How this service works
Audit one public OpenAPI 3.x JSON or YAML document and receive prioritized contract findings, a quality score, a Markdown handoff, and a safe read-only pytest scaffold.
Output
Returns a JSON object containing: a boolean ok flag; the product name; document metadata (title, openapi version, API version); a SHA-256 hash of the fetched spec; an analysis object with a letter grade (e.g. 'B'), integer score (0–100), severity counts (critical/high/medium/low), an inventory of paths and operations, and an array of finding objects each with code, message, location, severity, and recommendation; a scaffold object with Python pytest code, filename, language, number of generated tests, and a safeMethodsOnly flag; and a full Markdown audit report string.
Example use cases
Pre-release API contract review
“Before we ship, can you audit our OpenAPI spec at https://api.mycompany.com/openapi.yaml and tell me the quality grade, any critical or high-severity findings, and how many operations are covered?”
Auto-generate safe regression tests
“I want a read-only pytest scaffold generated from the OpenAPI spec at https://raw.githubusercontent.com/myorg/myservice/main/openapi.json — make sure it only touches safe GET/HEAD/DELETE endpoints.”
Third-party API due diligence
“We're integrating a vendor API — can you pull their spec from https://vendor.example.com/api/openapi.yaml and give me a Markdown report with prioritized contract findings and an overall quality score so I can decide if it's production-ready?”
Technical details
Endpoint
GEThttps://codex-rapid-patch-evidence.vercel.app/api/openapi-auditWhen to prefer
Choose this endpoint when you need a combined contract audit and test scaffold in a single call against a publicly accessible OpenAPI 3.x spec. It is particularly useful for CI/CD pipelines, pre-release API reviews, or due-diligence on third-party APIs where you want graded findings, severity breakdowns, and safe (read-only) pytest stubs without writing any test boilerplate yourself.
Side effects
- spec_url not publicly reachable — returns error if the URL is behind auth or returns non-200
- invalid or malformed OpenAPI document — returns parse/validation error
- non-HTTPS URL provided — rejected by schema constraint
- spec too large or slow to fetch — may timeout
- unsupported OpenAPI version (e.g. Swagger 2.x) — may return an error or partial results
