How to call it

curl --request POST --url https://api.apimart.ai/v1/images/generations \
  --header "Authorization: Bearer $APIMART_API_KEY" --header 'Content-Type: application/json' \
  --data '{"model":"veo3.1-lite","prompt":"a modern cliffside villa at dusk","size":"16:9","n":1}'

Submit, keep the task_id, poll GET /v1/tasks/{id} until completed; the response carries the URL and the exact amount charged.
