Output
Returns a list of up to 20 npm packages in a custom concierge format, each entry including the package name, version, description, weekly download count, and relevant links (e.g. npm page, repository). Returns a 400 with charged:false if the query yields no valid results or is invalid.
Example use cases
Find a CSV parsing library
“Search npm for CSV parsing packages and show me the top 3 results — I want to know the name, version, weekly downloads, and a short description of each.”
Discover React UI component libraries
“Can you search npm for 'React UI component library' and give me up to 10 results? I need the package names, their descriptions, and how many weekly downloads they get.”
Evaluate HTTP client options for Node
“Search npm for HTTP client packages for Node.js — give me the top 8 results with name, version, description, and weekly downloads so I can pick the best one.”
Technical details
Endpoint
POSThttps://x402-v2-mint-npm-search.vercel.app/v1/npm-search/fmt/custom?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to search the npm registry without API keys, want structured package metadata (name, version, description, downloads, links) returned in a clean custom format, and are operating in an x402 micropayment context at $0.005 USDC per query. Prefer this over scraping npm.io directly or using the raw npm registry search API when keyless access and concierge-formatted output are priorities.
Side effects
- Empty or meaningless search text returns 400 with charged:false
- Requesting more than 20 results may be capped or rejected
- Network or npm registry outage causes upstream failure
- Malformed POST body (missing 'text' field) returns 400
