A crypto payment API you host and own.
Under every integration is the same API. My Crypto Server exposes a REST API and a TypeScript SDK for creating charges and reading payment state, plus signed webhooks on confirmation. It's the primitive you build any custom checkout on, and you host all of it.
REST API + TypeScript SDK + HMAC-SHA256 signed webhooks.
Integration
Push the app to Vercel, attach any Postgres database, add your Alchemy key, and point it at your wallet. You're live in about an hour.
POST a charge for the order amount and get back a checkout URL and id. Register your webhook endpoint to receive a signed event the moment the payment confirms.
On a confirmed payment, the server sends a signed webhook to your endpoint. Verify the signature, then mark the order paid and fulfil, idempotently.
Test with the live demo flow, then flip it on. Card options can stay exactly where they are; crypto simply runs alongside them at 0% fees.
Create charges and read payment state from a TypeScript SDK or the REST API. The same primitives power the dashboard, so anything the UI does, your code can too.
Every confirmed payment fires an HMAC-SHA256 signed webhook with replay protection, so your app marks orders paid idempotently and never trusts an unverified event.
The customer picks their chain and coin at checkout; your code just creates a charge in USD. Native coins plus USDC, USDT, and DAI are all handled server-side.
Payments derive from your own wallet and settle straight to you. There's no processor balance, payout schedule, or account anyone can freeze.
Create charges, fetch their status, and receive signed webhooks on confirmation. The same primitives power the dashboard, so your code can do anything the UI does.
Yes. Webhooks are signed with HMAC-SHA256 and timestamped with replay protection, and delivery is idempotent, so you can trust and safely retry them.
No. Payment detection runs through Alchemy Notify, so there's no node or long-running watcher process to operate.
