Overview

This API converts Nepali text between three formats: Roman (English keyboard typing), Unicode Devanagari, and Preeti font encoding. It uses a word-dictionary plus phoneme engine for accurate results — e.g. hamro ghar correctly becomes हाम्रो घर.

Endpoint

JavaScript Example

async function nepaliConvert(action, text) {
  const res = await fetch("https://pradipsubedi1.com.np/api/convert.php", {
    method:  "POST",
    headers: { "Content-Type": "application/json" },
    body:    JSON.stringify({ action, text })
  });
  const data = await res.json();
  return data.success ? data.result : Promise.reject(data.error);
}

nepaliConvert("roman_to_unicode", "hamro ghar")
  .then(result => console.log(result)); // हाम्रो घर

PHP Example

$payload = json_encode(["action" => "roman_to_unicode", "text" => "namaste"]);

curl_setopt_array($ch, [
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => $payload,
    CURLOPT_HTTPHEADER => ["Content-Type: application/json"],
]);
$data = json_decode(curl_exec($ch), true);
echo $data["result"]; // नमस्ते

Response

{ "success": true, "result": "नमस्ते" }

Note: Rate limit is 120 requests/minute per IP. CORS is open for all origins so this works from any website.
