Technical details
Endpoint
POSThttps://x402.ottoai.services/trade-perpetualsWhen to prefer
Use this endpoint when you need to programmatically execute a leveraged perpetual futures trade on Hyperliquid with optional risk management orders (TP/SL) in a single atomic call, paying per-use via USDC micropayment on Base, Polygon, or Solana. Prefer this over manual Hyperliquid interaction when automating trading strategies or building agent-driven DeFi workflows.
Side effects
- Insufficient margin or collateral in Otto AI Safe account — returns error indicating underfunded account
- Invalid asset symbol or unsupported perpetual market — returns error or empty response
- Hyperliquid API downtime or connectivity issue — returns upstream service error
- x402 payment failure due to insufficient USDC balance — returns 402 payment required error
- Invalid side parameter (not long or short) — returns validation error
- Stop-loss price above entry for long or below entry for short — may return order rejection
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| side | string | Position direction |
| size | number | Notional size in USDC (NOT margin). For '$10 margin at 25x', use size=250. Required — an omitted size is rejected, never defaulted. |
| asset | string | Asset ticker (BTC, ETH, SOL, etc.). HIP-3 stock perps also accept 'xyz:TSLA' form. |
| leverage | number | Leverage multiplier (1-40 depending on asset) |
| stopLoss | object | Optional stop-loss trigger. Provide EITHER percentage OR price, not both. |
| orderType | string | Default: market. |
| limitPrice | number | Required when orderType is 'limit'. |
| marginMode | string | Default: cross. Stock perps (xyz DEX) are always isolated. |
| takeProfit | object | Optional take-profit trigger. Provide EITHER percentage OR price, not both. |
| userAddress | string | Optional for external x402 callers — the operated account is your verified payment payer, not this field. Internal/dApp callers must send a valid EVM address. |
| stopLossPrice | number | Alias for stopLoss.price. Send exactly one of the two — supplying stopLoss and stopLossPrice together is rejected, including when their values are equal. |
| takeProfitPrice | number | Alias for takeProfit.price. Send exactly one of the two — supplying takeProfit and takeProfitPrice together is rejected, including when their values are equal. |
