Install the CLI (the skill drives it under the hood); include the [ows] extra # so `peaqos wallet ...` works inside the skill's onboarding flow. pip install 'peaq-os-cli[ows]' # 2. Add the peaqos skill to your agent (auto-detects Claude Code, Cursor, or Windsurf) npx skills add peaqnetwork/peaq-os-skills ``` Then invoke `/peaqos` in any Claude Code session. To target a specific runtime explicitly, add `--agent claude-code | cursor | windsurf`. See the [peaqOS AI page](/peaqos/peaqos-ai) for details and the manual upload path for ChatGPT / custom GPTs. ### Works with The `peaqos` skill ships first-class adapters for Claude Code, Cursor, and Windsurf — auto-detected, or selected with `--agent`. Hosted assistants without a local CLI (ChatGPT, Claude Projects, custom GPTs) can load `AGENT-PROMPT.md` as a system prompt manually. The skill calls the JavaScript and Python SDKs through the CLI. Tabs below apply once you start editing code yourself. ### One command ```bash theme={"theme":{"light":"github-light-default","dark":"github-dark"}} pip install peaq-os-cli # Optional: include OWS wallet commands (peaqos wallet create / import / list / …) pip install 'peaq-os-cli[ows]' peaqos init && peaqos activate --doc-url "https://example.com/docs" --data-api "https://example.com/events" ``` **After running `peaqos init`, open your `.env` and verify every contract address against the [peaq mainnet contracts](#peaq-mainnet-contracts) table on this page.** A known bug in the init wizard can silently write a contract address to the wrong variable name. If any address is missing or wrong, correct it manually before running `peaqos activate`. Drives the same flows as the SDKs from your terminal: `peaqos init`, `peaqos whoami`, `peaqos activate`, `peaqos qualify event`, `peaqos qualify mcr`, `peaqos show machine`, `peaqos show operator machines`, `peaqos wallet`. See [peaqOS CLI](/peaqos/cli) for the full command reference. CLI and SDK wallet helpers live on [Wallets (OWS)](/peaqos/wallets). ### Package ```bash theme={"theme":{"light":"github-light-default","dark":"github-dark"}} npm install @peaqos/peaq-os-sdk viem dotenv ``` OWS wallet helpers (`createWallet`, `importWallet`, `PeaqosClient.fromWallet`, …) work out of the box; `@open-wallet-standard/core` is bundled as a regular dependency of `@peaqos/peaq-os-sdk`. See [Wallets (OWS)](/peaqos/wallets) for the full surface. `dotenv` is optional but recommended: `PeaqosClient.fromEnv()` reads from `process.env`, so `import "dotenv/config"` at the top of your entry file is the simplest way to load `.env`. ### Language + runtime * Node.js ≥ 22 * TypeScript ≥ 5 * Package exports both ESM and CJS builds; no bundler workarounds required. ### Imports ```typescript theme={"theme":{"light":"github-light-default","dark":"github-dark"}} import "dotenv/config"; import { PeaqosClient } from "@peaqos/peaq-os-sdk"; ``` Full method reference on [SDK JS](/peaqos/sdk-reference/sdk-js). Error class hierarchy on [errors](/peaqos/sdk-reference/errors). ### Package ```bash theme={"theme":{"light":"github-light-default","dark":"github-dark"}} python3 -m venv .peaq-os source .peaq-os/bin/activate pip install "peaq-os-sdk>=0.4.0" python-dotenv # Optional: include the OWS wallet helpers (createWallet, importWallet, …) pip install "peaq-os-sdk[ows]>=0.4.0" ``` `python-dotenv` is optional but recommended: `PeaqosClient.from_env()` reads from dotenv, so `load_dotenv()` at the top of your entry file is the simplest way to load .env. ### Language + runtime * Python ≥ 3.10 * `web3.py` pulled in automatically. * Virtualenv strongly recommended. The commands above set one up. ### Imports ```python theme={"theme":{"light":"github-light-default","dark":"github-dark"}} from peaq_os_sdk import PeaqosClient ``` Full method reference on [SDK Python](/peaqos/sdk-reference/sdk-python). Error class hierarchy on [errors](/peaqos/sdk-reference/errors). ### Workspace ```bash theme={"theme":{"light":"github-light-default","dark":"github-dark"}} git clone https://github.com/peaqnetwork/peaq-robotics-ros2.git cd peaq-robotics-ros2 ``` ### Build ```bash theme={"theme":{"light":"github-light-default","dark":"github-dark"}} source /opt/ros/jazzy/setup.bash # Docker image: source /opt/ros/humble/setup.bash # Native host only: python3 -m pip install -r requirements.txt colcon build --packages-select peaq_ros2_interfaces peaq_ros2_peaqos peaq_ros2_examples source install/setup.bash ``` ### Run ```bash theme={"theme":{"light":"github-light-default","dark":"github-dark"}} cp peaq_ros2_examples/config/peaq_robot.example.yaml peaq_ros2_examples/config/peaq_robot.yaml # Edit peaq_ros2_examples/config/peaq_robot.yaml and set peaq_os.enabled: true. ros2 run peaq_ros2_peaqos peaqos_node --ros-args \ -p config.yaml_path:=peaq_ros2_examples/config/peaq_robot.yaml ``` Full method mapping on [ROS 2 SDK reference](/peaqos/sdk-reference/ros2/overview). End-to-end commands on [ROS 2 machine runtime](/peaqos/guides/ros2-machine-runtime). ## Environment variables | Variable | Required | Default | Purpose | | :-------------------------------- | :-------------- | :---------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | `PEAQOS_RPC_URL` | Yes | n/a | peaq chain RPC endpoint | | `PEAQOS_PRIVATE_KEY` | Yes | n/a | Owner wallet private key (hex, `0x...`) | | `PEAQOS_NETWORK` | CLI only | n/a | `mainnet` or `testnet`. Selects address + URL defaults for the CLI's `peaqos init`. SDK clients ignore it. | | `PEAQOS_GAS_STATION_URL` | CLI only | n/a | Faucet base URL. Set to `https://depinstation.peaq.network` for the public peaq-hosted Gas Station. Required for the `peaqos activate` funding step unless `--skip-funding` is set or the wallet already meets the gas threshold. | | `OWS_PASSPHRASE` | No | n/a | OWS vault passphrase used by the SDK and CLI wallet helpers (`createWallet`, `importWallet`, `exportWallet`, …). The SDK raises `PeaqosError` if neither this nor the inline `passphrase` arg is set (no interactive prompt). The CLI reads it when `PEAQOS_OWS_WALLET` is set, prompting interactively if unset. See [Wallets (OWS)](/peaqos/wallets). | | `IDENTITY_REGISTRY_ADDRESS` | Yes | n/a | Identity Registry contract. See [peaq mainnet contracts](#peaq-mainnet-contracts) for the canonical address. | | `IDENTITY_STAKING_ADDRESS` | Yes | n/a | Identity Staking contract | | `EVENT_REGISTRY_ADDRESS` | Yes | n/a | Event Registry contract | | `MACHINE_NFT_ADDRESS` | Yes | n/a | Machine NFT (ONFT) contract | | `DID_REGISTRY_ADDRESS` | Yes | n/a | DID Registry precompile address (`0x...0800` on every peaq runtime) | | `BATCH_PRECOMPILE_ADDRESS` | Yes | n/a | Batch precompile for multi-call bonding (`0x...0805` on every peaq runtime) | | `MACHINE_ACCOUNT_FACTORY_ADDRESS` | No | n/a | `MachineAccountFactory`. Required only for smart-account deploy / predict. | | `MACHINE_NFT_ADAPTER_ADDRESS` | No | n/a | `MachineNFTAdapter` (LayerZero ONFT adapter). Required only for `bridge_nft` / `bridgeNft` when `source="peaq"`. | | `PEAQOS_OWS_WALLET` | CLI only | n/a | Active OWS vault wallet name. When set, the CLI loads the wallet via `OWS_PASSPHRASE` and skips `PEAQOS_PRIVATE_KEY`. Set by `peaqos wallet use` or `peaqos init` (`wallet` path). | | `PEAQOS_MCR_API_URL` | Set for mainnet | `http://127.0.0.1:8000` | MCR API base URL. The default is for self-hosted dev. Set to `https://mcr.peaq.xyz` to read from the public peaq-hosted MCR. | | `PEAQOS_ORCHESTRATION_URL` | Scale only | n/a | Machine Markets orchestrator base URL. The canonical peaq-managed endpoint is `https://orchestration.peaq.xyz`. Read by the SDK (`client.orchestration`) and CLI (`peaqos scale ...`). | | `PEAQOS_API_KEY` | SDK, optional | n/a | Platform API key sent as `x-api-key` on `client.orchestration` requests. Required only when the orchestrator runs with `PEAQOS_REQUIRE_API_AUTH=true`. | | `PEAQOS_ORCH_API_KEY` | CLI, optional | n/a | Same platform API key as `PEAQOS_API_KEY` but under the CLI-specific name. `peaqos init` writes this; `peaqos scale ...` reads it. Set both names to the same value if you use the CLI and SDK in the same env. | | `PEAQOS_TELEMETRY` | No | on | Anonymous SDK usage telemetry toggle. Set to `0` to disable. SDK only (JS + Python); the CLI sends none. See [Telemetry](#telemetry). | | `DO_NOT_TRACK` | No | n/a | Cross-vendor opt-out convention: set to `1` to disable SDK telemetry (same effect as `PEAQOS_TELEMETRY=0`). | Full reference with defaults on [SDK JS environment](/peaqos/sdk-reference/sdk-js) and [SDK Python environment](/peaqos/sdk-reference/sdk-python). ### Telemetry The JavaScript and Python SDKs emit anonymous usage telemetry — which SDK operations run, tagged with a random install ID and with IP collection off (via PostHog, EU-hosted) — to help prioritize the roadmap. No private keys, wallet secrets, or machine data are sent. Telemetry is on by default; disable it with `PEAQOS_TELEMETRY=0` or the cross-vendor `DO_NOT_TRACK=1`. The CLI sends none. ## Public RPC endpoints Use any of the endpoints below for `PEAQOS_RPC_URL`. QuickNode is the primary set; OnFinality and PublicNode are fallbacks. All of them accept EVM JSON-RPC calls. For private dedicated endpoints, see the [QuickNode](https://www.quicknode.com/guides/quicknode-products/how-to-use-the-quicknode-dashboard#create-a-quicknode-endpoint) and [OnFinality](https://documentation.onfinality.io/support/the-enhanced-api-service) guides.

Precompile addresses are identical to mainnet (same fixed slots on every peaq runtime). ### Required | Variable | Address | | :-------------------------- | :------------------------------------------------------------------- | | `IDENTITY_REGISTRY_ADDRESS` | `0x9E9463a65c7B74623b3b6Cdc39F71be7274e5971` | | `IDENTITY_STAKING_ADDRESS` | `0x55f336714aDb0749DbFE33b057a1702405564E3d` | | `EVENT_REGISTRY_ADDRESS` | `0x2DAD8905380993940e340C5cE6d313d5c2780040` | | `MACHINE_NFT_ADDRESS` | `0xB41C2A4f1c19b6B06beaAce0F5CD8439e77C4b1c` | | `DID_REGISTRY_ADDRESS` | `0x0000000000000000000000000000000000000800` (peaq DID precompile) | | `BATCH_PRECOMPILE_ADDRESS` | `0x0000000000000000000000000000000000000805` (peaq batch precompile) | ### Optional | Variable | Address | Needed for | | :-------------------------------- | :------------------------------------------- | :--------------------------------------------------------- | | `MACHINE_ACCOUNT_FACTORY_ADDRESS` | `0x65a4DfEB799dFf8CF15f13816d648a7805d6b1F9` | `deploySmartAccount` / `getSmartAccountAddress` (ERC-4337) | | `ADMIN_FLAGS_ADDRESS` | `0x4181a2Aa34aFb247450FfcBd65be5aBD4Cbee658` | MCR API server (negative-flag + trust-override reads) | **Bridging cannot be exercised on agung.** LayerZero deprecated the agung endpoint (EID `40299`): DVNs and executors are no longer active, so `bridgeNft` / `bridge_nft` cannot relay. No agung `MachineNFTAdapter` appears in peaq deployment records. Leave `MACHINE_NFT_ADAPTER_ADDRESS` unset on agung and test the bridge on peaq mainnet ↔ Base mainnet only. ## Troubleshooting The OTP from your authenticator app was wrong or expired. Generate a fresh code and retry. See full [error code reference](/peaqos/sdk-reference/errors). The faucet throttles owners after repeated bad OTPs. Wait out the lockout window and retry. See [error code reference](/peaqos/sdk-reference/errors). The faucet enforces a per-IP and per-wallet cap. Retry after the cooldown. See [error code reference](/peaqos/sdk-reference/errors). The same owner address has hit the daily funding cap. Wait 24 hours or contact support. See [error code reference](/peaqos/sdk-reference/errors). Set `PEAQOS_RPC_URL` in your environment to a valid peaq chain RPC endpoint (e.g., `https://peaq.api.onfinality.io/public`). Without it, `PeaqosClient.fromEnv()` raises a `ValidationError`. See [Public RPC endpoints](#public-rpc-endpoints) for the full list. Full error taxonomy on [errors](/peaqos/sdk-reference/errors).
