100,000 signed writes free. After that, top up in USDC on Base or Ethereum and keep going. Signed usage receipts, no invoices, no seat contracts, no minimum term.
How it works
→ Free — every account starts with 100,000 free signed writes (Protected Flow assessments, R3Pv vectors, receipt-relay events, evidence exports).
→ Grace — after the 100,000th write, the next 5,000 keep working with a top-up nudge on each response. No hard stop yet.
→ Paused — once grace is exhausted, further writes return HTTP 402 with a top-up address, amount, and memo.
→ Active paid — send USDC to the treasury address on Base or Ethereum. The indexer credits within one confirmation, state flips, next write goes through. No email, no ticket, no invoice.
One write = one canonical, Ed25519-signed, replay-safe receipt of an agentic action. Priced per receipt, not per API call, not per transfer, not per dollar moved.

Create a top-up intent
Pick a chain and an amount. You'll get a treasury address and a memo. Send USDC on that chain; the indexer credits your account within one confirmation (typically 1–2 minutes).
Minimum $10. At default $0.010/write, $10 buys you 1,000 writes.
