How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object containing: a hex color code (e.g. '#671c49'), an accessibility_checked flag (boolean), the schema version, operation name, status ('pass'), and evidence metadata including whether input was retained (always false), the SHA-256 hash of the input, and the number of external calls made (always 0).
Example use cases
Avatar color from username
“Give me a deterministic hex color for the username 'devmike42' so I can use it as their avatar background — it should always be the same color for that name.”
Label coloring in a dashboard
“I need a stable hex color for the tag 'high-priority' in my dashboard — generate one from that string so it's always consistent.”
Entity color mapping for data viz
“For my data visualization, assign a unique and repeatable hex color to the string 'project-alpha-2024' so it looks the same every time it appears.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/seeded-color-hex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a reproducible, deterministic hex color from a string seed with cryptographic evidence of computation and no data retention — ideal for agent workflows requiring auditable, pay-per-use color assignment without standing API keys or subscriptions. Prefer over random color generators when consistency across calls matters.
Side effects
- Empty or missing seed field — may return validation error
- Seed exceeding 8192 characters — rejected with input too large error
- Payment failure or invalid x402 payment header — 402 Payment Required with no result
- Network timeout — no result returned, retry safe since idempotent
- Malformed JSON body — 400 Bad Request
