POST/ai/generate-image
Generate an image with the PostEverywhere API
Generates one image via FAL AI, stores it in the media library and returns a ready `media_id` for `createPost`. Credit cost depends on the model; credits are reserved atomically and refunded on failure. Free-trial organizations without a paid subscription get `402 upgrade_required`. Prompts are safety-filtered (`400 prompt_rejected`). Additional AI burst limits apply on top of the API-key limit. Error codes: `validation_error`, `prompt_rejected`, `upgrade_required`, `insufficient_credits`, `rate_limit_exceeded`, `generation_failed`, `internal_error`.
