How this service works
npm package profile: latest version, description, license, repository, dependencies, unpacked size, weekly and monthly downloads, maintainers and deprecation flag. For dependency choice and audits.
Output
A JSON object containing the package name, latest version, description, license, repository URL, homepage URL, number of versions, last modified date, number of dependencies with their names listed, number of maintainers, weekly and monthly download counts, unpacked size in KB, required Node.js version, deprecation status, and data source label.
Example use cases
Vetting a new dependency before adoption
“Before I add 'axios' to my project, can you check its npm profile — specifically the latest version, license, how many dependencies it has, weekly download count, and whether it's been deprecated?”
Auditing an existing package for security review
“I'm doing a dependency audit — can you look up the npm package 'moment' and tell me if it's deprecated, who maintains it, what the latest version is, and how many dependencies it pulls in?”
Comparing package health for a tech decision
“We're deciding between 'dayjs' and another date library — can you fetch the npm profile for 'dayjs' including monthly downloads, maintainer count, unpacked size, and the current version so we can compare?”
Technical details
Endpoint
POSThttps://api.vextorium.com/npm-paquete-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single, comprehensive npm package profile in one call — covering stats, metadata, dependencies, and health signals — rather than making multiple raw npm registry API calls. Ideal for dependency audits, automated tech-stack analysis, or agent workflows that need to evaluate or compare packages programmatically.
Side effects
- Package name not found on npm registry — returns null fields or empty response
- Typo in package name yields no match
- Private or scoped packages may not be accessible
- Deprecated packages return a non-null 'obsoleto' field which agents should check
- Rate limiting or network issues may cause timeouts
- Missing 'nombre' field in request body causes validation error
