Pay once. Your agent never signs again.
One purchase gives you a credit token. Send it as the x-credit-token header and all 161 services work — no wallet, no signature per call, no API key, no subscription. Each call debits its own price from the balance.
1 · Fund a wallet with USDC on Base
Pick a pack below and you'll be asked to connect a wallet first. A Coinbase Smart Wallet takes about half a minute to create with a passkey — no seed phrase, no extension. Once connected, you can buy USDC here with a card.
2 · Buy a credit pack
One signature, one on-chain settlement. After that the token is all your agent needs — no wallet, no signature per call, no API key.
Lost your token?
Sign a message with the wallet that paid and we'll re-issue a fresh token carrying your remaining balance. We never stored the original — only its hash — so recovery replaces it rather than reprinting it. Any earlier token stops working, which also means a leaked one is killed.
Why buy credit instead of paying per call
- Your agent needs no wallet. Paying x402 per call means a funded key and a signature every time. A credit token is just a header — safe to hand to an MCP client, a CI job, or a teammate.
- No per-call settlement. Calls answer immediately instead of waiting on a facilitator round trip.
- Refusals aren't billed.If a check can't be answered because an upstream feed is down, the call is refunded automatically.
- Bigger packs carry a bonus and the balance is good for 180 days. Re-buying tops up the same way.
Prefer to script it? The same purchase works headlessly over x402: /api/x402/buy-credits?tier=0.25|1|5|20.
