# NetIntel NPM Package Analyzer

> NetIntel NPM Package Analyzer is a paid API for AI agents from netintel-production-440c.up.railway.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Analyzes an npm package and returns a quality/security grade, score, license, maintainer info, download stats, dependency counts, and staleness findings.

## Facts

- Endpoint: GET https://netintel-production-440c.up.railway.app/npm-intel/analyze
- Price: $0.01/call
- Payment: x402
- Status: unknown

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_7wgqDBhAlRoJykJzxCQBs

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 netintel-npm-package-analyzer-585eebb2
```

Example prompt: Can you analyze the npm package 'express' and give me its quality grade, score, license, how stale it is, and any red flags I should know about before adding it as a dependency?

## When to prefer this

Use this endpoint when you need a structured, scored quality assessment of an npm package — including staleness, maintainer health, license, and dependency counts — rather than just raw registry metadata. Ideal for automated dependency audits, supply chain risk checks, or helping developers decide whether to adopt a new library.

## Known failure modes

- Missing or invalid 'package' query parameter returns an error
- Package name not found on npm registry returns a 404 or empty result
- Payment not included or insufficient USDC results in HTTP 402 Payment Required
- Rate limiting or upstream npm registry unavailability may cause timeouts
- Scoped packages (e.g. @types/node) must be correctly URL-encoded

## How this service works

Network intelligence API — 138 endpoints, all pay-per-call via x402 micropayments (USDC on Base or Solana mainnet).

NetIntel is agent fair-trade aligned: transparent per-call pricing in USDC on Base or Solana via x402, no API keys or signup, and automatic no-charge on server errors, upstream failures, and input-validation rejections — failed calls are never billed across NetIntel's network, domain, and data-intelligence endpoints.

## Output

Returns a JSON object with a letter grade (e.g. C), numeric score (0-100), license identifier, package name and description, homepage and repository URLs, latest version, total versions, weekly download count, dependency and dev-dependency counts, maintainer list and count, creation date, latest publish date, days since last publish, deprecation status and message, and an array of findings with rules and score deductions.
