Example use cases
Check latest Rust crate version
“What's the latest version of the 'tokio' crate and what does it do? Just give me the name, version, and a short description.”
Audit package license before use
“I need to check the license for the 'reqwest' crate before we use it in our project — can you look it up and return the license and maintainer info?”
Verify a crate exists before referencing it
“Does a crate called 'hyper' exist on crates.io? If so, return its description and download count.”

Endpoint
GEThttps://workspace-x402-paywall.onrender.com/dev/crates?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need quick, pay-per-call package metadata lookups for Rust crates or Python packages without setting up a full API key or subscription. Ideal for agents that infrequently query package registries and want to pay micro-amounts per lookup via USDC on Base or Solana.
Side effects
- Crate name not found — returns empty or error object
- Invalid or misspelled crate name — no results
- Payment rejected — x402 USDC payment on Base or Solana mainnet fails
- Rate limiting or server downtime on render.com free tier
- Fields parameter ignored or partially supported
