# Relaystation Image Metadata

> Relaystation Image Metadata is a paid API for AI agents from api.relaystation.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Reads and returns dimensions, format, and EXIF presence for an image URL before processing

## Facts

- Endpoint: POST https://api.relaystation.ai/v1/image/metadata
- Price: $0.01/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 relaystation-image-metadata-044f94d8 -d '<json body>'
```

Example prompt: Before I resize it, can you check the dimensions, format, and whether EXIF data is present for this image: https://example.com/photo.jpg?

## When to prefer this

Choose this endpoint when you need a lightweight, cheap pre-flight check on an image before committing to heavier processing (resizing, conversion, OCR). It is ideal when you only need dimensions, format, and EXIF presence — not pixel-level analysis or content understanding. At $0.0005/call it is the lowest-cost way to gate downstream image workflows.

## Known failure modes

- Invalid or inaccessible image URL returns an error
- Unsupported image format may not return all fields
- Network timeout if remote image URL is slow to respond
- Non-image URLs (HTML pages, PDFs) will fail or return partial data

## How this service works

$0.0005/call. Read dimensions, format, and EXIF presence — inspect before you process. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny

## Output

Returns the image's pixel dimensions (width and height), file format (e.g. JPEG, PNG, WebP), and a flag indicating whether EXIF metadata is present in the image.
