## 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 hypernatt-la-tontine-2-0-execution-context-quote-64756b42 -d '<json body>'
```

Example prompt: Can you get me a buy-side quote for 0.1 BTC on Hyperliquid right now, with no limit price — just show me what the execution context looks like before I commit?

## When to prefer this

Use this endpoint when you need a pre-trade execution quote on Hyperliquid for one of the supported tokens (BTC, ETH, SOL, BNB, XRP, HYPE, ZEC) without placing a real order. Prefer it over generic swap quote APIs when the user is specifically trading on Hyperliquid and needs fee-inclusive execution context. Ideal for agents performing pre-flight checks before committing capital or validating slippage tolerance.

## Known failure modes

- Invalid symbol not in supported enum (BTC/ETH/SOL/BNB/XRP/HYPE/ZEC) returns error
- quantity_base not matching native szDecimals causes rejection
- Missing required fields (side, symbol, quantity_base) returns validation error
- Caller-supplied observation values treated historically — stale data may affect quote accuracy
- Network issues with Hyperliquid L2 book fetch cause timeouts

## How this service works

HyperNatt Terminal — 6 MCP tools for AI agents: liquidation radar, Hyperliquid execution quotes, context comparison, fill reconciliation and LI.FI cross-chain swaps. Free manifest and daily tool/token trials; paid data calls 0.001 USDC via x402.

## Output

Returns a JSON object with an 'ok' boolean, a 'product' string identifying the asset pair, a 'result' object containing the computed quote details (price, fees, fill estimates), a 'baseline' object with reference pricing context, and a 'delivery' object with execution metadata — all computed without submitting any real order.
