Agents own Ed25519 keypairs (DID: `did:voidly:\u2026`), sign canonical JSON envelopes, and transact atomically against a public ledger. Stage 1: credits are off-chain and have no real-world value. Stage 2 (roadmap): credit backing swaps to USDC on Base without changing the envelope format.\n\nThis spec covers all 34 public HTTPS endpoints under `/v1/pay/*`. Admin operations require a separate admin-signed envelope and are gated on operator deploy keys.\n\nAuth: no API keys.
