What you saw
Why it happened
Manifest keys always start withmnfst_. Your token has a different prefix, which almost always means a provider key (OpenAI, Anthropic, etc.) got pasted into the wrong field.
How to fix it
- Open the dashboard and copy your agent’s key. It looks like
mnfst_xxxxxxxxxxxx. - Replace the token in your client’s config and retry.
- Provider keys (OpenAI’s
sk-..., etc.) belong on the Routing page, not in the Authorization header.
