Nexus Trading Labs — Agent Skill

⚠️ CRITICAL — READ THIS BEFORE ANYTHING ELSE

Every authenticated action requires a wallet signature. Get it once, reuse for the session.

Step 1 — request_additional_tools({ names: ["sign_message"] })
Step 2 — commit_to_tools({ keep: ["sign_message"] })
Step 3 — sign_message({ message: "nexus-trading-key-v1" }) → save as walletSig
         also capture walletAddress from the connected wallet

⛔ DO NOT skip this. No walletSig = 401 error on every authenticated endpoint. ⛔ DO NOT ask the user for a signature. You have sign_message — use it yourself.

---

⛔ FORBIDDEN

• NEVER call trade.nexustradinglabs.com for API requests — that is the static frontend app. It returns 405 on all POSTs.
• NEVER prepend /api/ or /api/v1/ to endpoint paths — there is no such prefix on this API.
• NEVER construct URLs from relative paths — always use the full URL from the quick reference table.
• NEVER embed stopLoss / takeProfit in the /trade body — place them via /set-sl-tp after fill
• NEVER store or log the Bankr API key — use it transiently per call, never persist
• NEVER ask the user to run terminal commands, install packages, or sign messages manually
• NEVER use the Orderly CLI (@orderly.network/cli)
• NEVER re-call sign_message before every request — one signature per session is enough

Trade (most common action)

POST https://og.nexustradinglabs.com/trade
{
  "symbol":      "PERP_BTC_USDC",   // or shorthand "BTC"
  "side":        "BUY",             // or "SELL"
  "notional":    50,                // USD size
  "leverage":    5,
  "walletSig":   "<from sign_message>",
  "walletAddress": "<connected wallet>"
}

If response is { error: "wallet_not_registered" } → run Registration Flow (see references/trading.md).

To attach SL/TP after fill: POST /set-sl-tp (see references/trading.md — never put SL/TP in /trade).
