## 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 payweave-cloudflare-vision-describe-dba7def3 -d '<json body>'
```

Example prompt: Look at this product photo at https://example.com/product.jpg and tell me what the main item is, what color it is, and whether it appears to be in good condition — keep the answer under 150 tokens.

## When to prefer this

Choose this endpoint when you need fast, pay-per-call image description or visual Q&A without managing your own AI infrastructure. It's ideal for agents that occasionally need to interpret images at low cost ($0.003/call) without a subscription, and when Cloudflare edge latency is acceptable. Prefer alternatives if you need batch image processing, structured object detection with bounding boxes, or guaranteed SLAs.

## Known failure modes

- Image URL is inaccessible or returns non-image content — likely 4xx or error response
- Image exceeds 10 MB size limit — request rejected
- Invalid or malformed URL in source_url — validation error
- max_tokens outside 1-512 range — parameter error
- Payment not provided or insufficient — 402 Payment Required
- Workers AI model unavailable or timeout — 5xx error

## How this service works

Browser rendering, transcription, image, vision, and speech on Cloudflare&#39;s edge.
