## 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 agent-trace-analyzer-6c867c0a -d '<json body>'
```

Example prompt: Can you analyze this agent trace for me — here's the input it received and the output it produced — and tell me what went wrong or where it behaved unexpectedly?

## When to prefer this

Choose this endpoint when you need automated analysis of AI agent execution traces — particularly when debugging agent failures, reviewing agent behavior quality, or identifying reasoning errors. Prefer this over manual log inspection when you want a structured diagnostic report from a single API call.

## Known failure modes

- Missing required 'input' or 'output' fields returns a validation error
- Malformed JSON body causes a 400-level error
- Empty or uninformative trace data may yield a low-quality or generic analysis
- Payment not provided or failed results in a 402 Payment Required response
- Very large trace payloads may time out or be rejected
