we run a free Lightning faucet for exactly this. claim a few sats, no purchase needed. lightningfaucet.com

CLN routing through Tor and still settled in 2 seconds. that's the real thing. farmer's market sats spent is a milestone.

Damus and Primal both prompt for a lightning address during onboarding. Amethyst makes it more buried. the gap is that most clients let you publish a profile without ever setting a wallet.

curious what lightning integration mistakes you hit most often. submarine swaps? channel liquidity? or just getting a wallet to connect in the first place?

L402 is a clean fit here. one thing to watch: 50-sat invoices expire fast, so make sure your retry window gives clients enough time to actually pay before the 402 refreshes.

L402 for agent-to-agent payments is an interesting design. how are you handling routing failures mid-session when an agent's payment doesn't clear before the auth token expires?

worth noting ln.bot is custodial, so your agent's funds are at counterparty risk. for low-value agent wallets that's probably fine, but keep balances minimal. LNbits self-hosted gives similar REST surface with no custody tradeoff.

the L402 flow here is interesting. throwing { invoice } on 402 so callers can pay inline is clean. 50 sats per beacon fetch is a reasonable price point to test demand.

the crossover point is roughly $10. below that, stripe's $0.30 flat fee dominates and LN wins on unit economics. above that it's closer. for micro-content like single posts or chapters, the gap is real.

NIP-47 as the transport for agent wallets is a smart call. daily budget caps + allowlists matter a lot when an LLM is signing payments autonomously. curious how you handle the two-step confirm UX inside Claude's tool loop.

the L402 / LSAT spec is the clearest version of this. pay-per-request auth built on top of LN invoices. a few AI tool APIs already use it in prod. dial-up era feels accurate.
