Running examples

x402 / L402 — paid API fetch

These examples fetch a URL protected by an HTTP 402 payment wall. You need an NWC connection string.

NWC_URL="nostr+walletconnect://..." yarn 402      # auto-detects L402 or x402
NWC_URL="nostr+walletconnect://..." yarn x402     # x402 only
NWC_URL="nostr+walletconnect://..." yarn l402     # L402 only

Override the default URL:

URL="https://your-402-endpoint.example.com" NWC_URL="nostr+walletconnect://..." yarn 402

Lightning Address — request invoice

Fetches LNURL-pay data for a lightning address and requests an invoice. No credentials needed.

yarn request-invoice

Zaps via NWC

Sends a zap to a lightning address using NWC for payment and a Nostr key for signing.

NOSTR_PRIVATE_KEY="your-hex-private-key" NWC_URL="nostr+walletconnect://..." yarn zaps-nwc
