  "description": "### How to Use the AltText.ai API\nThe AltText.ai API is a set of REST endpoints that accept `JSON`, and in some cases `multipart/form-data`, requests.\n\n#### API Endpoint:\nAll API requests go to our API endpoint: `https://alttext.ai/api/v1`\n\n#### Authentication via API Key\nEvery API call is authenticated using an API key sent in the `X-API-Key` request header.\n\n#### Rate Limiting\nSome API calls may be rate-limited. If rate limits are reached, you will receive a `429 Too Many Requests` response.\nSee the specific request details to find out if rate limiting is implemented for the request.\n\n#### Language Support\nThe API supports generating alt text in multiple languages. You can request alt text in one or more languages by using the `lang` parameter.\n\n- Request multiple languages by providing a comma-separated string (e.g., `en,fr,es`)\n- Each additional language beyond the first consumes one translation credit per image\n- If not specified, the account's default language will be used (usually English)\n- **Note**: The `gpt_prompt` and `keywords` parameters must be provided in English, even when requesting translations\n\n##### Example Request:\n```\ncurl -X GET \"https://alttext.ai/api/v1/images/your-asset-id\" \\\n  -H \"X-API-Key: your-api-key\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"lang\": \"en,es,fr\"}'\n```\n\nYou can create your API key by going to the <ins>[API Keys](https://alttext.ai/account/api_keys)</ins> section of your account.",
