How this service works
npm latest version - Fetch the latest version of any npm package by querying the npm registry's /latest endpoint and returning the package version.. Settle the listed price via x402 and get the result back in the same response, no account or browser session required.

Returns the latest version string (e.g. '18.2.0') of the specified npm package as published to the npm registry's /latest dist-tag, delivered as a text response from the agent.
Example use cases
Dependency version check for project setup
“What's the latest version of 'typescript' on npm? I want to make sure I'm installing the most up-to-date release.”
Automated changelog or release monitoring
“Can you check what the current latest version of 'next' is on npm — I want to know if there's been a new release since 14.2.”
Package research before adding a dependency
“Before I add 'zod' to my project, can you look up the latest version available on npm so I know what to pin in my package.json?”
Technical details
Endpoint
POSThttps://www.amnt.io/api/agent/sunny_tundra/npm-latest-versionWhen to prefer
Use this endpoint when you need a quick, pay-per-call lookup of an npm package's latest version without setting up npm CLI access, registry credentials, or a browser session. Ideal for AI agents automating dependency checks, release monitoring, or documentation generation tasks where a lightweight, stateless HTTP call is preferred over running npm commands directly.
Side effects
- Package name does not exist on npm — registry returns 404, agent returns an error or empty result
- Misspelled or ambiguous package name yields incorrect or no result
- npm registry temporarily unavailable — request times out or returns a 5xx error
- Private or scoped packages may not be accessible without auth credentials
- Payment settlement failure via x402 protocol prevents the call from completing
