Morse Code API
Morse Code is a simple tool for encoding and decoding Morse code. It returns the encoded or decoded Morse code.
The Morse Code API provides reliable and fast access to morse code data through a simple REST interface. Built for developers who need consistent, high-quality results with minimal setup time.
To use Morse Code, you need an API key. You can get one by creating a free account and visiting your dashboard.
POST Endpoint

Here are examples of how to call the Morse Code API in different programming languages:
curl -X POST \

-H "Content-Type: application/json" \

error | string | null | Contains error message if status is "error", otherwise null | null |
data | object | null | Contains the API response data if successful, otherwise null | {...} |

| Field | Type | Sample Value |
|---|---|---|
text | string | |
morse | string | |
stats | object | |
â”” characters | number | |
â”” dits | number | |

| Header Name | Required | Example Value | Description |
|---|---|---|---|
X-API-Key | required | your_api_key_here | Your APIVerve API key. Found in your dashboard under API Keys. |
Accept | optional | application/json | Specify response format: application/json (default), application/xml, or application/yaml |
User-Agent | optional | MyApp/1.0 | Identifies your application for analytics and debugging purposes |

GraphQL AccessALPHA
Access Morse Code through GraphQL to combine it with other API calls in a single request. Query only the morse code 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 {
morsecode(
input: {
audio: true
text: "This Is A Message"
}
) {
text
morse
stats {
characters
dits
dahs
}
valid
audio {
audioFile
format
downloadURL
duration
frequency
sampleRate
expires
}
}
}Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.
CORS Support
The Morse Code API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call Morse Code 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 Morse Code directly from JavaScript running in the browser without encountering CORS errors. No proxy server or additional configuration needed.
Rate Limiting
Morse Code API requests are subject to rate limiting based on your subscription plan. These limits ensure fair usage and maintain service quality for all Morse Code 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 |
Learn more about rate limiting →
Rate Limit Headers
When rate limits apply, each Morse Code 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, Morse Code 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 Morse Code:
- Monitor the rate limit headers to track your Morse Code usage (Free plan only)
- Cache morse code responses where appropriate to reduce API calls
- Upgrade to Pro or Mega for guaranteed no-throttle Morse Code performance
Note: Morse Code rate limits are separate from credit consumption. You may have credits remaining but still hit rate limits when using Morse Code on Free tier.
Error Codes
The Morse Code 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 |

Frequently Asked Questions
How do I get an API key for Morse Code?
How many credits does Morse Code cost?
Each successful Morse Code API call consumes credits based on plan tier. Check the pricing section above for the exact credit cost. Failed requests and errors don't consume credits, so you only pay for successful morse code lookups.
Can I use Morse Code in production?
The free plan is for testing and development only. For production use of Morse Code, upgrade to a paid plan (Starter, Pro, or Mega) which includes commercial use rights, no attribution requirements, and guaranteed uptime SLAs. All paid plans are production-ready.
Can I use Morse Code from a browser?
What happens if I exceed my Morse Code credit limit?
When you reach your monthly credit limit, Morse Code API requests will return an error until you upgrade your plan or wait for the next billing cycle. You'll receive notifications at 80% and 95% usage to give you time to upgrade if needed.
