## Endpoints and jobs

| Endpoint | Job | Price | Runs (30 days) | Benchmark |
|---|---|---|---|---|
| [Manifest of a package version (latest by default)](/public-catalog/npm-registry-package) | `developer.package.manifest` | free | 55% of 20 runs without an error, median 270 ms | no benchmark yet |
| [Daily download counts of a package](/public-catalog/npm-registry-downloads-daily) | `developer.package.downloads.daily` | free | 100% of 14 runs without an error, median 432 ms | no benchmark yet |
| [Search npm packages](/public-catalog/npm-registry-search) | `developer.package.search` | free | 100% of 11 runs without an error, median 320 ms | no benchmark yet |
| [Total downloads of a package over a period](/public-catalog/npm-registry-downloads) | `developer.package.downloads` | free | 90% of 10 runs without an error, median 442 ms | no benchmark yet |

## How the numbers are measured

Run numbers are looot's own runs of each endpoint over the last 30 days: the share that completed without an error, and the median time to answer. An endpoint with fewer than 10 runs in that window shows "not enough runs to rank" and is never ranked. Prices are what looot charges per call or per result, fee included, read from the live catalog; you prepay credit and each call is charged when it runs.
