Example prompt: Can you look up the module and type entrypoints for the fastify npm package at version 4.28.0, so I can see how to correctly import it in an ESM project?

## When to prefer this

Use this endpoint when you need structured, registry-level metadata about fastify's module and type entrypoints specifically — for instance when planning ESM/CJS compatibility, auditing TypeScript type paths, or evaluating breaking changes between versions. Prefer this over raw npm registry calls when you want a pre-parsed, agent-ready summary scoped to entrypoints.

## Known failure modes

- Unknown or misspelled package name returns no results or an error
- Requested version does not exist in the npm registry
- Registry metadata unavailable or rate-limited upstream
- Response may be incomplete if the package has an unusual or missing exports field
