How this service works
Color converter + WCAG contrast: Convert hex/rgb/hsl/CSS names to hex, RGB, HSL, CMYK; luminance, best text color and WCAG AA/AAA contrast against another color. Free tier 10/day; then $0.001 via x402 (HTTP 402 + PAYMENT-REQUIRED) or X-API-Key credits. Not charged on failure. $0.001 USDC per call via x402 on Base. Run by MoneyTools.
Output
A JSON object containing the input color expressed in hex, RGB, HSL, and CMYK formats; its relative luminance; the recommended best-contrast text color (black or white); and WCAG AA and AAA pass/fail results plus numeric contrast ratio against the optional second color. Also includes payment metadata indicating whether a charge was applied, the network, and the transaction reference.
Example use cases
Accessibility audit for brand colors
“Does our primary brand color #2d6a4f pass WCAG AA contrast when used as text on a white background? Also give me the full RGB and HSL values.”
Design token format conversion
“I have a color defined as rgb(26, 115, 232) — can you convert it to hex, HSL, and CMYK so I can add it to our design system?”
Pick readable text color for a background
“My card background is #1e1e2e — what's the best text color to use on it, and what contrast ratio would that give me?”

Endpoint
GEThttps://tools.moneytools.dev/v1/color?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need color format conversion (hex↔RGB↔HSL↔CMYK) combined with WCAG accessibility analysis in a single call, especially in automated design pipelines, accessibility audits, or agent workflows that need to validate UI color choices. It's particularly useful when you need luminance and best-text-color recommendations without running a full design tool. The x402 micropayment model makes it viable for low-volume or one-off agent calls without subscription overhead.
Side effects
- Invalid or unrecognized color string returns an error — unparseable inputs like malformed hex or unknown CSS names
- Missing required 'color' query parameter returns a validation error
- Free tier exhausted (10 calls/day) without payment method triggers HTTP 402 requiring x402 micropayment or API key
- Network or service downtime returns 5xx; no charge on failure
