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.
