# Agent Dev Preflight API – Package Risk Check

> Agent Dev Preflight API – Package Risk Check is a paid API for AI agents from agent-dev-preflight-api.bonkoturyu.workers.dev, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).

Returns a deterministic risk assessment for an npm or PyPI package version using OSV vulnerability data and registry metadata.

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 agent-dev-preflight-api-package-risk-check-b88ae562 -d '<json body>'
```

Example prompt: Before I install it, can you run a risk preflight on lodash version 4.17.20 from npm and tell me if it has any known vulnerabilities or registry red flags?

## When to prefer this

Choose this endpoint when you need a fast, deterministic, per-version security check on a specific npm or PyPI package — especially in automated pipelines, CI gates, or agentic workflows where you want OSV vulnerability data plus registry metadata signals without spinning up a full SCA tool. Prefer it over general-purpose vulnerability scanners when you have an exact pinned version and need a lightweight, pay-per-call preflight with no setup.

## Known failure modes

- Version range submitted instead of exact version — rejected with validation error
- Package name or ecosystem not found in registry — returns not-found or error response
- OSV data temporarily unavailable — upstream lookup failure
- Invalid ecosystem value (only 'npm' and 'PyPI' are accepted) — schema validation error
- Package name exceeds 214 character limit — rejected by input validation
- Payment not provided or insufficient — 402 payment required response

## How this service works

Deterministic package risk preflight using OSV and registry metadata.

## Output

A deterministic risk report for the specified package version, including OSV vulnerability matches, registry metadata signals (e.g. maintainer activity, publish anomalies), and an overall risk indicator — all scoped to the exact installed version provided.
