What you saw

[🦚 Manifest M100] No anthropic API key yet. Add one here: https://app.manifest.build/...
See https://manifest.build/docs/errors/M100
The provider name (anthropic in the example) varies based on which provider Manifest selected.

​
Why it happened

Routing picked a provider that has no key on file for this agent. Manifest won’t silently swap vendors on you, so the request stops here.

​
How to fix it

  1. Open the dashboard link in the error message. It goes straight to the agent’s Routing page.
  2. Either add an API key for the named provider, or remove that provider from your tier configuration so routing won’t pick it again.
  3. Retry the request.
