What you get

Summary plus one row per operation:

{
  "spec_type": "openapi", "spec_version": "3.0.4",
  "title": "Swagger Petstore", "grade": "A", "operations": 19,
  "undocumented_operations": 0, "security_schemes": ["petstore_auth", "api_key"],
  "unsecured_operations": 10,
  "fixes": ["10 operation(s) have no security applied."]
}

{ "method": "POST", "path": "/pet", "operationId": "addPet",
  "summary": "Add a new pet to the store", "problems": [] }

Use cases

API teams: run in CI against your published spec; fail the build when documentation or security coverage regresses.
Agents and integrators evaluating an API: know before you build whether the contract is complete, secured, and code-gen friendly.
Consultants: an instant, evidence-backed quality read on a client's API surface.

Honesty notes

Validates structure and hygiene against the OpenAPI/Swagger shape; it is a completeness and quality audit, not a live conformance test against a running server.
YAML and JSON specs are both accepted; a document that is neither, or has no openapi/swagger field, is rejected free.
Fetching a spec is one polite GET; billing is per completed audit.

Built by 1450 Enterprises, alongside the MCP Server Probe and MCP Server Diff — the same "inventory a machine interface" idea, applied to REST.

OpenAPI Security Auditor

q_services/openapi-security-auditor

Audit OpenAPI and Swagger specifications for unsecured operations, unsafe server URLs, weak auth schemes and missing security responses.

Q Services

OpenAPI Quality Auditor API

merlin-hermes/openapi-quality-auditor-api

Deterministically audits supplied OpenAPI or Swagger text for endpoint inventory, documentation gaps, security-declaration coverage, and mutating-operation flags without calling any described API operation.

OpenAPI Spec Drift Detector

stellar_ballet_0bu/openapi-spec-drift-detector

Compare two OpenAPI 3.0/3.1 specs (JSON or YAML) and emit per-endpoint / per-operation / per-schema change rows with a `breaking` flag. Pairs with the api-response-delta-monitor.

OpenAPI to LLM Tools & Function Calling

awesome_highboy/openapi-llm

Convert any OpenAPI/Swagger spec into per-endpoint LLM tool definitions (function calling schemas) plus clean Markdown docs. Generates JSON-schema tools ready for OpenAI, Claude/Anthropic, and any agent framework. Paste a spec URL or inline JSON; deterministic, content-hashed output per endpoint.
