How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing: the API's title, version string, a list of auth hints (e.g. 'x402'), total path count, and x402-enabled path count, along with the tool name used ('util_openapi_summary').
Example use cases
Inspect an unfamiliar API before integrating
“I found this API at https://api.someservice.com/openapi.json — can you pull up a quick summary so I know the title, version, total number of endpoints, and what auth it requires? Give it up to 10 seconds.”
Count x402-payable routes in an agent API
“Check the OpenAPI spec at https://commerce.delx.ai/api/v1/openapi.json and tell me how many of its paths support x402 payments versus the total path count. Timeout after 8 seconds.”
Verify API version before deployment
“Before we deploy, can you fetch the OpenAPI summary from https://internal.mycompany.com/api/openapi.json and confirm the version number and title match what we expect? Use a 5-second timeout.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/openapi-summary?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a quick, structured summary of an OpenAPI specification from a URL without downloading and parsing the full document itself — especially useful for discovering x402-payment-gated paths. Prefer it over manual OpenAPI parsing when you want a lightweight, pay-per-use tool with no signup or API key required.
Side effects
- Timeout exceeded if the target URL does not respond within the specified timeout window
- Invalid or unreachable URL returns an error
- Non-OpenAPI URL may return malformed or empty result
- Payment failure if USDC balance is insufficient for the $0.001 fee
- Rate limiting or access restrictions on the target OpenAPI URL
