How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

Output

Returns a JSON object with package metadata from the npm registry, including fields such as name, version, description, author, license, dependencies, and publication timestamps. The response includes an 'ok' and 'paid' status field confirming the microtransaction was processed.

Example use cases

Check latest npm package version

“What's the latest published version of the 'express' npm package and when was it released?”

Audit unfamiliar dependency

“I found 'left-pad' listed as a dependency in a project — can you pull up the npm package info so I can see what it does and who maintains it?”

Verify package existence before install

“Before I add 'axios' to my project, can you check the npm registry and confirm it exists and grab its description and homepage?”

Endpoint

GEThttps://x402-toolbox.shablony-pro.workers.dev/dev/npm-package-info?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need quick, pay-per-use npm package metadata lookups without managing API keys or OAuth. It is ideal for AI agents operating autonomously in environments where per-call micropayments via USDC on Base are preferable to subscription-based npm registry APIs. Best suited for occasional or on-demand lookups rather than bulk registry crawling.

Side effects

Package not found in npm registry — returns error or empty result
Invalid or malformed package name input — may return validation error
Network or upstream npm registry timeout — transient failure
x402 payment failure — if USDC balance is insufficient the call is rejected before execution
