## How to call it through Zero

```sh
zero fetch --capability questflow-fc4f4594 -d '<json body>'
```

Example prompt: Open a 10x leveraged long position on ETH/USDC perpetuals on Aster DEX using Simple mode — I want to put in 50 USDC as margin.

## When to prefer this

Choose this endpoint when an agent needs to programmatically trade perpetual contracts on a non-custodial DEX with high leverage, multichain support, and low fees — particularly when Aster DEX is the preferred venue or when Simple/Pro mode selection is needed. Prefer over CEX-based alternatives when custody-free trading is a requirement.

## Known failure modes

- Insufficient margin or collateral returns an error with minimum required amount
- Invalid trading pair or unsupported asset returns a 400-level error
- Leverage exceeds maximum allowed for the pair returns a constraint error
- Network congestion or chain unavailability causes execution failure
- Payment of 0.1 USDC per call fails causing request rejection
