How this service works
Pay-per-call utility APIs for AI agents, settled in USDC via the x402 protocol.
Output
A JSON object containing the base color, mode, seed, count, and an array of color objects each with hex, HSL (hue, saturation, lightness), and RGB (red, green, blue) values.
Example use cases
Brand palette from company name
“Generate a consistent color palette for our company 'Verdant Labs' using the company name as a seed — I want 5 harmonious colors in analogous mode, each returned in hex, RGB, and HSL so I can use them across our design system.”
Complementary colors for UI theming
“I'm building a dashboard UI and my primary button color is #E11D48 — can you find me a complementary color scheme with 4 colors in hex, HSL, and RGB so I can set up proper accent and background theming?”
Monochromatic scheme for landing page
“I need a monochromatic palette based on #10B981 for a landing page redesign — give me 6 shades in that mode with all the hex, RGB, and HSL values so my developer can plug them straight into the CSS variables.”
Technical details
Endpoint
POSThttps://x402.nichospt.net/color-palette?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need programmatically generated, color-theory-correct palettes from a known base color or a deterministic seed string, especially for branding, UI theming, or design systems. Prefer over manual color picking when consistency and harmony modes (analogous, triadic, complementary, etc.) are required. The seed feature is ideal when you want the same palette every time for a given brand or identifier.
Side effects
- Invalid hex color format returns validation error
- Mode not in allowed enum values returns 400
- Count outside 2–10 range returns validation error
- Both base and seed omitted may return default or error
- Payment failure via x402 returns 402 Payment Required
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| base | string | Base hex color, e.g. '#3B82F6'. Drives color-theory harmony. |
| mode | string | |
| seed | string | Any string (brand name, id). Hashed into a deterministic base color — same seed always yields the same palette. |
| count | integer |
