Authentication

The Cron Expression Generator API requires authentication via API key. Include your API key in the request header:

X-API-Key: your_api_key_here

GraphQL AccessALPHA

Access Cron Expression Generator through GraphQL to combine it with other API calls in a single request. Query only the cron expression generator data you need with precise field selection, and orchestrate complex data fetching workflows.

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

POST https://api.apiverve.com/v1/graphql

query {
  crongenerator(
    input: {
      schedule: "every weekday at 9am"
    }
  ) {
    schedule
    expression
    description
  }
}

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

CORS Support

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

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

Rate Limiting

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

Learn more about rate limiting →

Rate Limit Headers

When rate limits apply, each Cron Expression Generator response includes headers to help you track your usage:

Handling Rate Limits

Free Plan: When you exceed your rate limit, Cron Expression Generator 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 Cron Expression Generator:

• Monitor the rate limit headers to track your Cron Expression Generator usage (Free plan only)
• Cache cron expression generator responses where appropriate to reduce API calls
• Upgrade to Pro or Mega for guaranteed no-throttle Cron Expression Generator performance

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

Error Codes

The Cron Expression Generator API uses standard HTTP status codes to indicate success or failure:
