## 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-info-3a9ae0fb -d '<json body>'
```

Example prompt: What version, license, and repository does the 'requests' package on PyPI have?

## When to prefer this

Use this endpoint when you need quick, structured metadata about a specific package on npm, PyPI, or Cargo — especially version, license, and repository — without needing vulnerability scan data or deep security analysis. It is a lightweight, low-cost ($0.002 USDC) lookup suitable for dependency auditing, license compliance, or enriching package references in documentation or pipelines.

## Known failure modes

- Package not found in the specified ecosystem — returns error or empty response
- Invalid ecosystem value (not npm, pypi, or cargo) — schema validation error
- Package name typo leads to not-found response
- Payment failure via x402 — call is not charged and not executed
- Rate limit exceeded on free MCP tier (100 calls/day)

## 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 package name, ecosystem, current version, SPDX license string, homepage URL (if any), repository URL, human-readable description, and a list of maintainers.
