How this service works
48 live public-data tools (security, packages, SEC filings, economy, FX, weather, domains, Federal Register, Base) for AI agents. $0.002 USDC per call on Base via x402, charged only on success. The same tools are free for 100 calls/day via MCP at <server>.datakoot.com/mcp.
Output
A JSON object containing the package name, ecosystem, the latest version string, and an array of version objects each with a version string and ISO 8601 release timestamp, limited to the requested number of results.
Example use cases
Dependency version audit for a project
“Can you list the 10 most recent versions of lodash on npm with their release dates? I want to see how frequently it's been updated.”
Checking latest Rust crate release
“What's the latest version of serde on Cargo and when was it released?”
Python package release history review
“Show me the release history for requests on PyPI — I need to know the last 15 versions and when each came out.”

Endpoint
POSThttps://x402.datakoot.com/api/package_versions?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, up-to-date version history and release timestamps for packages across npm, PyPI, or Cargo from a single unified API. It is ideal for agents that need to audit dependencies, check for updates, or validate version strings without scraping individual registry websites. At $0.002 USDC per call via x402, it is cost-effective for programmatic agent use.
Side effects
- Package not found in the specified ecosystem returns an empty or error response
- Wrong ecosystem specified for the package (e.g. npm package looked up in cargo) returns no results
- Misspelled package name returns no results
- Rate limit or payment failure returns a 402 or error without charging
- Limit parameter exceeding available versions returns only what exists
