How this service works
Pay-per-call tools for AI agents: web page text extraction and summaries, screenshots, image generation, speech-to-text, image description, domain and email-auth intelligence, and live Base token and wallet lookups. No account or API key; pay per request in USDC on Base via x402.
Output
Returns a JSON object with the package name, ecosystem, existence flag, age in days, a safety verdict string (e.g. 'ok'), list of licenses, list of security advisories, deprecation status, repository URL, total version count, latest version string, weekly download count, and count of known vulnerabilities.
Example use cases
Pre-install dependency security check
“Before I add 'requests' from PyPI to my project, can you check if it has any known vulnerabilities or security advisories?”
License compliance audit
“What license does the npm package 'moment' use, and is it still actively maintained or deprecated?”
Supply chain vetting for new package
“I've never used the Cargo crate 'serde' before — can you tell me how old it is, how many versions it has, and whether there are any known security issues?”
Technical details
Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/package?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to programmatically vet an open-source package before recommending or installing it — especially for security verdicts, license checks, or deprecation status — without requiring an account or API key. Ideal for autonomous coding agents that want a pay-per-call, no-setup solution covering npm, PyPI, Cargo, Go, Maven, and NuGet in a single API.
Side effects
- Package not found in the specified ecosystem — exists:false returned
- Invalid ecosystem name causes validation error
- Typo in package name returns no results
- Scoped npm packages (e.g. @scope/name) must be URL-encoded correctly
- Rate or quota issues may return HTTP 402 if payment fails
