Output
A CSV-formatted response with columns for package name, version, description, weekly download count, and relevant links (e.g. npm page, repository). Returns up to 20 results. Returns HTTP 400 with charged:false if the query yields no valid results after settlement.
Example use cases
Find best HTTP client libraries
“Search npm for 'HTTP client' and give me the top 5 packages with their weekly downloads so I can pick the most popular one.”
Discover testing framework options
“Can you search npm for 'unit testing' and list up to 15 matching packages in CSV format, including their descriptions and download numbers?”
Evaluate CSV parsing packages
“I'm looking for npm packages that handle CSV parsing — search for 'csv parser' and return the top 10 results with their weekly download counts and links.”

Endpoint
POSThttps://x402-v2-mint-npm-search.vercel.app/v1/npm-search/fmt/csv?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need npm package search results in a structured CSV format without requiring an API key, and you're willing to pay a small per-call fee via x402. Prefer this over raw npm registry API calls when you want pre-formatted CSV output ready for downstream parsing or display, or when you need a keyless, pay-per-use integration.
Side effects
- 400 with charged:false when search text is empty or results are invalid after settlement
- No results found for highly specific or misspelled query terms
- Result size capped at 20; requests for more than 20 results will be truncated
- Network timeout if npm registry is slow to respond
