Inputs

Name	Type	Description
`package` (required)	string	PyPI package name

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://tools.funwords.eu/pypi?package=requests"

Or one of your 25 free calls, no key:

curl "https://tools.funwords.eu/pypi?package=requests&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.

Questions

Does it report vulnerabilities?

No. /package and /package-audit add risk flags and advisories.

How do I pay?

Each successful call costs $0.01; failed calls are not charged. The first 25 calls are free. Then pay with card credits (from $1; the key goes in an Authorization header or, for clients that can only fetch a URL, as api_key= in the URL) or per call in USDC over x402 or MPP. No account is needed.
