## 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-alexweb-space-root-cause-analysis-f23388cf -d '<json body>'
```

Example prompt: I'm getting a NullPointerException in production — here's the issue description: 'service crashes on user login', the stack trace from our logs, and the relevant authentication code. Can you do an evidence-ranked root-cause analysis and tell me exactly what's causing it?

## When to prefer this

Choose this endpoint when you need structured, evidence-backed root-cause analysis that synthesizes multiple signals — issue text, logs, and code — rather than simple keyword search or a single-source log scan. Particularly valuable for complex production incidents where the cause isn't obvious from any single artifact.

## Known failure modes

- Missing or empty issue field may produce vague or low-confidence results
- Truncated or malformed logs may cause incomplete analysis
- Very large code context may exceed input limits
- Ambiguous issue descriptions without logs or code context may yield generic results
- Payment failure (402) if USDC balance is insufficient

## How this service works

Evidence-ranked root-cause analysis from issue text, logs and supplied code context.

## Output

An evidence-ranked list of root causes for the described issue, with supporting evidence drawn from the provided logs, stack traces, and code context — prioritizing the most likely causes based on correlation across all supplied inputs.
