## 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 ddg-agent-tool-schema-repair-a7772067 -d '<json body>'
```

Example prompt: I have a broken agent tool schema — the input is a POST with a JSON body and the output should return {ok: true} — can you repair and normalize it so it's valid and usable?

## When to prefer this

Use this endpoint when an AI agent's tool schema (input/output definition for an HTTP tool) is malformed, invalid, or failing validation and needs programmatic repair. Prefer this over manual schema editing when operating in automated pipelines or agent orchestration systems where schema correctness must be verified at low cost ($0.02 USDC per call) via x402 payment rails.

## Known failure modes

- Missing required 'input' or 'output' fields returns a validation error
- Unsupported HTTP method (not POST, PUT, or PATCH) is rejected
- Invalid bodyType value outside allowed enum causes rejection
- Malformed or unparseable body object may cause repair failure
- Payment not completed (x402) results in 402 response before processing
