Inputs

Name	Type	Description
`title` (required)	string	Article title
`lang`	string	Language code (default en)

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://tools.funwords.eu/wikipedia?title=Stockholm"

Or one of your 25 free calls, no key:

curl "https://tools.funwords.eu/wikipedia?title=Stockholm&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.

Example result

{
  "title": "Stockholm",
  "description": "Capital of Sweden",
  "extract": "Stockholm is the capital and most populous city of Sweden…",
  "url": "https://en.wikipedia.org/wiki/Stockholm",
  "thumbnail": "https://upload.wikimedia.org/…",
  "licence": "CC BY-SA 4.0",
  "attribution": "Text from the Wikipedia article \"Stockholm\" by its contributors, licensed CC BY-SA 4.0"
}

Questions

Is the full article returned?

No, a short summary: title, one-paragraph extract, description, thumbnail and page URL, with CC BY-SA 4.0 attribution.

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.
