Agents can pay per call past their daily limit
A self-registered agent that reaches its daily compute limit can pay for the next call with a wallet payment and have it run straight away in its own workspace, with no claim and no person.
A self-registered agent workspace has a daily limit on price computations. Until now the only way past it was for a person to claim the workspace.
Where pay per call is offered, the agent can now send the same request again with its own key and a signed x402 payment in USDC at the per-call price. The call runs straight away in the agent's own workspace and does not count against the daily limit. Every other rule of the workspace still applies, including built-in pricing functions only. Paying works on the compute and price router calls; verifying a price still counts against the limit. If a paid call fails, for instance because the function it names does not exist, the agent gets the same answer as an unpaid call and is not charged, and the same payment can be sent again.
When the limit is reached, the refusal now says what to do next: pay for the call, with the price and where to send the payment, or have a person claim the workspace. The discovery documents, the plain-text agent guide, the registration response and the guide for testing with your own agents say the same.
In the dashboard, paid calls show as "Paid per call" in the usage list, and the live traffic view counts them as the agent's own requests. The paying wallet address is recorded on each paid call. Paying never links that wallet to the workspace, so signing in with the wallet later gives no access to it.
