> Relaystation Image Adjust is a paid API for AI agents from api.relaystation.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

## Facts

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-adjust-097126c7 -d '<json body>'
```

Example prompt: Take this product photo and increase the brightness by 20, boost saturation by 30, and add a slight warm orange tint to it.

## When to prefer this

Choose this endpoint when you need fast, affordable, single-call image color adjustment — brightness, saturation, hue, lightness, negation, or tinting — without setting up a full image editing pipeline. Ideal for automated workflows that need lightweight color correction at scale at $0.0003 per megapixel.

## Known failure modes

- Invalid or unreachable image URL returns an error
- Out-of-range adjustment values may return a validation error
- Unsupported image format causes processing failure
- Insufficient x402 payment balance returns a payment error
- Large image files may time out or exceed processing limits

## How this service works

$0.0003/MP. Adjust brightness, saturation, hue, lightness — or negate and tint — in one call. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny

## Output

Returns a modified image file with the requested color adjustments (brightness, saturation, hue, lightness, negation, tint) applied. The output is a processed image ready for display or further use.
