How this service works
Paid APIs with no signup. USDC on Base via x402.
Output
A JSON object containing the original query string, the source attribution ('exa.ai'), the fetch timestamp, and an array of results — each with a URL, title, text snippet, and publication date — plus the price charged in USD for the call.
Example use cases
Real-time news lookup for agent
“Search for the latest news about the Ethereum Dencun upgrade and return the top articles with their titles and URLs — I want results from the past week.”
Research assistant for niche topics
“Find me recent web pages about using USDC for micropayments in AI agents — I need the title, URL, and a text snippet for each result.”
Competitive intelligence gathering
“Search the web for 'Coinbase x402 protocol announcements' and pull back the most recent articles so I can summarize what's happening in that space.”
Technical details
Endpoint
GEThttps://keyless-theta.vercel.app/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need ad-hoc web search with no API key registration, no subscription, and want to pay only for what you use via USDC micropayments on Base. It is ideal for AI agents that need occasional or burst web lookups without committing to a search API plan, and for developers building x402-compatible workflows who want a ready-made search primitive powered by Exa.ai's neural search index.
Side effects
- Invalid or empty query string returns no results or an error
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the request
- Rate limiting or upstream Exa.ai outage causes a failed or delayed response
- Queries returning no indexed results yield an empty results array
- Malformed request missing the query parameter returns a 400-level error
