Per-call USDC billing

Your agent pays for each service call in USDC. Top up once, settle on-chain per call, no shared API keys, no monthly seats.

⛓

Multi-chain settlement, one balance

Send USDC on Base, Solana, or Tempo — auto-credits the ledger in ~30s. Spend it on any service across any chain. The grid routes the payment.
