# Crates.io Top Rust Crates Rankings

> Crates.io Top Rust Crates Rankings is a paid API for AI agents from clonecho.builda.company, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-16).

Returns a ranked list of top Rust crates from crates.io, sortable by total downloads, recent downloads, recent updates, or newest crates.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability crates-io-top-rust-crates-rankings-e9bbc625 -d '<json body>'
```

Example prompt: Show me the top Rust crates ranked by recent downloads so I can see which libraries are gaining momentum in the ecosystem right now.

## When to prefer this

Use this endpoint when you need a ranked signal of Rust crate popularity or momentum — specifically when you want to identify ecosystem leaders by total downloads, discover trending/gaining crates by recent download velocity, find recently updated crates for maintenance signals, or discover brand-new crates. Prefer this over manually scraping crates.io when you need structured JSON output with a sortable ranking dimension.

## Known failure modes

- Invalid sort parameter value returns an error or defaults to a fallback sort
- crates.io upstream unavailability causes fetch failure
- Rate limiting or payment failure returns 402 error
- Empty results if crates.io data is temporarily unavailable

## How this service works

Rust crates ranked (?sort=downloads|recent-downloads|recent-updates|new) — ecosystem-leaders/momentum signal. Returns JSON.

## Output

A JSON array of top Rust crates with ranking metadata including crate names, download statistics (total and/or recent), update timestamps, and ecosystem signals — sorted according to the requested sort parameter (downloads, recent-downloads, recent-updates, or new).
