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/graphql

query {
  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 accepts cross-origin requests from any origin, so it can be called directly from browser-based applications without a proxy. See CORS support →

Rate Limiting

Reading Time Calculator requests are throttled per minute on the Free plan and unthrottled on paid plans. Exceeding the limit returns 429 Too Many Requests; rate-limit usage is reported in the X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset response headers. See per-plan limits and best practices →

Error Codes

The Reading Time Calculator API uses standard HTTP status codes — 200 on success, 400 for invalid parameters, 401 for missing or invalid keys, 403 for insufficient credits, 429 for rate-limit exhaustion, and 500/503 for server-side issues. Each error response includes an X-Request-ID header you can quote when contacting support. See full error handling guide →
