How this service works

Pay-per-call tools for AI agents: x402 pre-flight checks (is this endpoint safe to pay?), web pages as clean markdown (with optional JavaScript rendering), Latin American tax-ID validation, npm/PyPI/GitHub lookups, and URL health checks. No API keys, no accounts — pay per request in USDC.

Output

Returns a JSON object with the package name, latest version string, SPDX license identifier, GitHub (or other) repository URL, total number of dependencies, last publish timestamp, and weekly download count.

Example use cases

Check package version before upgrading

“What's the latest version of lodash on npm, and when was it last published? I want to know if it's been recently maintained before I upgrade.”

Verify open-source license compatibility

“I need to check what license the 'axios' npm package uses before I include it in my commercial project — can you look that up?”

Assess package popularity for dependency decision

“How many weekly downloads does 'moment' get on npm, and how many dependencies does it pull in? I'm trying to decide if it's worth adding to my project.”

Technical details

Endpoint

POSThttps://agents.supremeai.ca/v1/npm/package?utm_source=zero.xyz

When to prefer

Use this endpoint when you need quick, structured npm package metadata without setting up an API key or account — ideal for AI agents that need to verify package details, check licenses, or assess popularity on the fly. Prefer over scraping npm's website or using the full npm registry API when you only need summary stats and want a simple pay-per-call model.

Side effects

Package not found — returns an error if the package name does not exist on npm
Scoped package name malformed — incorrect use of '@scope/pkg' format may return an error
Network/upstream timeout — npm registry may be temporarily slow or unavailable
Payment failure — USDC payment not confirmed, request not processed
