How this service works
Web search for agents. POST a JSON body with a "query" string and an optional "limit" (1-20); returns ranked results, each with a title, url and text snippet. Keyword and semantic matching, no API key required, billed per call at $0.001 USDC on Base.
Output
A ranked list of up to 20 web results, each containing a page title, URL, and a short text snippet summarizing the relevant content from that page.
Example use cases
Real-time fact lookup for agent
“Search the web for 'current interest rate Federal Reserve 2025' and show me the top 5 results so I can get the latest figures.”
Research gathering for report writing
“Find me up to 15 web pages about 'climate change impact on coral reefs' — I need titles, links, and summaries to pull sources for a research report.”
Competitive intelligence search
“Search the web for 'Notion AI pricing and features 2025' and return the top 8 results so I can compare what competitors are offering.”
Technical details
Endpoint
POSThttps://x402-echo-service.onrender.com/searchWhen to prefer
Choose this endpoint when an AI agent needs to perform open web search without managing API keys or OAuth flows, and when the x402 micropayment model ($0.001 USDC per call) is acceptable. Ideal for agents that need to ground responses in current web content, retrieve URLs and snippets for a topic, or supplement knowledge with live internet results. Less suitable when you need structured data from a specific site, real-time news feeds, or image/video search results.
Side effects
- Query string missing or empty — returns 400 validation error
- Limit out of range (below 1 or above 20) — returns 400 validation error
- Query exceeds 512 characters — returns 400 validation error
- Payment not completed or insufficient USDC balance — returns 402 Payment Required
- Service temporarily unavailable (Render cold start or downtime) — returns 503 or timeout
- No results found for very obscure or malformed query — returns empty results array
