Test AI APIs before launch

Test injection, unstable outputs, and boundary breaks on completion endpoints.

Your API is an attack surface even without a chat UI.

What can go wrong

• Hostile payloads in API inputs change behavior.
• Responses leak training-adjacent or internal context.
• Outputs vary wildly under edge inputs.

Why happy-path testing misses this

• Contract tests rarely include adversarial payloads.

What Agnostics tests

• Prompt injection
• Hallucination pressure
• Boundary bypass
• Permission abuse

Useful finding example

Injection finding via nested JSON field in API request body.

Release Gate

Fix when API exposes sensitive patterns to unauthenticated callers.
