How this service works
Inspect an OpenAPI spec and return agent-readiness score, risks, recommendations, and x402 Bazaar candidates.
Output
Returns a structured report including: a numeric agent-readiness score, identified risks (e.g. missing schemas, ambiguous parameters, unsafe operations), actionable recommendations to improve agent compatibility, and a list of endpoint candidates suitable for listing on the x402 Bazaar marketplace.
Example use cases
Evaluate API readiness before agent integration
“I'm about to add AI agent support to our API. Can you analyze our OpenAPI spec and tell me if there are any compatibility issues or risks we need to fix first?”
Find monetization opportunities in existing endpoints
“We have a REST API with dozens of endpoints. Which ones would be most valuable to list on the x402 Bazaar marketplace, and what changes would make them more agent-friendly?”
Audit spec quality for autonomous consumption
“Our API is used by humans today, but we want autonomous agents to call it reliably. Can you audit our OpenAPI definition and highlight what needs improvement for agent safety and discoverability?”
Technical details
Endpoint
POSThttps://agentspec-one.vercel.app/inspect/openapiWhen to prefer
Use this endpoint when you have an OpenAPI specification and want to evaluate how well-suited it is for AI agent consumption — especially if you want to identify x402 monetization opportunities. Prefer this over the MCP inspector when the target is a REST/OpenAPI-defined API rather than an MCP tool manifest.
Side effects
- Invalid or malformed OpenAPI spec returns a parse error
- Missing required spec body returns 400 Bad Request
- Spec too large may exceed processing limits
- Payment not included or insufficient USDC triggers 402 Payment Required
- Unsupported OpenAPI version may yield incomplete analysis
