How this service works
Callfount is one API for AI agents: web search, page reading, headless browser, LLM chat, image generation, OCR, X/Twitter, trends, weather, crypto, FX and onchain data. Pay per call with x402 in USDC on Base. No signup, no API keys.
Output
Returns a JSON object with an 'ok' boolean, a 'result' object containing the search results, the cost in USD, the service name ('search.serp'), and the content type. The result object contains the actual SERP data including snippets, titles, and URLs from the web search.
Example use cases
Real-time competitive research
“Search the web for the latest pricing and features of Anthropic Claude and OpenAI GPT-4o so I can compare them for our product decision.”
Breaking news lookup
“Find me the latest news about the Federal Reserve interest rate decision this week — search with deep depth so I get thorough results.”
Technical documentation discovery
“Search for 'how to configure pgvector for semantic search in PostgreSQL' and pull back a few chunks per source so I get enough detail from each page.”

Endpoint
POSThttps://eueptuys6mlvzykd4egohsivnm.srv.us/v1/s/search.serp?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs live, up-to-date web search results without pre-registering for a SERP API key. It is especially suitable for AI agents making infrequent or variable-volume searches (pay-per-call model avoids monthly subscription costs), or when operating in environments where x402/USDC micropayments on Base are already supported. Prefer this over traditional SERP APIs when you want zero-signup access to web search as part of a broader multi-capability stack.
Side effects
- Invalid or empty query returns an error response
- Insufficient USDC balance on Base causes payment failure and 402 response
- Search depth or chunks_per_source with invalid values may be ignored or cause errors
- Network timeout if the search provider is slow to respond
- Rate limiting or throttling under high load
