## 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 fastapi-online-image-crop-26a32a0b -d '<json body>'
```

Example prompt: Crop this image starting at x=50, y=100 with a width of 400 and height of 300 pixels — just send back the cropped PNG.

## When to prefer this

Choose this endpoint when you need a simple, no-signup, pay-per-call image crop operation with crypto payment. Ideal for agents that need to programmatically extract rectangular regions from images on a per-call basis without managing API keys or subscriptions.

## Known failure modes

- Crop coordinates or dimensions out of bounds — returns error if x+width or y+height exceeds image dimensions
- Unsupported file format — only PNG, JPEG, and WebP are accepted
- Missing required parameters — x, y, width, or height not provided returns a validation error
- Payment failure — if USDC payment not included, returns HTTP 402
- File too large — server may reject oversized uploads

## How this service works

Chat, embeddings, OCR, speech-to-text, image editing, image understanding (captioning/Q&amp;A), text-to-speech, translation, writing tools, classification tools, developer tools, local utilities, format/checksum validators, encoding &amp; crypto utilities, date/time calculators, geo/coordinate math, math &amp; finance calculators, novelty tools, and business/social writing generators — 179 endpoints in all, across multiple specialized self-hosted models.

## Output

Returns the cropped image file as binary image data (PNG/JPEG/WebP), containing only the rectangular region specified by the x/y origin and width/height parameters.
