Aperture

Aperture is an implementation of L402s as a reverse HTTP proxy.

Aperture is a reverse proxy that acts as a payment and authentication gateway for Lightning Network powered APIs. It can handle gRPC requests over HTTP/2 as well as REST over HTTP/1 and 2.

Aperture implements both the L402 as well as the MPP specifications.

Aperture receives incoming connections, verifies the validity of the L402 and either forwards the request to the appropriate end point, or obtains a Macaroon and sends it together with a Lightning invoice and the HTTP status code 402 Payment Required.

Aperture is currently used in production in Lightning Loop and Pool.

Aperture includes a Model Context Protocol (MCP) server that makes it convenient for agents to control Aperture natively.
