How this service works
Global market, government and reference data for AI agents. Pay-per-call over x402 (USDC on Base mainnet).
Output
Returns structured metadata about the requested NPM package, including its name, latest version, description, license, author/maintainers, dependencies, repository URL, and potentially download statistics.
Example use cases
Checking package version before install
“What is the latest published version of the 'axios' npm package and who maintains it?”
License compliance audit
“I need to check the license type for the npm package 'moment' — can you pull that info for me?”
Dependency research for a new project
“Look up the npm package 'express' and give me its description, current version, and a list of its dependencies.”

Endpoint
POSThttps://worlddata402.worlddata402.workers.dev/v1/packages/npm/%7Bname%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need quick, pay-per-call lookups of npm package metadata without setting up a dedicated npm registry API key. It is especially suited for AI agents operating autonomously with on-chain micropayment capability via x402 on Base mainnet, avoiding subscription overhead for infrequent lookups.
Side effects
- Package name not found — returns 404 or empty result
- Invalid or malformed package name — may return error
- Payment failure over x402 — call not executed
- Rate limiting or quota exceeded — call rejected
- Package exists but has no published versions — incomplete metadata returned
