How this service works
IMAGE DESCRIPTION (vision AI) — POST {url} or {image_base64} and get back what is IN the image: a detailed description, notable objects, visible text transcribed, colors, and style. Or ask a specific {question} about the image ('what error is on this screen?'). PNG/JPEG/GIF/WebP up to 5 MB. For agents without eyes: alt text, screenshot triage, image search and moderation. Fast vision model; the x402 payment IS the auth.
Output
Returns a detailed natural-language description of the image including notable objects, any visible text (transcribed), dominant colors, and visual style. If a specific question was asked, it answers that question directly. Useful for alt text generation, screenshot triage, content moderation, and image search indexing.
Example use cases
Example prompt
“Look at this screenshot and tell me what error message is on the screen — here's the image URL: https://example.com/screenshot.png”
Technical details
Endpoint
POSThttps://api.webbersites.com/api/describe-imageWhen to prefer
Choose this endpoint when you need to understand the content of an image — extracting visible text, identifying objects, generating alt text, triaging screenshots, or answering specific visual questions. Ideal for agents that lack native vision capabilities and need to interpret images from URLs or base64 data. Payment via x402 serves as auth, so no API key management is needed.
Side effects
- Image URL unreachable or returns non-image content — request fails with error
- Image exceeds 5 MB size limit — rejected
- Unsupported format (e.g. TIFF, BMP) — rejected
- Ambiguous or low-resolution image may yield vague descriptions
- Network timeout fetching remote image URL
