## 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 datakoot-package-downloads-e976796a -d '<json body>'
```

Example prompt: How many downloads did the 'express' package get last month on npm?

## When to prefer this

Use this endpoint when you need a quick, single-call lookup of last-month download statistics for a specific package in npm, PyPI, or Cargo. It is ideal for popularity checks, dependency vetting, and trend monitoring without requiring a registry API key. At $0.002 USDC per successful call it is cost-effective for spot checks; use the free MCP tier (100 calls/day) for light workloads.

## Known failure modes

- Package not found in the specified ecosystem — returns error or empty result
- Invalid ecosystem value supplied (not npm, pypi, or cargo) — validation error
- Misspelled or non-existent package name — no data returned
- Payment failure via x402 — call is not charged and no result returned
- Registry data temporarily unavailable — upstream timeout or error

## 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 ecosystem name (e.g. 'npm') and the integer count of downloads in the last calendar month (e.g. {"ecosystem":"npm","last_month":738139197}).
