API Contracts

Check responses against the contracts that describe them. All analysis uses the content you paste and runs locally.

Tools

API Response Validator

Match captured status and Content-Type against pasted OpenAPI 3.1 or 3.2, then validate the response body using the selected contract.

OpenAPI Response Validator

Select an operation, documented response and media type from pasted OpenAPI 3.1 or 3.2, then validate a complete JSON or text example.

API Contract Drift Checker

Compare JSON Schema API contracts from request and response perspectives. Review directional breaking changes without a guessed SemVer verdict.

Documented example or captured response?

OpenAPI Response Validator starts from a response contract you select. API Response Validator starts from a captured status and Content-Type, then finds the documented match. Both accept a pasted single OpenAPI 3.1/3.2 document and complete JSON or ordinary text bodies. Contract Drift Checker instead compares two extracted JSON Schemas from request and response perspectives.

Use the Workbench when the contract format is unclear.
