## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sitecheck-web-intel-npm-registry-search-for-markdown-to-pdf-mcp-6e517dff
```

Example prompt: Search the npm registry for MCP server packages that convert Markdown to PDF and show me the top 5 results with their descriptions, publishers, and monthly download counts.

## When to prefer this

Use this endpoint when you need to programmatically discover npm packages specifically in the markdown-to-pdf MCP category without requiring an API key. It is ideal for agent workflows that need to survey available tooling, compare publisher metadata, or track download popularity. Prefer it over a generic npm search UI when you need structured data suitable for downstream comparison or selection logic.

## Known failure modes

- npm registry search API unavailable — may return 5xx or timeout
- Query too long (over 100 characters) — rejected by input validation
- Limit out of range (not 1–20) — rejected by input validation
- No matching packages found — returns empty list
- npm API rate limiting — may produce transient errors

## How this service works

npm registry search for MCP servers that convert Markdown to PDF (public npm search API, no key): package name, version, description, publisher, last publish date, monthly and weekly downloads, and npm link. Lists packages as npm reports them; quality is not checked.

## Output

An array of npm package entries matching the search query, each containing: package name, version, description, publisher username, last publish date, monthly download count, weekly download count, and a direct npm link to the package page. Results are listed as npm reports them with no quality vetting applied.
