How this service works
Seeded Color Hex: Seeded Color Hex selects a reproducible display color without claiming accessibility from bounded caller-supplied values without an external provider. Call Seeded Color Hex when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Color Hex as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, state…
Output
Returns a JSON object containing a hex color string (e.g. '#671c49'), an accessibility_checked boolean, a status field ('pass'), and evidence metadata including whether input was retained (always false), an SHA-256 hash of the input, and external call count (always 0).
Example use cases
Consistent avatar background colors
“Give me a hex color for the seed 'alice@example.com' so I can use it as her avatar background — it needs to be the same color every time.”
Color-coding product category labels
“I need a stable hex color code derived from the slug 'electronics-accessories' to use as a label color in my UI.”
Assigning team colors by name
“What hex color does 'Team Phoenix' map to? I want every mention of that team to show the same consistent color across my app.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/seeded-color-hexWhen to prefer
Choose this endpoint when you need a fast, deterministic, seed-reproducible hex color with zero side effects and no external dependencies — ideal for UI avatar colors, tag labels, or any scenario where the same input must always yield the same color. Prefer it over random color generators when consistency across sessions matters.
Side effects
- Seed exceeds 8192 character limit — request rejected
- Missing or empty seed field — may return error or unexpected result
- Network timeout on the Delx API — no result returned
- Invalid JSON body — 400 error
