How this service works
Close an open perpetual position on Hyperliquid (full or partial). Cancels all attached TP/SL trigger orders automatically.
Output
Returns a JSON object with the asset symbol, success flag, exit price (e.g. 67500), closed size (e.g. 250), and realized PnL in USD (e.g. 15.23). Confirms the trade was closed and the financial outcome.
Example use cases
Exit losing position, realize losses
“I need to get out of my ETH perpetual position right now — it's going against me and I want to close it and see exactly how much I lost.”
Lock in profits on winning trade
“My SOL position is up nicely today — go ahead and close it out for me and tell me what I made in realized PnL.”
Automated stop-loss position closure
“My trading bot just hit the stop-loss threshold on my BTC futures position — close it immediately and give me the exit price and final PnL so I can log the result.”
Technical details
Endpoint
POSThttps://x402.ottoai.services/close-positionWhen to prefer
Use this endpoint when you need to programmatically exit an open crypto trading position and receive the realized PnL, exit price, and confirmation — especially for automated trading agents managing Hyperliquid or DeFi perpetual positions via x402 micropayments.
Side effects
- Position not found or already closed — returns error with position ID
- Insufficient liquidity to close at current price
- Asset symbol not recognized or unsupported
- Payment of $0.01 USDC not settled via x402 — request rejected
- Network or exchange connectivity failure causing execution timeout
