Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-liquidation-price-calculator-long-position-d32897f1 -d '<json body>'
```

Example prompt: What's the liquidation price for a long position I opened at $100 with 10x leverage and a 0.5% maintenance margin rate?

## When to prefer this

Use this endpoint when you need a fast, pay-per-call, no-signup computation of the liquidation price for a leveraged LONG futures or perpetual position. Prefer this over manual formula implementations when you need verifiable, schema-tagged results delivered via USDC micropayment (x402 on Base or Solana). Not suitable for short positions (use the corresponding short endpoint) or for positions with complex cross-margin calculations.

## Known failure modes

- Missing required fields (mmr, entry, leverage) result in a validation error
- Non-numeric or zero values for entry or leverage may produce undefined/error responses
- Leverage values at or below 1 may yield nonsensical liquidation prices
- Payment failure via x402 protocol returns a 402 response blocking the computation

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object containing the computed liquidation price for the long position (liq_price), along with the echoed input fields (mmr, entry, leverage) and a schema identifier (schema: 'delx/util-liq-price-long/v1').
