Fizzl Buy tools (2, 1 write)

write = sends, deletes, buys or posts
  • x402_buywrite actionFree

    Paid ($0.02 via x402 in USDC on Base, Solana, Algorand or Stellar, or RLUSD on the XRP Ledger, inside the call): say what your agent needs ("weather forecast for Amsterdam tomorrow", "BTC price", "EUR to USD rate") and Fizzl buys the right paid x402 API, the one x402 Doctor has seen paying out day after day at a fair price (up to $0.01), fills in its input, pays it from its own wallet and returns the answer, checked by TypeSafe Jev, with which service it came from and a signed receipt. Nothing is charged when no seller delivers. To see first what it would buy, call x402_pick (free).

  • x402_pickFree

    Free: say what your agent needs and get the paid x402 API that x402 Doctor has seen paying out day after day at a fair price (up to $0.01), with its track record, price and example input, plus alternatives. To buy it in one call, POST https://buy.fizzl.eu/v1/buy {"need": …} ($0.02 over x402): the answer comes back checked, and nothing is charged when no service delivers. Limited to 10 free calls an hour.

What the publisher says

From the Fizzl Buy repository's README, as published. We do not edit it. Read it on GitHub

x402 Doctor

· Live status ·

Diagnoses why an x402-payable endpoint's payment flow is broken, without needing a funded wallet.

Paste a URL (web app) or run x402-doctor (CLI, CI) and get back exactly which check failed, why, and how to fix it. Every check traces back to a real bug hit while shipping PlainText and Ichimoku Signal.

▶ Watch the 70-second explainer (with voice and captions): diagnosing a broken endpoint, the pre-payment check for agents, and the daily Trust Index.

▶ New: the paid fix in 70 seconds: for $0.05 the Doctor hands you the medicine, the exact code that fixes each problem for your stack, in the browser or as JSON for agents.
