How L402 Payments Work
L402 is an open protocol that enables machine-to-machine payments using Bitcoin's Lightning Network. No accounts, no API keys — just instant micropayments.
Request Data
Make an API request to any data source. If payment is required, you'll receive a 402 Payment Required response with a Lightning invoice.
Pay with Lightning
Pay the Lightning invoice using any Bitcoin wallet. The payment is instant and costs only a few satoshis per request.
Receive L402 Token
After payment, you receive a cryptographic token (L402) that proves your payment and grants access to the data.
Access Data
Include the L402 token in your request header. The gateway verifies the payment and returns your data instantly.
