Buy one call wallet → API
Pay in the browser, get the JSON
Pick an endpoint and press sign & fetch. Your wallet signs one off-chain USDC authorisation for the exact price the server quotes; the facilitator settles it and the data renders below. No npm install, no account, and your key never leaves the wallet. Choose a licence to get a 30-day Bearer token back in the same response.
Response
- What you sign. An EIP-3009 transfer authorisation for exactly the quoted amount, valid for five minutes. It costs no gas and moves nothing until the facilitator submits it.
- Which chains. The page uses the network your wallet is already on if the server accepts it — Base, Polygon, Arbitrum or Avalanche.
- Reusable access. The two licence rows pay once for 30 days — 1,000 calls for $99, 10,000 for $399 — and the signed Bearer token comes back on this page. Send it as
Authorization: Bearer <token>on any paid endpoint.
