How this service works
62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.
Output
A JSON object with ok:true, the tool name, and a result containing the parsed color in hex, RGB (r/g/b integers 0-255), HSL (h/s/l floats), and optionally a contrast block with the ratio, AA, AAA, and AALarge boolean flags per WCAG 2.1 guidelines.
Example use cases
Accessibility audit for brand palette
“Check if our brand blue #1e90ff passes WCAG AA and AAA contrast requirements against a white background — give me the contrast ratio and compliance status.”
Cross-format color conversion for designer
“I need the RGB and HSL breakdown for the CSS color 'tomato' — can you convert it for me?”
Pick accessible text color for dark background
“Does white text on a #2d2d2d background pass WCAG AA accessibility for normal-sized text? What's the contrast ratio?”
Technical details
Endpoint
GEThttps://x402-toolbox.swiftbotlab.workers.dev/v1/color?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, pay-per-call, no-account color parsing and conversion utility — especially if you also need WCAG accessibility contrast checking in the same call. Prefer it over local libraries when running in a serverless or agent context without a color parsing dependency available.
Side effects
- Unrecognized color string returns an error or ok:false
- Missing required 'color' query parameter causes a 400-level error
- Invalid second color in 'against' param fails contrast computation
- Payment not provided or declined returns HTTP 402
