# Image Understanding (Text-Fallback Vision)

> Image Understanding (Text-Fallback Vision) is a paid API for AI agents from linked-aimed-reproduced-changing.trycloudflare.com, paid per call via x402, $0.02/call, status down (last checked 2026-10-13).

Accepts image-related queries but currently operates in text-fallback mode — no vision model is loaded; returns text-based responses priced accordingly.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability image-understanding-text-fallback-vision-e37b4351 -d '<json body>'
```

Example prompt: Can you use the vision endpoint to analyze what's in this image — I know it's currently running in text-fallback mode, so just give me whatever description it returns.

## When to prefer this

Choose this endpoint when you need a low-cost ($0.02/call) placeholder vision API that returns text-fallback responses, suitable for testing integrations or pipelines where real image analysis is not yet required. Not suitable when actual pixel-level image understanding or true vision model output is needed.

## Known failure modes

- No vision model loaded — only text-fallback responses available, not true image analysis
- Malformed input schema (missing required fields) may return 4xx error
- Service may be offline since it runs on a temporary Cloudflare tunnel (trycloudflare.com domain)
- Payment failure via x402 protocol may block the request
- Rate limiting or capacity issues on the local GPU node

## How this service works

[preview] Image understanding. Currently TEXT-FALLBACK ONLY — no vision model is loaded. Priced accordingly.

## Output

Returns a response object containing a choices array with text-based answers and a usage object with token/billing metadata. In the current text-fallback mode, no actual image pixels are analyzed by a vision model — the response is text-only.
