array of sources queried.
Example use cases
Example prompt
“Search for 'vector database' across GitHub, Hacker News, Stack Overflow, and Wikipedia and give me the top 8 results per source.”
Technical details
Endpoint
GEThttps://store.agentexchange.work/web/searchWhen to prefer
Choose this endpoint when an AI agent needs cross-source search covering developer and knowledge communities (GitHub, Hacker News, Stack Overflow, Wikipedia) without setting up API keys, and when the agent can pay $0.004 USDC per call via the x402 protocol on Base. Ideal for autonomous agents that need ad-hoc search with micropayments instead of subscription credentials.
Side effects
- Missing required 'q' parameter returns 400 error
- Payment not included or insufficient USDC triggers 402 Payment Required
- Invalid source name in comma-separated 'sources' list may be ignored or cause 400
- limit value outside 1-10 range may be clamped or rejected
- Upstream source (e.g. GitHub, HN) unavailable leads to partial results or 503
