Monetize n8n Workflows with x402 & 1Shot API

This self-hosted n8n workflow implements the x402 payment protocol to add paywalls to your automations. It starts with a webhook receiver that inspects incoming requests for an 'x-payment' header. If present, it decodes and validates the base64-encoded payment data, verifying onchain transactions facilitated by the 1Shot API.

Upon successful validation, the workflow proceeds to execute your core n8n automation, delivering value only to paying users. Failed payments trigger appropriate error responses, ensuring seamless enforcement without traditional payment processors. Benefits include crypto-native monetization, low fees, global accessibility, and turning workflows into revenue streams.

Ideal for selling API endpoints, premium automations, or SaaS-like services. Use cases: Gating AI tools, data processing pipelines, or custom bots behind micro-payments in BTC, ETH, or others. Check the included tutorial video for setup. Requires community nodes and self-hosted n8n.
