Overview
Morse Code works by analyzing the data provided and encoding or decoding the Morse code. It uses various sources to determine the data and returns the encoded or decoded Morse code.
Endpoint
One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.
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"
}'const res = 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({
"audio": true,
"text": "This Is A Message"
}),
});
if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);
const { data } = await res.json();
console.log(data);import requests
res = requests.post(
"https://api.apiverve.com/v1/morsecode",
headers={"x-api-key": "your_api_key_here"},
json={
"audio": True,
"text": "This Is A Message"
},
timeout=15,
)
res.raise_for_status()
print(res.json()["data"])package main
import (
"fmt"
"io"
"net/http"
"strings"
)
func main() {
body := strings.NewReader(`{
"audio": true,
"text": "This Is A Message"
}`)
req, _ := http.NewRequest("POST", "https://api.apiverve.com/v1/morsecode", body)
req.Header.Set("Content-Type", "application/json")
req.Header.Set("x-api-key", "your_api_key_here")
res, err := http.DefaultClient.Do(req)
if err != nil {
panic(err)
}
defer res.Body.Close()
out, _ := io.ReadAll(res.Body)
fmt.Println(string(out))
}Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.
Authentication
Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.
A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.
Parameters
Sent as JSON in the request body. Premium parameters are accepted on every plan but only take effect on plans that include them.
| Parameter | Type | Description |
|---|---|---|
textRequired | string | The text to encode or decode in Morse code |
audioOptionalPremium | boolean | Set to true to include an audio file of the Morse code |
Response
Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.

}Response fields
Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.
| Field | Type | Example | Description |
|---|---|---|---|
text | string | "This Is A Message" | Decoded text from the Morse code input |
morse | string | "- .... .. ... / .. ... / .- / -- . ... ... .- --. . " | Original Morse code that was decoded |
stats | object | {...} | Statistics about the Morse code decoding |
characters | number | 17 | Total number of characters in decoded text |
dits | number | 25 | Total count of dits (dots) in Morse code |
dahs | number | 7 | Total count of dahs (dashes) in Morse code |
valid | boolean | true | Whether the Morse code is valid and properly formatted |
audioPremium | object | {...} | Audio file information including URL and metadata |
audioFilePremium | string | "a11f9d7f-1fd2-4b10-86de-82defaf18c57.wav" | Unique identifier for the generated audio file |

Errors
Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.
| Status | Meaning | What to do |
|---|---|---|
400 | Input was rejected | Read error; it names the parameter. |
401 | Key missing or invalid | Check the header name and the key value. |
403 | Key valid, but not permitted | A key restriction or IP allow-list; see key scoping. |
429 | Rate limited, or out of credits | Read error to tell them apart; see rate limits. |
Other ways to use Morse Code
Set up Morse Code on APIVerve, or reach the same source a different way. Your APIVerve account and credits work on all of them — one key, one balance.
