Does it enforce a specific style?

No, it detects the convention most used in your spec and flags the outliers.

Which conventions are checked?

Path casing, resource pluralisation, parameter naming, error response shape and pagination parameters.

Is anything uploaded?

No — the audit runs fully client side.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.

Do I need an account or an API key?

No. Every tool on Coders Hub is free to use with no sign-up, no API key and no usage limits.

No inconsistencies detected — naming looks uniform.

About the API Consistency Auditor

Check that your endpoints follow one convention: path casing, resource pluralisation, parameter naming style, consistent error responses and uniform pagination. The auditor infers the dominant convention in your spec and reports every operation that deviates from it.
