Tools
| Tool | Description | Behaviour |
|---|---|---|
| add_watermark | Stamps text (e.g. "© Your Brand") on an image in a corner, the centre, or tiled diagonally. Without an API key: returns a free watermarked preview (≤700px) plus unlock_url, which a human opens to download the full-resolution file for site credits (then call get_result). With an API key (Authorization: Bearer stb_…): returns download_url for the full-resolution file directly and charges the key owner's credits when the job starts, refunded automatically if processing fails. Retrying a call creates and charges a new job — use get_result to fetch an earlier one. | Changes data |

Rates are 2026 estimates and vary by region; pass fee_rate_percent to override. Currency-agnostic. Free. | Read-only |
