### Generate Alt Text

**Slug:** `ALT_TEXT_LAB_GENERATE_ALT_TEXT`

Generate accessible alt text for a publicly reachable image URL, optionally guided by language, writing style, SEO keywords, product details, and page context. Each generated result consumes one account credit. Do not retry after a timeout or ambiguous provider failure; check account credits first.

| `style` | string ("descriptive" | "neutral" | "matter-of-fact" | "minimal") | No | Writing style for the alt text; omit to use the account setting. |
| `context` | object | No | Optional page context that can clarify ambiguity but cannot override visible image content. |
| `keywords` | array | No | SEO keywords to include only when natural and consistent with visible image content; inclusion is not guaranteed. |
