How this service works
DeAI artifact gateway: reuse (package_check). Deterministic JSON with byte-exact quotes for $0.0100; no crawl, no bot walls.
Output
A deterministic, byte-exact JSON object containing npm registry metadata for the 'left-pad' package, including version history, description, author, license, and distribution details — served without crawling or bot-wall interference.
Example use cases
Dependency audit for JS project
“I need to verify that the left-pad npm package is still published and get its latest version number — can you pull the registry metadata for it?”
Package existence check before install
“Before I add left-pad as a dependency, can you confirm it exists on npm and grab its full package info?”
Retrieve deterministic npm artifact for caching
“Fetch the byte-exact JSON artifact for the left-pad npm package so I can store it for deterministic dependency resolution.”
Technical details
Endpoint
GEThttps://research.zaiba.cloud/api/v1/package/npm/left-pad?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need a deterministic, byte-exact npm registry JSON for the left-pad package without hitting npm's public API directly (which may have bot walls or rate limits). Ideal for dependency auditing, reproducible builds, or caching pipelines where exact artifact fidelity matters and a $0.01 per-call cost is acceptable.
Side effects
- Package not found (404) if the package name is incorrect or unpublished
- Payment failure if the $0.01 USDC x402 payment is not properly attached
- Rate limiting or authentication errors if the gateway rejects the request
- Stale or cached data if the registry artifact has not been refreshed recently
