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 original query, the ecosystem searched, a result count, and an array of matching packages each with name, version, description, and links (npm/cargo page, bugs tracker, homepage, repository).
Example use cases
Discover MCP server packages on npm
“Search npm for packages matching 'mcp server' and return the top 10 results with their names, versions, and links.”
Find Rust crates for cryptography
“Search the cargo registry for crates related to 'cryptography' and give me up to 8 results with descriptions and repository links.”
Audit available authentication libraries
“Can you search npm for packages matching 'oauth authentication' and return the top 5 so I can evaluate which one to use in my project?”
Technical details
Endpoint
POSThttps://x402.datakoot.com/api/package_search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to search npm or cargo package registries by keyword or description to discover libraries, evaluate options, or find specific packages. It is especially useful for AI agents doing dependency research, auditing available tooling, or recommending libraries to developers. Prefer this over scraping npm.js or crates.io directly since it returns structured JSON with links and version data in a single call.
Side effects
- Invalid ecosystem value (not npm or cargo) returns a validation error
- Empty or overly broad query returns too many low-relevance results
- Package registry unavailable causes a service error
- Limit value out of expected range may be rejected or clamped
- Payment failure via x402 means the call is not charged and the response is not returned
