API Testing
Validate API contracts, behaviors, and edge cases continuously.
API validation ensures your services communicate correctly-contract compliance, error handling, rate limiting, authentication flows, and data transformation. In microservices architectures, API reliability is system reliability.
What this validation covers
Structured capability coverage for teams that need repeatable signal instead of brittle scripts and one-off audits.
Why teams need it
API contract tests validate schema, but production breaks from behavior. Rate limiting works in tests but fails under load. Authentication flows pass individually but break in sequences. Traditional API testing is structural, not behavioral.
How Zof approaches it
The API Agent maps your API dependency graph through the System Graph, understanding how services communicate in real flows. It validates behavior under realistic conditions-authentication sequences, rate limiting under load, error propagation across services.
Failure modes it catches
Contract-compliant responses with incorrect behavior
Authentication state not properly propagated
Rate limiting failures under realistic load patterns
Error responses that break downstream consumers
Data transformation edge cases in nested objects
Timeout cascades across service dependencies
Business impact
Prevent service-to-service communication failures
Catch breaking changes before deployment
Ensure consistent error handling
Reduce integration debugging time by 80%
Flexible pricing by maturity
Start with a focused validation program and expand to full enterprise orchestration as your reliability program grows.
