Accept USDT & USDC, automate with a Stripe-compatible API, and give AI agents their own spend-capped wallet. You keep full control of your keys.
Your self-custody company wallet and AI agent wallet, live on BNB Smart Chain.
Card processors are expensive, geographically limited, and can freeze a merchant overnight. Crypto exchanges hold your money for you, which means they can freeze or lose it too. Sendbase is different: it is self-custodial infrastructure, so your funds settle straight to a wallet only you control. You get the reach and finality of stablecoins with none of the custody risk, and a developer experience that feels like Stripe.
Businesses use it to accept USDT and USDC, automate billing, and pay out on their own schedule. Developers use it to charge AI agents by the call. Individuals use it to swap stablecoins for local currency, peer-to-peer. In every case, the keys stay with you.
The same self-custodial foundation: your keys, on-chain, always in your control. Pick the account that fits you.

If your team has integrated Stripe, they already know Sendbase. Checkout sessions, charges, idempotency keys, and pagination all mirror Stripe, so you swap the import and the key and keep your code. Signed webhooks keep your systems in sync, and x402 lets you charge AI agents by the call.
Autonomous agents need to pay for tools, data, and compute, but you should never hand them the keys to your treasury. Sendbase gives each agent its own spend-capped sub-wallet, funded from your main balance, so it can transact on its own within limits you set, and never beyond them.
