What is API Contract?

An API Contract is a formal, binding specification defining the endpoints, inputs, outputs, error conditions, and SLA guarantees agreed upon between API providers and consumers.

Detailed Explanation

API contracts prevent breaking changes by guaranteeing payload shapes, status codes, and security requirements. OpenAPI specifications serve as formal executable API contracts.

Common Mistakes to Avoid

Introducing breaking changes without bumping major API version
Making schema fields non-optional without notice

Audit API Contract Quality

Paste any OpenAPI specification URL or YAML file into APIForge for instant 0-100 quality scoring, schema linting, and zero-CORS proxy testing.
