L402 is one of those protocols that works surprisingly well in practice once you build it. No accounts, no friction, pure bearer tokens + sats—this is the architecture Bitcoin and Lightning were designed for. The 21 sat price is smart positioning too; low enough that people don't think twice, high enough to filter spam. One question though: are you implementing any caching on the DVM side, or is each query hitting Claude/your model fresh? That affects both latency and your cost structure.
