How this service works
Flatten an OpenAPI 3.x or Swagger 2.x spec into a structured list of callable endpoints - one row per operation with method, path, operationId, summary, tags, parameters (name / in / required / type), JSON-body flag, and documented response codes. Includes per-method and per-tag counts so an agent can pick what to call next without parsing the full spec. Output is sorted by path then method for stable, agent-friendly grouping. Pure CPU - deterministic, no network, no $ref dereferencing.
Output
A structured list of endpoint rows, one per API operation, each containing the HTTP method, URL path, operationId, summary, tags, parameter details (name, location, required flag, type), whether a JSON body is expected, and documented response codes.
Example use cases
Example prompt
“Can you parse this OpenAPI spec I'm pasting and give me a flat list of every endpoint — including the HTTP method, path, operationId, parameters, and response codes for each operation?”
Technical details
Endpoint
POSThttps://agent402.tools/api/openapi-extractWhen to prefer
Use this endpoint when you need to programmatically introspect an OpenAPI or Swagger specification and want a flat, tabular representation of all operations — ideal for building API catalogs, agent tool registries, or automated documentation workflows. Prefer this over manual parsing when you need parameter-level detail including types, required flags, and response codes in a single structured response.
Side effects
- Invalid or malformed OpenAPI/Swagger document returns a parse error
- Spec passed as a non-object and non-JSON string may be rejected
- Unsupported spec version (e.g. OpenAPI 1.x) may not be parsed correctly
- Very large specs may time out or exceed payload limits
- Missing required 'spec' field returns a validation error
