Autlantic BillingUSDC on Base

TypeScript, Python, and Go server SDKs plus iOS/Android Checkout. Hosted API for USDC subscriptions, one-time payments, and payment links. Non-custodial settlement to your EVM wallet.

Server SDKs

Node (npm), Python (PyPI), and Go. Subscriptions, payment links, webhooks. Same hosted Billing API.

Mobile Checkout

iOS (SPM) and Android present hosted checkoutUrl. No API keys in the app.

Hosted API

REST with API key for any stack. OpenAPI, Autlantic-Version pin, Test and Live keys.

Payment links

Fixed-amount shareable URL and QR. Payer opens hosted checkout; USDC settles to your wallet.

Ways to integrate

Mode	Best for
npm SDK	Node backends, in-process sandbox, full control
Hosted HTTP API	Any server stack (curl, Python, Go, PHP), API key only
Mobile Checkout	iOS / Android apps: open `checkoutUrl`; no API keys in the app (guide)
