npm Registry API
Package metadata and download counts from the npm registry.
Authentication
No API key is needed for basic use, which makes it ideal for prototypes, but respect the provider's fair-use policy and cache results where allowed.
Pricing model
The provider offers this API free of charge. Check the terms for rate limits and any attribution rules. Prices change often, so check the provider's pricing page before you commit, and model your bill at 10× today's volume.
Before you integrate
- Read the terms on caching, storing and displaying data.
- Note the rate limits and the error format so you can retry with backoff.
- Wrap calls behind your own interface so you can switch providers later.
- Pin an API version if the provider offers versioning, and watch its changelog.
