FAQ

What cryptocurrencies do you accept?
We accept ETH, USDC, USDT, DAI, WETH on Ethereum, Polygon, Arbitrum, Base, and Optimism. We also accept SOL and USDC-SPL on Solana. Recommended: USDC on Base (lowest fees, ~$0.01 per tx).
Do I need KYC or identity verification?
No. We accept crypto payments with no identity verification required. Just an email address for your API key.
How is payment verified?
After sending payment, submit your transaction hash via our /payments/verify-tx endpoint. We verify the transaction on-chain across all supported networks automatically. Your API key is upgraded instantly upon verification.
Can AI agents pay for themselves?
Yes. Our entire payment flow is API-first. An AI agent can POST to /payments/create, send crypto, then POST to /payments/verify-tx with the tx hash. Fully automated, zero human interaction needed.
What happens if I exceed my daily limit?
Requests beyond your daily limit return HTTP 429. Your counter resets at midnight UTC. Upgrade to a higher tier for more capacity.
