About the Color Converter API

Color Converter works by analyzing the color provided and converting it to the specified format. It uses advanced algorithms to convert the color to the specified format and returns the color in the new format.

Ways to call it

One endpoint, many ways in — REST with JSON, XML, YAML and CSV, plus GraphQL and an MCP interface for AI agents.

JSON: Default REST response
XML: Markup format
YAML: Human-readable
CSV: Tabular export
GraphQL: Query language
MCP: For AI agents

Other ways to use Color Converter

Same data, same APIVerve account, same credit balance — one key works on all of them.

Give it to an AI agentConnect over MCP and your agent calls it as a native tool — Claude, Cursor, ChatGPT.on VerveKit Google Sheets or ExcelA =VERVE() formula fills a column — no script, no export, recalculates in place.on VerveSheets

Common questions about the Color Converter API.

Read the docs →

What does the Color Converter API do?

Color Converter is a simple tool for converting color formats. It returns the color converted to the specified format.

How do I authenticate Color Converter API requests?

Pass your API key in the x-api-key header over HTTPS. One key works across all 300+ APIVerve APIs — there are no per-endpoint credentials.

How much does the Color Converter API cost?

Each call spends 2 credits from your shared pool. The free tier includes 200 credits every month, and paid plans add more headroom.

How fast is the Color Converter API?

Response time depends on the endpoint — the p50 through p99 latency for this API is published on this page. Requests are served over HTTPS through a global edge network.

What response formats does the Color Converter API support?

JSON by default, plus XML and YAML via the format parameter. GraphQL and an MCP interface for AI agents are available across the catalog.

What HTTP method does the Color Converter API use?

GET over HTTPS, following standard REST conventions with a consistent { status, error, data } response envelope.

Request parameters — GET /v1/colorconverter

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them. Anything not listed here is dropped rather than passed through.

Required

Parameter	Type	Example	Description
`hex`Required	string	`FF0000`	The color in hexadecimal format (e.g., FF0000). Make sure you ommit the #

Example request

1
2

curl "https://api.apiverve.com/v1/colorconverter?hex=FF0000" \
  -H "x-api-key: YOUR_API_KEY"

Authentication

Send your key in the x-api-key header. That is the only auth step — no token exchange, and no per-endpoint scope to configure.

Header	When	Value
`x-api-key`Required	Every request	Your API key. Header names are case-insensitive, so `X-API-Key` is the same header.
`Authorization`Alternate	Instead of the above	`Bearer <key>` — for clients that only expose bearer auth. Resolves to the same account and the same billing.

401 is the only auth verdict

A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.

Response — GET /v1/colorconverter

Every APIVerve endpoint returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape.

Sample response

{
  "status": "ok",
  "error": null,
  "data": {
    "hex": "#FF0000",
    "rgb": "255, 0, 0",
    "hsl": "0, 100, 50",
    "cmyk": "0, 100, 100, 0",
    "ansi16": 91,
    "name": "red",
    "channels": {
      "rgbChannels": 3,
      "cmykChannels": 4,
      "ansiChannels": 1,
      "hexChannels": 1,
      "hslChannels": 3
    }
  }
}

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Field	Type	Example	Description
`hex`	string	`"#FF0000"`	Color in hexadecimal format with hash prefix included
`rgb`	string	`"255, 0, 0"`	Color in red green blue comma-separated format
`hsl`Premium	string	`"0, 100, 50"`	Color in hue saturation lightness comma-separated format
`cmyk`Premium	string	`"0, 100, 100, 0"`	Color in cyan magenta yellow key comma-separated format
`ansi16`Premium	number	`91`	ANSI 16-color code representation of the color
`name`Premium	string	`"red"`	Common English name of the color if available
`channels`	object	`{...}`
`rgbChannels`	number	`3`	Number of RGB color channels always three
`cmykChannels`	number	`4`	Number of CMYK color channels always four
`ansiChannels`	number	`1`	Number of ANSI color channels always one
`hexChannels`	number	`1`	Number of hexadecimal color channels always one
`hslChannels`	number	`3`	Number of HSL color channels always three

Response headers

Every response carries your balance, so your own code always knows where it stands without polling anything. All four are exposed to browsers through CORS.

Header	What it carries
`x-api-remaining-credits`	Credits left in the current cycle
`x-api-credits-used`	Credits spent in the current cycle
`x-api-max-credits`	The allowance for the cycle
`x-api-version`	Version of the endpoint that answered

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change.

Status	Meaning	What to do
`400`	Input was rejected	Read `error`; it names the parameter that has to change.
`401`	Key missing or invalid	Check the header name and the key value.
`403`	Key valid, but not permitted here	A key restriction or an IP allow-list — never a bad key.
`429`	Rate limited, or out of credits	Read `error` to tell them apart, then back off or top up.

What a call costs — 2 credits per call

Credits are shared across every APIVerve API — one balance, one key, one bill. Failed requests never count against it, so a rejected input costs nothing.

Plan	Per month	Credits	Color Converter calls	Per 1,000 calls
Free	Free	200	100	Free
Starter	$29.99	200,000	100,000	$0.30
Pro	$99.99	1,000,000	500,000	$0.20
Mega	$299.99	4,000,000	2,000,000	$0.15

Calls are what the credits buy at this API's rate — spend them here, on any of the other APIs, or across both. Nothing is reserved per endpoint.
