L402 Tool APIs (pay-per-call)​

In addition to one-time guide purchases, Lightning Enable runs paid utility APIs that agents call repeatedly:

EndpointPurposePrice
POST /api/l402/tools/extractURL → clean Markdown (Mozilla Readability)5 sats / call
GET /api/l402/tools/convertUSD ↔ BTC ↔ SATS at live multi-source rate1 sat / call
GET /api/l402/tools/decode-bolt11Parse a BOLT11 Lightning invoice1 sat / call

Each endpoint returns 402 with a Lightning invoice and macaroon; pay it and retry with Authorization: L402 {macaroon}:{preimage}.
