How this service works
Call when an agent needs hex colors extracted from text, capped at 20 matches. An empty match list is billed. No network. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/regex-hex-color first.
Output
Returns a list of up to 20 hex color code strings found in the input text, matched via regex. If no hex colors are present, an empty list is returned — but the call is still billed at $0.002 USDC.
Example use cases
Pull palette from CSS source
“I have this CSS file content and I need to know every hex color used in it — can you scan it and list all the hex codes? Here's the text: 'h1 { color: #333333; } a { color: #0066CC; } .highlight { background: #FFDD00; }'”
Extract colors from design token file
“Here's a raw design token file with a bunch of color definitions mixed into other text — can you pull out just the hex color codes for me? The content is: 'primary: #2D3E50, secondary: #E74C3C, accent: #1ABC9C, neutral: #95A5A6'”
Find hex codes in marketing copy
“I need to find any hex color codes embedded in this HTML email template text so I can audit the brand colors used — can you extract them all? The template snippet is: '<td style="background:#004080"><font color="#FFFFFF">Sale!</font></td>'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/regex-hex-color?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, no-network regex extraction of hex color codes from text and are willing to pay $0.002 USDC per call. Prefer the free POST /v1/sandbox/regex-hex-color endpoint first if available. Choose this over general-purpose LLM color parsing when you need deterministic, regex-exact matching rather than approximate extraction.
Side effects
- Empty match list returned when no hex colors are present in text — still billed
- Input text exceeds 100,000 character limit — request rejected
- Missing or empty 'text' field — validation error
- More than 20 hex colors in text — only first 20 returned, remainder silently truncated
