Overview
@ixo/oracles-client-sdk is the official React client for a QiForge oracle. It wraps:
- The streaming chat endpoint over SSE.
- The WebSocket event channel (tool calls, render components, browser tools, AG-UI actions).
- UCAN auth — signing invocations (authentication) and delegations (downstream authorization).
- Browser-side tools and AG-UI actions (so the agent can act on the user’s tab / UI).
Install
react >= 18 and zod ^3 are peer dependencies.
OraclesProvider (required wrapper)
Every hook callsuseOraclesContext(), which throws useOraclesContext must be used within a OraclesProvider if there’s no provider above it. Wrap your app once. The provider holds the wallet, signs transactions, and turns your createDelegation / createInvocation callbacks into the cached auth artifacts the hooks attach to requests.
The connected user’s wallet + Matrix session. Required.
Signs and broadcasts chain transactions (e.g. paying to contract the oracle).
Mints a user→oracle UCAN delegation. The provider caches it and sends it as
x-ucan-delegation.Optional (migration-safe). Mints a short-lived UCAN invocation; the provider sends it as
Authorization: Bearer … + X-Auth-Type: ucan (primary auth). Omit to stay on delegation-only auth.useChat
The primary hook. Provides the message thread, the send function, and live streaming state.IChatOptions):
The oracle’s DID. The SDK resolves its API/WS URL from the oracle’s on-chain config.
The chat session to read/write. Create one with
useOracleSessions().createSession().Called when the oracle returns a payment-required error. Surface a paywall.
Browser-side tools the agent may call on the user’s tab (see below).
Map of render-component name → React component for
render_component events.Override the resolved API / WebSocket URLs (local dev, self-host).
How streamed tokens are flushed to state.
| Field | Type | Notes |
|---|---|---|
messages | IMessage[] | Thread history, including in-flight streamed content. |
sendMessage | (message: string) => void | Submit a user message. |
abortStream | () => Promise<void> | Abort the in-flight response. |
status | 'submitted' | 'streaming' | 'ready' | 'error' | Current chat state. |
isSending | boolean | true while submitting or streaming. |
isLoading | boolean | Initial history fetch in flight. |
error / sendMessageError | Error | undefined | Load error / send error. |
refetchMessages | () => Promise<…> | Re-pull the thread from the server. |
isRealTimeConnected | boolean | WebSocket connection status. |
isConfigReady | boolean | The oracle’s config has resolved. |
isStreaming or events field — use status / isSending for streaming state.
Browser tools
Browser tools let the agent call DOM/UI actions on the user’s tab. Pass them as thebrowserTools option to useChat — a map keyed by tool name. The SDK advertises them to the agent, forwards each call to your fn, and returns the result over the WebSocket.
registerBrowserTools export — browser tools are the browserTools option above.
AG-UI actions
useAgAction registers an agent-invokable action with an optional render. The provider tracks registered actions; useChat advertises them and renders their output inline.
Events
Streamed and WebSocket events are surfaced as the typedAnyEvent union and rendered through renderMessageContent / your uiComponents map. The event eventName values match the wire names:
eventName | What it carries |
|---|---|
tool_call | A tool invocation (and its result). |
render_component | A structured UI component the agent wants displayed. |
browser_tool_call | A call to one of your browserTools. |
Other exports
| Export | Purpose |
|---|---|
useOracleSessions(oracleDid) | Create, list, and delete chat sessions. |
useOraclesConfig(oracleDid) | The oracle’s resolved public config (API URL, model, price). |
useContractOracle() | Pay to contract (subscribe to) an oracle. |
useMemoryEngine() | Read/write the optional persistent memory engine. |
useGetOpenIdToken() / getOpenIdToken() | Mint a Matrix OpenID token for the user. |
renderMessageContent(content) | Turn stored message content into React nodes. |
OraclesProvider, useOraclesContext | The provider + its context accessor. |
@ixo/oracles-client-sdk/live-agent → useLiveAgent | Encrypted voice/video live-agent calls (separate entry point). |
Auth lifecycle
The provider owns auth. From yourcreateDelegation / createInvocation callbacks it:
- Caches the signed delegation and invocation per
(userDid, oracleDid). - Attaches
Authorization: Bearer <invocation>+X-Auth-Type: ucan(primary) andx-ucan-delegation(downstream / fallback) to every request. - Passes the same artifacts on the WebSocket handshake (
auth.invocation/auth.ucanDelegation).
createDelegation again to mint a fresh one (the client-sdk POSTs it to /delegation).
