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

The Color Converter API provides reliable and fast access to color converter data through a simple REST interface. Built for developers who need consistent, high-quality results with minimal setup time.

To use Color Converter, you need an API key. You can get one by creating a free account and visiting your dashboard.

GraphQL AccessALPHA

Access Color Converter through GraphQL to combine it with other API calls in a single request. Query only the color converter data you need with precise field selection, and orchestrate complex data fetching workflows.

Test Color Converter in the GraphQL Explorer to confirm availability and experiment with queries.

Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.

GraphQL Endpoint
POST https://api.apiverve.com/v1/graphql
GraphQL Query Example
query {
  colorconverter(
    input: {
      hex: "FF0000"
    }
  ) {
    hex
    rgb
    hsl
    cmyk
    ansi16
    name
    channels {
      rgbChannels
      cmykChannels
      ansiChannels
      hexChannels
      hslChannels
    }
  }
}

Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.

CORS Support

The Color Converter API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call Color Converter directly from browser-based applications without proxy servers.

CORS HeaderValueDescription
Access-Control-Allow-Origin*Accepts requests from any origin
Access-Control-Allow-Methods*Accepts any HTTP method
Access-Control-Allow-Headers*Accepts any request headers

Browser Usage: You can call Color Converter directly from JavaScript running in the browser without encountering CORS errors. No proxy server or additional configuration needed.

Rate Limiting

Color Converter API requests are subject to rate limiting based on your subscription plan. These limits ensure fair usage and maintain service quality for all Color Converter users.

PlanRate LimitDescription
Free5 requests/minHard rate limit enforced - exceeding will return 429 errors
StarterNo LimitProduction ready - standard traffic priority
ProNo LimitProduction ready - preferred traffic priority
MegaNo LimitProduction ready - highest traffic priority

Learn more about rate limiting →

Rate Limit Headers

When rate limits apply, each Color Converter response includes headers to help you track your usage:

HeaderDescription
X-RateLimit-LimitMaximum number of requests allowed per time window
X-RateLimit-RemainingNumber of requests remaining in the current window
X-RateLimit-ResetUnix timestamp when the rate limit window resets

Handling Rate Limits

Free Plan: When you exceed your rate limit, Color Converter returns a 429 Too Many Requests status code. Your application should implement appropriate backoff logic to handle this gracefully.

Paid Plans: No rate limiting or throttling applied. All paid plans (Starter, Pro, Mega) are production-ready.

Best Practices for Color Converter:

  • Monitor the rate limit headers to track your Color Converter usage (Free plan only)
  • Cache color converter responses where appropriate to reduce API calls
  • Upgrade to Pro or Mega for guaranteed no-throttle Color Converter performance

Note: Color Converter rate limits are separate from credit consumption. You may have credits remaining but still hit rate limits when using Color Converter on Free tier.

Error Codes

The Color Converter API uses standard HTTP status codes to indicate success or failure:

CodeMessageDescriptionSolution
200OKRequest successful, data returnedNo action needed - request was successful
400Bad RequestInvalid request parameters or malformed requestCheck required parameters and ensure values match expected formats
401UnauthorizedMissing or invalid API keyInclude x-api-key header with valid API key from dashboard
403ForbiddenAPI key lacks permission or insufficient creditsCheck credit balance in dashboard or upgrade plan
429Too Many RequestsRate limit exceeded (Free: 5 req/min)Implement request throttling or upgrade to paid plan
500Internal Server ErrorServer error occurredRetry request after a few seconds, contact support if persists
503Service UnavailableAPI temporarily unavailableWait and retry, check status page for maintenance updates
