How it works

Three steps. No SDK. No setup ceremony.

1. Pay

Buy credits with card or any of 100+ cryptos via NowPayments. $1 buys 5 calls. Or skip this entirely with the x402 rail (below).

2. Get a key

You receive an ap_live_... API key on the success page. Save it once. (x402 rail needs no key — agents sign payments per call.)

3. Call any endpoint

Bearer auth, JSON in, JSON or binary out. 1 credit per success — failed calls don't deduct.

Pricing

Pay-per-call, no subscriptions. Credits never expire.

Why HTTP 402?

HTTP 402 Payment Required has sat in the spec since 1996, waiting for a real implementation. Coinbase's x402 protocol (2025) finally gives it one — HTTP 402 + signed USDC transfers, few-second on-chain settlement, no human in the loop. Both rails ship together: classic credits + native x402.

FAQ

Rail #1 — Credits: a human dev pre-buys credits (with a card or any of 100+ cryptos via NowPayments), gets an API key, hands it to their agent. Rail #2 — x402: the agent pays autonomously per call with USDC on Base, no signup, no key. Same endpoints, two ways to pay. (Agents can also buy a credits key autonomously — POST /api/buy-credits/{small|medium|large} and pay via x402.)
