Connectors

Already building with LangGraph or LangChain? Skip the boilerplate — the connectors wrap the Python Agent SDK as a graph node or HITL middleware so your agent pauses on interrupt(), fans the approval out to every registered device, and resumes from a webhook.

LangGraph Connector

langgraph-noxy — drop-in HITL node for any LangGraph state graph.

LangChain Connector

langchain-noxy — HITL middleware for create_agent tool calls.

Prefer to wire decisions yourself? Pick an Agent SDK below and call send_decision directly.

Agent SDKs

Agent SDKs live on your server. They wrap the relay's Agent API with idiomatic types, perform the per-device post-quantum encryption locally, and provide a one-call sendDecisionAndWaitForOutcome helper.

Node.js SDK

@noxy-network/node-sdk — Node 22+, ESM. Server agents and serverless functions.

Python SDK

noxy-sdk on PyPI — Python 3.10+. LangChain, LlamaIndex, custom orchestrators.

Go SDK

github.com/noxy-network/go-sdk — Go 1.21+, CGO for the PQ primitives.

Rust SDK

noxy-sdk on crates.io — Tokio async runtime.

All Agent SDKs share the same surface:

Method	Purpose
`initNoxyAgentClient(config)`	Construct the client. Loads the post-quantum primitives.
`sendDecision(identityId, payload)`	Route an encrypted decision to every device of the identity.
`getDecisionOutcome({decisionId, identityId})`	Single outcome poll.
`waitForDecisionOutcome(options)`	Backoff loop until terminal or timeout.
`sendDecisionAndWaitForOutcome(identityId, payload, options?)`	Convenience — send + wait in one call.
`getQuota()`	Current quota for your application.

Client SDKs

Client SDKs live on user-facing surfaces. They register a device once with the relay using your APP_SIGNING_SECRET, then receive encrypted decisions on an open stream and submit outcomes back.

Browser SDK

@noxy-network/browser-sdk — WebSocket transport, IndexedDB + Web Crypto storage.

iOS SDK

Swift Package — gRPC + Keychain storage. Optional APNs wake-up.

Android SDK

Kotlin / Android 7.0+ — gRPC + EncryptedSharedPreferences. Optional FCM wake-up.

Telegram Bot SDK

@noxy-network/telegram-bot-sdk — Node 18+, pairs with GrammY / Telegraf.

All Client SDKs share the same shape:

Method	Purpose
`createNoxyClient(options)` / `initialize()`	Load or create the device, connect, authenticate.
`on(handler)`	Receive decrypted decisions; handler decides UI.
`submitDecisionOutcome` / `sendDecisionOutcome`	Publish APPROVE or REJECT for a decision id.
`rotateKeys()`	Generate fresh device keys, publish new public keys.
`revokeDevice()`	Remove the device from the relay.
`close()`	Disconnect cleanly.

Example projects

Reference agents live in the official noxy-network/agent-examples repository. Each is a self-contained project with its own README and .env.example — clone it, configure, and run in demo or live mode.

Sale Trigger Agent — Python e-commerce/marketing agent that watches competitor sales via Tavily search. When it spots a price drop worth reacting to, it routes a promotional email through Noxy and only sends to customers after you approve. Built on the LangGraph connector (langgraph-noxy + noxy-sdk).
Liquidation Sentinel Agent — Node.js (TypeScript) 24/7 Aave v3 health-factor watchdog on Ethereum or Base. When your position drifts into danger, it drafts a rescue plan and Noxy asks you to approve before any repay or supply transaction is broadcast. Uses the Node.js SDK (send decision + poll for outcome).
Yield Rebalancer Agent — Node.js (TypeScript) cross-protocol lending yield scanner via DeFiLlama. It compares net APY after gas and friction, then routes a rebalance proposal through Noxy and only moves funds on-chain after you approve. Uses the Node.js SDK (send decision + poll for outcome).

Picking the right pair

If your agent is in…	And your users are on…	Recommended pair
Node.js / TypeScript	Web	Node.js SDK + Browser SDK
Python	iOS / Android	Python SDK + iOS SDK / Android SDK
Go / Rust	Telegram	Go SDK or Rust SDK + Telegram Bot SDK
Anything	Multiple surfaces	Any Agent SDK; install Client SDKs on each surface — outcomes are unified per identity.
