How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object containing the crate name, latest published version string, total and recent download counts, GitHub repository URL, human-readable description, and source metadata including when the data was fetched and when it expires.
Example use cases
Dependency version check for Rust project
“What's the latest version of the 'serde' crate and how many total downloads does it have?”
Evaluating crate popularity before adoption
“I'm considering using 'axum' in my project — can you pull its crates.io metadata so I can see how active and popular it is?”
Automated dependency audit in CI pipeline
“For my Rust dependency audit, can you fetch the current crates.io info for 'reqwest' including version, downloads, and the source repository?”
Technical details
Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/dev/crate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, up-to-date metadata for a specific Rust crate from crates.io, especially latest version, download statistics, and repository URL. Prefer this over scraping crates.io directly or using general web search when you need machine-readable, reliably structured output with a known freshness window.
Side effects
- Package name not found on crates.io — returns an error or empty result
- Package name too long (over 200 characters) or empty — rejected by schema validation
- crates.io API unavailable or rate-limited — may return stale or failed response
- Misspelled crate name — returns not-found rather than fuzzy match
