OpenAPI explainer
AIPaste YAML or JSON from an OpenAPI 2.x / 3.x document—often a single path, operation, or schema. You'll get a concise summary of methods, parameters, and responses. No HTTP traffic is sent from this page.

Common use cases
- Skim a single path or operation from a large spec during code review.
- Compare generated OpenAPI from JSON samples with the JSON → OpenAPI draft tool.
- Pair with the curl & HTTP explainer when debugging requests.
Common mistakes to avoid
Pasting production API keys into the spec
Redact tokens and example credentials. Treat pasted text as potentially processed server-side.
Assuming runtime matches the document
Specs can drift from deployment. Verify behavior against your environment.
FAQ
Are requests sent to my API?
No. This tool only explains the text you paste.
Does it resolve every $ref?
It summarizes what is visible. Large or external refs may need your local bundler.
