Technical details
Endpoint
POSThttps://apex-api-gamma.vercel.app/api/ai/image/describe?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically generate a natural language description of an image — for example, to create alt text, moderate content, extract visual information, or feed image context into a downstream AI pipeline. Prefer this over general-purpose vision APIs when you want a pay-per-call model with no API key setup required.
Side effects
- Invalid or inaccessible image URL returns an error
- Unsupported image format may fail to process
- Payment failure (402) if USDC balance is insufficient
- Timeout for very large or slow-loading images
- Ambiguous or empty query may yield generic descriptions
