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 with the package name, resolved version, ecosystem, a list of direct dependencies (each with name, optional flag, and version requirement string), and counts for direct, required, dev, and build dependencies.
Example use cases
Auditing a Python library's dependencies
“Can you look up the direct dependencies for the requests package on PyPI, latest version? I want to know what it pulls in and how many are required vs optional.”
Checking a Node.js package before adopting it
“Before I add express to my project, can you pull up its direct npm dependencies so I can see what it brings along?”
Inspecting a Rust crate for supply chain review
“I'm doing a supply chain review — can you fetch the direct dependencies for tokio version 1.36.0 on Cargo and tell me how many are required versus optional?”
Technical details
Endpoint
POSThttps://x402.datakoot.com/api/package_dependencies?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, machine-readable dependency data for a specific package across npm, PyPI, or Cargo registries — especially when you want direct dependency counts broken down by type (required, optional, dev, build). Prefer this over scraping registry websites or using language-specific CLI tools when you need a uniform API across ecosystems. The per-call x402 micropayment model means no API key setup is required.
Side effects
- Package not found in the specified registry — returns error or empty result
- Invalid ecosystem value (not npm, pypi, or cargo) — validation error
- Specified version does not exist — version not found error
- Malformed package name — registry lookup failure
- Network or upstream registry timeout — service unavailable error
- Payment failure via x402 — call not charged, no result returned
