What you saw
Why it happened
You set a limit on the agent’s Limits page (say, “$10/day” or “100 messages/hour”), and the current period’s usage just crossed it. Manifest blocks every following request until the period resets or you raise the cap. This is different from M204, which is the Manifest Cloud Free plan monthly request quota, and different from provider 402 errors such as “insufficient credits” from OpenRouter.How to fix it
- Open the dashboard link in the error message. It goes straight to the agent’s Limits page.
- Raise the threshold, change the period, or wait for it to reset. The error message tells you which period was hit.
- Retry the request.
