How this service works
Machine-readable settlement service
Output
Returns the matched OpenAPI operation object, including the HTTP method, path, parameters, request body schema, response schemas, and any other metadata defined for that operation in the specification.
Example use cases
Locate endpoint for agent routing
“I have an OpenAPI spec and I need to find the operation that handles creating a new order — can you search it and return the full operation definition including its path and method?”
Extract parameters before API call
“Before I call this external API, search its OpenAPI spec for the 'getCustomerById' operation so I can see exactly what parameters it requires.”
Discover authentication endpoint schema
“Search this OpenAPI document for any operation related to authentication or token generation and give me the full schema so I know what fields to send.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/openapi.search--find-openapi-operationWhen to prefer
Use this endpoint when an agent needs to programmatically discover or retrieve a specific operation from an OpenAPI/Swagger document at runtime — for example, before constructing a dynamic API call, validating an operation exists, or extracting parameter schemas for downstream use. Prefer this over manually parsing OpenAPI files or using a generic search when you need a structured, machine-readable operation definition returned quickly.
Side effects
- Operation not found — no matching endpoint in the spec returns empty or null result
- Malformed or invalid OpenAPI spec input causes parsing failure
- Ambiguous search query matches multiple operations — may return first match or error
- Missing required 'input' field returns 400 validation error
- Spec too large or complex may cause timeout
