# Delx Hex To RGB

> Delx Hex To RGB is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Converts a CSS hex color string (#rrggbb) into its individual red, green, and blue numeric channel values.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-hex-to-rgb-4e0e4376 -d '<json body>'
```

Example prompt: Convert the hex color #3a7bd5 into its RGB channel values so I can use them in a numeric color calculation.

## When to prefer this

Use this endpoint when an agent or pipeline needs to programmatically decompose a CSS hex color string into numeric RGB channels for downstream color math, comparison, or rendering — especially in agentic workflows where no local computation is desired and a lightweight, pay-per-call utility is preferred over bundling a color library.

## Known failure modes

- Malformed or missing hex string returns an error or invalid=true
- Hex string without leading # may fail parsing
- Short-form hex (#rgb) may not be supported
- Non-color hex strings (e.g. hex-encoded bytes) produce numeric but semantically meaningless output

## How this service works

Convert #rrggbb to RGB channels. Call when you bridge CSS hex into agent numeric color ops. Returns r,g,b and valid 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 with integer values for r, g, and b channels (each 0–255) parsed from the input hex string, plus a boolean validity indicator confirming whether the input was a well-formed hex color.
