Reading Time Calculator API
Reading Time Calculator estimates how long it will take to read a given text. It calculates reading time based on word count and customizable reading speed (WPM).
The Reading Time Calculator API provides reliable and fast access to reading time calculator data through a simple REST interface. Built for developers who need consistent, high-quality results with minimal setup time.
To use Reading Time Calculator, you need an API key. You can get one by creating a free account and visiting your dashboard.

GraphQL AccessALPHA
Access Reading Time Calculator through GraphQL to combine it with other API calls in a single request. Query only the reading time calculator 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/graphqlquery {
readingtime(
input: {
text: "This is a sample article with multiple paragraphs. Reading time will be calculated based on word count. The average reading speed is 250 words per minute, which can be customized. This helps content creators provide accurate time estimates to their readers."
wpm: 250
}
) {
text_length
word_count
reading_time_minutes
reading_time_seconds
reading_time_text
words_per_minute
}
}Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.
CORS Support
The Reading Time Calculator API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call Reading Time Calculator directly from browser-based applications without proxy servers.
| CORS Header | Value | Description |
|---|---|---|
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 Reading Time Calculator directly from JavaScript running in the browser without encountering CORS errors. No proxy server or additional configuration needed.
Rate Limiting
Reading Time Calculator API requests are subject to rate limiting based on your subscription plan. These limits ensure fair usage and maintain service quality for all Reading Time Calculator users.
| Plan | Rate Limit | Description |
|---|---|---|
| Free | 5 requests/min | Hard rate limit enforced - exceeding will return 429 errors |
| Starter | No Limit | Production ready - standard traffic priority |
| Pro | No Limit | Production ready - preferred traffic priority |
| Mega | No Limit | Production ready - highest traffic priority |

Rate Limit Headers
When rate limits apply, each Reading Time Calculator response includes headers to help you track your usage:
| Header | Description |
|---|---|
X-RateLimit-Limit | Maximum number of requests allowed per time window |
X-RateLimit-Remaining | Number of requests remaining in the current window |
X-RateLimit-Reset | Unix timestamp when the rate limit window resets |
Handling Rate Limits
Free Plan: When you exceed your rate limit, Reading Time Calculator 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 Reading Time Calculator:
- Monitor the rate limit headers to track your Reading Time Calculator usage (Free plan only)
- Cache reading time calculator responses where appropriate to reduce API calls
- Upgrade to Pro or Mega for guaranteed no-throttle Reading Time Calculator performance
Note: Reading Time Calculator rate limits are separate from credit consumption. You may have credits remaining but still hit rate limits when using Reading Time Calculator on Free tier.
Error Codes
The Reading Time Calculator API uses standard HTTP status codes to indicate success or failure:
| Code | Message | Description | Solution |
|---|---|---|---|
200 | OK | Request successful, data returned | No action needed - request was successful |
400 | Bad Request | Invalid request parameters or malformed request | Check required parameters and ensure values match expected formats |
401 | Unauthorized | Missing or invalid API key | Include x-api-key header with valid API key from dashboard |
403 | Forbidden | API key lacks permission or insufficient credits | Check credit balance in dashboard or upgrade plan |
429 | Too Many Requests | Rate limit exceeded (Free: 5 req/min) | Implement request throttling or upgrade to paid plan |
500 | Internal Server Error | Server error occurred | Retry request after a few seconds, contact support if persists |
503 | Service Unavailable | API temporarily unavailable | Wait and retry, check status page for maintenance updates |
