POST/api/v1/logoPay-per-use

Generates a logo mark from your description, in your brand colors. The only metered action on the whole API: first logo free, then credits per logo, independent of plan tier and separate from the unlimited generation endpoints above. See Pricing for credit costs.

Field	Type	Description & options
prompt	Required	What the mark should depict, e.g. "a minimalist mountain peak". No text/letters are ever included in the mark. Up to 2000 characters.

curl -X POST https://api.capci.app/api/v1/logo \
  -H "x-api-key: capci_your_api_key" -H "Content-Type: application/json" \
  -d '{ "prompt": "a minimalist mountain peak" }'
