| Name | Type | Default | Allowed | Description |

Put exact text in quotes and name the lettering style. |

| quality | enum | medium | very_low · low · medium · high | Render quality and price tier. Use medium for most edits, high for print-grade detail. |
| seed | integer | — | 0–2147483647 | Random seed (0 to 2147483647) for reproducible results. Omit for a new variation each run. |
| enable_copyright_detection | boolean | false | — | Runs a post-generation copyright check (adds latency). Leave off unless flagged images must be withheld. |
File inputs (image: one image url · mask: one image url · reference_images: up to 4 image urls) take URLs. Upload the raw file to POST /v1/uploads with its own Content-Type and pass the url it returns. Inputs are kept 90 days.
