## How to call it through Zero

```sh
zero fetch --capability agent-trace-brief-2e5c3097
```

Example prompt: Can you scan this agent run trace JSON for failures, timeouts, and auth or payment errors and give me a compact risk report? Here's the trace: {"steps":[{"tool":"web_search","status":"timeout","duration_ms":30000},{"tool":"payment","status":"auth_error"}]}

## When to prefer this

Use this endpoint when you need a fast, structured risk summary of an AI agent's execution trace, particularly to surface failures, timeouts, and auth/payment errors without manually parsing verbose log output. Ideal for agent observability pipelines, post-run diagnostics, and pre-deployment health checks on agent runs.

## Known failure modes

- trace_json parameter missing or empty — returns validation error
- Trace JSON exceeds 64,000 character limit — rejected with size error
- Malformed or unparseable JSON in trace — may return partial results or parse error
- No failures detected — returns empty or clean risk report
- Payment not completed via x402 — returns 402 Payment Required

## How this service works
