Test Markdown to Image 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

    input: {
      markdown: "# Sample Markdown Document

This is a **sample** markdown document that will be converted to an image.

## Features

CORS Support

The Markdown to Image API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call Markdown to Image 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 Markdown to Image directly from JavaScript running in the browser without encountering CORS errors. No proxy server or additional configuration needed.

Rate Limiting

Markdown to Image API requests are subject to rate limiting based on your subscription plan. These limits ensure fair usage and maintain service quality for all Markdown to Image 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 Markdown to Image 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, Markdown to Image 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 Markdown to Image:

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

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

Error Codes

The Markdown to Image 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
