Prepaid credits · every tool · no wallet

One card, every tool.

Buy credits once, get a key, spend it across all 500+ pay-per-call tools and every report - per request, at list price, debited only when a call succeeds. No account, no subscription, no wallet. The card-native twin of paying per call in USDC.

Debited only on a successful call Never expires Secured by Stripe

Your key is shown once on the next page and emailed to you · keep it secret · balance at GET /api/credits/balance · agents with a wallet can skip this and pay per call over x402 / MPP
