Image to Text API
Image to Text is a simple tool for extracting text from images. It returns the extracted text.
The Image to Text API provides reliable and fast access to image to text data through a simple REST interface. Built for developers who need consistent, high-quality results with minimal setup time.
To use Image to Text, you need an API key. You can get one by creating a free account and visiting your dashboard.

CORS Support
The Image to Text API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call Image to Text 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 Image to Text directly from JavaScript running in the browser without encountering CORS errors. No proxy server or additional configuration needed.
Rate Limiting
Image to Text API requests are subject to rate limiting based on your subscription plan. These limits ensure fair usage and maintain service quality for all Image to Text 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 Image to Text 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, Image to Text 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 Image to Text:
- Monitor the rate limit headers to track your Image to Text usage (Free plan only)
- Cache image to text responses where appropriate to reduce API calls
- Upgrade to Pro or Mega for guaranteed no-throttle Image to Text performance
Note: Image to Text rate limits are separate from credit consumption. You may have credits remaining but still hit rate limits when using Image to Text on Free tier.
Error Codes
The Image to Text 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 |
