SDK Reference

The mini-program SDK is a ~2 KB JavaScript library that gets injected into every mini-program iframe. It provides the window.ais namespace with methods to interact with the AI Supreme Council platform through a secure postMessage bridge.

How the SDK Works​

The SDK is injected as a <script> tag before your app's HTML in the iframe's srcdoc. You do not need to include it yourself -- it is always available as window.ais when your code runs.

Every method call (except platform.* properties) sends a message to the host page and returns a Promise. The host validates permissions, executes the request, and sends the result back.

Your app code                SDK                    Host platform
     |                        |                          |
     |-- ais.chat.send("hi")-->|                          |
     |                        |-- postMessage({           |
     |                        |     method: "chat.send",  |
     |                        |     args: {text: "hi"}    |
     |                        |   }) ---------------------->|
     |                        |                          |-- check permissions
     |                        |                          |-- execute AIS.Chat.send()
     |                        |<-- postMessage({result}) --|
     |<-- Promise resolves ---|                          |
info

All SDK methods are available synchronously as function references, but they return Promises that resolve asynchronously. Always use await or .then() to get results.

TypeScript Support​

TypeScript type definitions are available in sdk/ais.d.ts. Add a reference to your project:

/// <reference path="./ais.d.ts" />

ais.ready(async () => {
  const history = await ais.chat.getHistory(10);
  // history is typed as ais.ChatMessage[]
});

Or copy the AisManifest and AisPermission types for manifest validation in your build tooling.

Lifecycle​

ais.ready(callback)​

Register a callback that fires when the platform bridge is connected and ready. This is the entry point for your app -- wrap all initialization logic inside this callback.

ParameterTypeDescription
callback() => voidFunction to call when the bridge is ready
ais.ready(async function() {
  // Platform is connected, SDK calls will work now
  const user = await ais.auth.getUser();
  document.getElementById('greeting').textContent = 'Hello, ' + user.name;
});
precaución

Do not call other ais.* methods before ais.ready() fires. The postMessage bridge may not be established yet, and calls will hang indefinitely.

ais.onShow(callback)​

Register a callback that fires each time the mini-program becomes visible (e.g., user switches back to the app tab).

ParameterTypeDescription
callback() => voidFunction to call on show
ais.onShow(function() {
  // Refresh data when user returns to the app
  refreshDashboard();
});

ais.onHide(callback)​

Register a callback that fires when the mini-program is hidden (e.g., user switches to chat or another app).

ParameterTypeDescription
callback() => voidFunction to call on hide
ais.onHide(function() {
  // Pause expensive operations
  stopPolling();
});

ais.close()​

Close the mini-program and return to the chat view. The iframe is destroyed after this call.

Returns: Promise<boolean>

document.getElementById('done-btn').addEventListener('click', function() {
  ais.close();
});

Storage​

Per-app isolated key-value storage backed by IndexedDB. Keys are automatically namespaced with mp:{app-name}: so apps cannot access each other's data.

Permission: Always allowed -- no permission required.

ais.storage.get(key)​

Retrieve a value by key. Returns undefined if the key does not exist.

ParameterTypeDescription
keystringThe storage key

Returns: Promise<unknown> -- the stored value, or undefined

const count = await ais.storage.get('visit-count');
console.log('Visits:', count); // number, string, object, array, or undefined

ais.storage.set(key, value)​

Store a key-value pair. The value can be any JSON-serializable type (string, number, boolean, object, array, null).

ParameterTypeDescription
keystringThe storage key
valueunknownThe value to store (must be JSON-serializable)

Returns: Promise<boolean> -- true on success

await ais.storage.set('visit-count', 42);
await ais.storage.set('preferences', { theme: 'dark', fontSize: 16 });

ais.storage.remove(key)​

Delete a key from storage.

ParameterTypeDescription
keystringThe key to remove

Returns: Promise<boolean> -- true on success

await ais.storage.remove('temporary-data');

ais.storage.keys()​

List all keys stored by this mini-program (without the internal mp:{name}: prefix).

Returns: Promise<string[]>

const keys = await ais.storage.keys();
console.log('Stored keys:', keys); // ['visit-count', 'preferences']

Chat​

Read chat history, send messages, and subscribe to new messages in the active conversation.

Permissions required: chat:read for reading, chat:write for sending.

ais.chat.getHistory(limit?)​

Get recent messages from the active chat session.

ParameterTypeDefaultDescription
limitnumber50Maximum number of messages to return

Returns: Promise<ChatMessage[]>

interface ChatMessage {
  role: 'user' | 'assistant' | 'system';
  content: string;
  timestamp?: number;
}
const messages = await ais.chat.getHistory(20);
messages.forEach(function(msg) {
  console.log(msg.role + ': ' + msg.content);
});

ais.chat.send(text)​

Send a message as the user. This triggers the active AI model to generate a response.

ParameterTypeDescription
textstringThe message text to send

Returns: Promise<boolean> -- true on success

await ais.chat.send('Summarize the last 5 messages');
aviso

Calling ais.chat.send() triggers an actual API call to the user's configured AI provider. This consumes tokens and may incur costs. Use responsibly and always inform the user before sending messages programmatically.

ais.chat.onMessage(callback)​

Subscribe to new chat messages. The callback fires for every new message (both user and assistant).

ParameterTypeDescription
callback(msg: ChatMessage) => voidHandler for incoming messages
ais.chat.onMessage(function(msg) {
  if (msg.role === 'assistant') {
    // AI model responded
    updateResponseDisplay(msg.content);
  }
});

Permission required: config:read

ais.config.get()​

Get the full bot configuration object.

Returns: Promise<BotConfig>

interface BotConfig {
  n?: string;   // Bot name
  p?: string;   // Provider ID (e.g., 'anthropic', 'openai', 'gemini')
  m?: string;   // Model ID (e.g., 'claude-sonnet-4-20250514')
  s?: string;   // System prompt
  t?: number;   // Temperature (0.0 - 2.0)
  x?: number;   // Max output tokens

}
const config = await ais.config.get();
console.log('Using model:', config.m);
console.log('System prompt:', config.s);

ais.config.getProvider()​

Get the active provider ID.

Returns: Promise<string> -- e.g., 'anthropic', 'openai', 'gemini', 'xai', 'openrouter', 'ollama'

const provider = await ais.config.getProvider();
if (provider === 'ollama') {
  showLocalModelBanner();
}

ais.config.getModel()​

Permission required: pages:publish

ais.pages.getInfo()​

Get info about the user's published page.

Returns: Promise<PageInfo>

interface PageInfo {
  slug: string | null;
  url: string | null;
  title: string | null;
  updatedAt: number | null;
  hasPage: boolean;
}

ais.pages.claim(slug)​

opts{ title?: string; description?: string }Optional metadata

Returns: Promise<PublishResult>

ais.pages.unpublish()​

Unpublish and release the slug.

Platform Info​

Read-only properties with platform metadata. These are synchronous -- no Promise, no permission required.

ais.platform.version​

The platform version string (semver).

Type: string -- currently '1.0.0'

ais.platform.abi​

The ABI version number. Used to verify compatibility between the SDK and the host platform.

Type: number -- currently 1

if (ais.platform.abi !== 1) {
  ais.ui.toast('This app requires ABI version 1');
  ais.close();
}

Error Handling​

All SDK calls that require permissions will reject with a PermissionDenied error if the app does not have the required permission:

try {
  const history = await ais.chat.getHistory();
} catch (err) {
  if (err.message.includes('PermissionDenied')) {
    console.log('App does not have chat:read permission');
  }
}

Unknown methods return an error with the message Unknown method: {method}.

If the host platform encounters an unexpected error, the Promise rejects with the error message string.

tip

Always wrap SDK calls in try/catch blocks, especially for permission-gated APIs. This makes your app resilient even if the user's platform version differs from what you tested against.
