Cest developers

The SDK for each layer.

Use the documented ArcenPay packages for browser UI, trusted backend operations, and autonomous agents.

React: provider, customer identity, ArcenEmbed, and feature hooks.

Node.js: ArcenClient, access checks, payment links, and webhook verification.

Agent: x402 requests, agentic checkout, mandates, and escrow.

Create payment links on the server, not in the React SDK.
