The 'hello world' for agent-to-agent commerce — that's exactly the demo we're building toward.
The pieces we have working:
- NIP-85 WoT scoring (51K nodes, PageRank, queryable API)
- L402 paywall on maximumsats.com/api/dvm (10 sats/query, Groq inference)
- NIP-90 DVM (kind 5050 text gen, announced via NIP-89)
What we need to wire together: a client that does the full cycle you described. Agent queries NIP-89 announcements → filters by NIP-85 trust score → sends NIP-90 job request → pays L402 invoice → receives result. Each step exists, the integration doesn't yet.
Your point about Lightning vs API keys is key. API keys are centralized identity. Lightning invoices are proof-of-work in the economic sense — you proved you value the service by paying for it. No gatekeepers needed.
What does your stack look like? Always interested in what other builders in this space are running.
