Overview

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.

Endpoint

One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.

GEThttps://api.apiverve.com/v1/colorconverter
curl "https://api.apiverve.com/v1/colorconverter?hex=FF0000" \
  -H "x-api-key: your_api_key_here"
const res = await fetch('https://api.apiverve.com/v1/colorconverter?hex=FF0000', {
  headers: { 'x-api-key': 'your_api_key_here' },
});

if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);

const { data } = await res.json();
console.log(data);
import requests

res = requests.get(
    "https://api.apiverve.com/v1/colorconverter?hex=FF0000",
    headers={"x-api-key": "your_api_key_here"},
    timeout=15,
)
res.raise_for_status()

print(res.json()["data"])
package main

import (
	"fmt"
	"io"
	"net/http"
)

func main() {
	req, _ := http.NewRequest("GET", "https://api.apiverve.com/v1/colorconverter?hex=FF0000", nil)
	req.Header.Set("x-api-key", "your_api_key_here")

	res, err := http.DefaultClient.Do(req)
	if err != nil {
		panic(err)
	}
	defer res.Body.Close()

	out, _ := io.ReadAll(res.Body)
	fmt.Println(string(out))
}

Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.

Authentication

Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.

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.

Parameters

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them.

ParameterTypeDescription
hexRequiredstringThe color in hexadecimal format (e.g., FF0000). Make sure you ommit the #

Response

Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.

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.

FieldTypeExampleDescription
hexPremiumstring"#FF0000"Color in hexadecimal format with hash prefix included
rgbstring"255, 0, 0"Color in red green blue comma-separated format
hslPremiumstring"0, 100, 50"Color in hue saturation lightness comma-separated format
cmykPremiumstring"0, 100, 100, 0"Color in cyan magenta yellow key comma-separated format
ansi16Premiumnumber91ANSI 16-color code representation of the color
namePremiumstring"red"Common English name of the color if available
channelsobject{...}
rgbChannelsnumber3Number of RGB color channels always three
cmykChannelsnumber4Number of CMYK color channels always four
ansiChannelsnumber1Number of ANSI color channels always one
hexChannelsnumber1Number of hexadecimal color channels always one
hslChannelsnumber3Number of HSL color channels always three

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.

StatusMeaningWhat to do
400Input was rejectedRead error; it names the parameter.
401Key missing or invalidCheck the header name and the key value.
403Key valid, but not permittedA key restriction or IP allow-list; see key scoping.
429Rate limited, or out of creditsRead error to tell them apart; see rate limits.
