How this service works
Tavily-compatible web search. POST JSON { query } — ranked results, snippets, source URLs, optional answer. $0.01 USDC on Base (Solana rail when configured). Same request/response shape as Tavily x402 POST /search.
Output
A JSON object containing the original query, an array of ranked result objects (each with URL, title, content snippet, relevance score, and optional raw content), an optional AI-generated answer string, an array of image URLs if requested, a unique request ID, response time in seconds, and optional follow-up questions.
Example use cases
Real-time competitor research
“Search the web for recent coverage of Anthropic's Claude product updates from the last 30 days — give me up to 15 ranked results with snippets and a summary answer.”
Finance news lookup for trading agent
“Find the top finance news about NVIDIA earnings this quarter, topic set to finance, up to 10 results, and include an AI answer with the key takeaways.”
Domain-scoped fact verification
“Search for information about the x402 payment protocol but only pull results from x402.org and coinbase.com — give me 5 results with full snippets so I can verify the official documentation.”
Technical details
Endpoint
POSThttps://store.agentexchange.work/searchWhen to prefer
Choose this endpoint when you need advanced-depth web search with ranked, high-quality results and optional AI-generated answers, especially when you want Tavily-compatible request/response structure with per-call micropayment pricing ($0.01 USDC) instead of a monthly subscription. Prefer it over basic search endpoints when you need topic filtering (general/news/finance), domain inclusion/exclusion controls, date range scoping, or raw page content alongside snippets.
Side effects
- Empty or malformed query returns a 400 validation error
- Payment of $0.01 USDC not fulfilled triggers a 402 Payment Required response
- Query exceeding 4000 characters is rejected
- Requested domains may yield no results if they have no indexed content
- Date range filters may return empty results if no content matches the window
- Network timeouts may occur for complex queries exceeding typical response time
