Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://tools.funwords.eu/balance/wallet?address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"

Or one of your 25 free calls, no key:

curl "https://tools.funwords.eu/balance/wallet?address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045&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.
