How this service works
Convert RGB channels to #rrggbb. Call when you bridge agent RGB pickers to CSS hex. Returns hex and channels for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns a JSON object containing the hex color string in #rrggbb format (e.g. #ff6347) and the original red, green, and blue channel integer values that were used to produce it.
Example use cases
CSS styling from color picker
“I picked a color in my design tool and it gives me RGB 72, 199, 142 — what's the hex code I can drop straight into my CSS?”
Agent UI theme color bridging
“My agent's UI sends color choices as RGB tuples. Convert RGB 30, 144, 255 to a hex string so I can use it in the HTML template.”
Brand color cross-format lookup
“Our brand red is RGB 220, 38, 38. What's the equivalent hex color code I should use in the stylesheet?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/rgb-to-hexWhen to prefer
Choose this endpoint when your agent receives RGB channel integers from a color picker, sensor, or design tool and needs a CSS-ready #rrggbb hex string with no additional dependencies, API keys, or external network calls. It is purpose-built for lightweight, stateless color conversion in agentic pipelines where simplicity and low cost ($0.001 USDC) matter more than a full-featured color library.
Side effects
- Missing one or more of r, g, b fields returns a 4xx validation error
- Channel values outside 0–255 integer range may return an error or unexpected result
- Non-integer (float or string) channel values may fail schema validation
- Network or service downtime returns a 5xx error
- Insufficient USDC balance or x402 payment failure results in a 402 Payment Required response
