Checking a saved proof is free, forever, and rate-limited per plan — reuse is the point of a portable
proof. You pay only when you create a new proof. Creating one depends on the selected verifier; the
current price is shown before a billable verification runs. The credit weight for each verifier is
returned by GET /api/v1/payments/pricing, which lists every check's credit cost.
Buy credits at any time from your profile. Card top-ups start at 200 credits. Suggested packs are 5,000 and 10,000 credits. Purchased credits never expire.
| Option | Who pays | Use it for |

| Listing checkout | The user | Paid content, services, or access. |
| Pay per call | The caller | Agents and APIs that pay for each request with x402. |
Turn on visitor checkout in the gate's pricing step. For card payments, connect a payout account once under Payouts. Until payouts are connected, paid gates accept USDC only. Payment runs after verification by default. Gate checkout
Agent setup creates two separately signed proofs. Each is billed to its signer unless a validated sponsor or pay-per-call proof applies.
| Step | Default payer |
|---|---|
The agent signs agent-identity |
The agent's account |
The owner signs agent-delegation |
The approving account |
| Your server signs with its own profile | Your builder profile |
| A valid sponsor grant | The sponsoring organization |
| A valid pay-per-call proof | The caller that paid |
Billable calls return 402 with a quote. Add credits, or pay for the call with x402 and retry with the PAYMENT-SIGNATURE header.
