```

Example prompt: Can you check if white text (#FFFFFF) on a dark blue background (#1A237E) has enough contrast to be readable and accessible?

## When to prefer this

Choose this endpoint when you need a quick, low-cost programmatic check of color contrast between two colors, particularly in automated design pipelines, accessibility audits, or CI/CD workflows where you want to flag potentially inaccessible color combinations without manual inspection.

## Known failure modes

- Invalid or missing color values (e.g. malformed hex codes) may cause processing errors
- Missing foreground or background fields returns an error
- Non-color string inputs may cause unexpected results
- Service may return generic success without detailed WCAG level breakdown
