Integrate in three simple steps

Clean REST endpoints that return JSON. Works with any language, framework or no-code tool.

1

Pick an endpoint

Choose from image prompts, ASMR & automation prompts, CapCut templates, presets, ringtones and more.

2

Send a request

A simple GET request — filter with query parameters like ?tag=Featured. No SDK required.

3

Render in your app

Parse the JSON and display it. CORS is enabled, so it works from web, mobile and server alike.

// Fetch featured AI image prompts
const res = await fetch(
  "https://app-data.org/api/get_prompts.php?tag=Featured"
);
const prompts = await res.json();

prompts.forEach(p => {
  render(p.imageUrl, p.prompt, p.tags);
});
# Get the ringtones & sounds library
curl -s \
  "https://app-data.org/RSTones/api.php" \
  | jq '.[0]'

# => { "name": "...", "category": "ringtones",
#      "url": "https://app-data.org/RSTones/..." }
// Server-side fetch in PHP
$json = file_get_contents(
  "https://app-data.org/api/get_prompts.php"
);
$prompts = json_decode($json, true);

foreach ($prompts as $p) {
  echo $p['prompt'];
}
