Overview

To use Morse Code, you need an API key. You can get one by creating a free account and visiting your dashboard.

POST Endpoint

URL
https://api.apiverve.com/v1/morsecode

Example

How to call the Morse Code API in different programming languages.

cURL Request
curl -X POST \
  "https://api.apiverve.com/v1/morsecode" \
  -H "X-API-Key: your_api_key_here" \
  -H "Content-Type: application/json" \
  -d '{
  "audio": true,
  "text": "This Is A Message"
}'
JavaScript (Fetch API)
const response = await fetch('https://api.apiverve.com/v1/morsecode', {
  method: 'POST',
  headers: {
    'X-API-Key': 'your_api_key_here',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({

});

const data = await response.json();
console.log(data);
Python (Requests)

Headers

Only X-API-Key is required. Optional headers include Accept for response format negotiation (JSON, XML, or YAML), User-Agent, and X-Request-ID for request tracing. See all request headers →

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.

Test Morse Code in the GraphQL Explorer to confirm availability and experiment with queries.

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

GraphQL Endpoint
POST https://api.apiverve.com/v1/graphql
GraphQL Query Example
query {
  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 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

Morse Code 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 Morse Code 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 →

SDKs for Morse Code

Official Morse Code packages on npm, PyPI, NuGet, and JitPack — plus a Postman collection and an OpenAPI spec. See the SDK guide →

No-Code Integrations

Morse Code works with Zapier, Make, Pipedream, n8n, and Power Automate using the same API key. See setup guides →

Frequently Asked Questions

How do I get an API key for Morse Code?
Sign up for a free account at dashboard.apiverve.com. Your API key will be automatically generated and available in your dashboard. The same key works for Morse Code and all other APIVerve APIs. The free plan includes 1,000 credits plus a 500 credit bonus.
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?
Yes! The Morse Code API supports CORS with wildcard configuration, so you can call it directly from browser-based JavaScript without needing a proxy server. See the CORS section above for details.
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.
