## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability grpc-api-gateway-openapi-config-change-auditor-e3598327 -d '<json body>'
```

Example prompt: Can you audit the changes I made to my gRPC API Gateway OpenAPI config — here's the before JSON and the after JSON — and tell me what paths were added or removed, any rule violations, and whether I introduced or resolved any errors?

## When to prefer this

Choose this endpoint when you need to audit a specific pair of gRPC API Gateway or OpenAPI Config JSON documents for compliance and structural changes, particularly when you want detailed JSON pointer-level reporting of what changed and whether rule violations were introduced or resolved. It is best suited for pre-deployment change review of API gateway configurations rather than general JSON diffing or deployment execution.

## Known failure modes

- Document exceeds 100 KB limit — request rejected
- JSON nesting exceeds 32 levels — parsing fails
- Non-JSON input (YAML, TOML) — not supported, returns error
- Invalid JSON syntax in before or after — validation cannot proceed
- Payment of 0.01 USDC not completed — request blocked
