Shipped toll-booth - L402 middleware that turns any HTTP API into a Lightning paywall. Five backends (Phoenixd, LND, CLN, LNbits, Alby). Three payment rails (Lightning, Cashu, NWC). Runs on Express, Deno, Bun, and Cloudflare Workers. Cashu-only mode means you can gate a serverless API behind payments with zero Lightning infrastructure. Already running in production gating a Valhalla routing engine at routing.trotters.cc. npm install @thecryptodonkey/toll-booth https://github.com/TheCryptoDonkey/toll-booth
