# CI Log Fast Diagnosis

> CI Log Fast Diagnosis is a paid API for AI agents from codex-rapid-patch-evidence.vercel.app, paid per call via x402, $1/call, status unknown (last checked 2026-09-14).

Analyzes raw CI log text to identify failing steps, primary errors, and root causes, returning structured findings, a Markdown report, and safe rerun recommendations without executing any commands.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 ci-log-fast-diagnosis-2a8a181f -d '<json body>'
```

Example prompt: Here's the raw log output from my failing GitHub Actions workflow — can you diagnose what's going wrong and tell me which step is failing, what the primary error is, and what I should fix first? Context: TypeScript monorepo on Node 20.

## When to prefer this

Choose this endpoint when you need a fast, safe, read-only diagnosis of a CI log without any risk of command execution or side effects. It is ideal for quick triage of failing builds where you want structured findings and a Markdown handoff report rather than a full reproduction workflow. Prefer the more expensive /api/ci-log-triage endpoint when you need a full reproduction handoff; use this endpoint for initial fast diagnosis at $1 per call.

## Known failure modes

- Log text exceeds 120,000 character limit — request rejected
- Malformed or empty log input returns no findings
- Ambiguous log format may result in incorrect tool detection
- Non-CI log content (e.g. application logs) may yield low-confidence or empty findings
- Network timeout if log is very large near the limit

## How this service works

Audit one public OpenAPI 3.x JSON or YAML document and receive prioritized contract findings, a quality score, a Markdown handoff, and a safe read-only pytest scaffold.

## Output

Returns a structured JSON object with: identified primary failure (error code, message, severity), failing step name, counts of errors and warnings, list of detected tools (e.g. npm, typescript), an array of findings, actionable recommendations, a Markdown diagnosis report, a SHA256 of the log, a safe rerun command list with executeAutomatically=false, and safety metadata confirming no commands were executed during analysis.
