Fuse keys
A project can hold more than one Fuse key. Starter allows 3 per project. Team allows 10. Each key has its own per-minute limit. Revoking a key takes effect within about 15 seconds.
The label is only for the dashboard. The proxy does not read it. Copy the two lines when the key is created:
FUSE_BASE_URL=https://fuse.ospalabs.com/v1 FUSE_API_KEY=fz_...
Keys on the same project share the ceiling and the provider keys. They do not share the per-minute counter. Use a separate key for each service so you can revoke one without stopping the others.
Starter is 300 requests per minute per key. Team is 1,200. The limit is counted on the Fuse key, before the provider is called. A 402 from the ceiling still counts as a request against that minute.
