Notes

No account is needed for these reads. crates.io asks for at most one request per second: space calls out.

  • Search defaults to relevance and page 1, with up to 10 results per page. The optional sort is relevance, downloads (all time), recent-downloads, recent-updates, new, or alpha. page is a positive whole number. Versions are sorted by publication date, first page only, up to 100. Reverse dependencies return the first page, up to 10.
  • The category index returns up to 100 categories. Keyword listings return the first 10 crates, sorted by recent downloads.
  • defaultVersion is the version selected by crates.io for the crate page, not necessarily the highest version. The detail license belongs to that version. Links and license can be null.
  • Pass an exact published version to getDependencies. Its req is a Cargo version requirement; kind distinguishes normal, build and development dependencies.
  • Reverse dependency versions are versions of the dependent crates, not requirements on the queried crate. Owners can be users or teams; their names can be null.
  • A nonexistent crate returns an input error. Publishing, yanking and owner changes are not covered.

About these operations

Each operation is a request learned from crates.io's own web pages: API Anything replays it over plain HTTP and falls back to a browser when it must. Read them as JSON.
