# HyperNatt La Tontine 2.0 — Execution Context Reconciler

## 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-reconciler-01325731 -d '<json body>'
```

Example prompt: I just got a fill on Hyperliquid — can you reconcile it against the baseline quote I saved earlier? Here's the baseline object from my last quote call and here's the fills dataset with the fee included.

## When to prefer this

Use this endpoint when you have already obtained a baseline quote from HyperNatt and need to compare it against actual Hyperliquid order fill data in a post-trade context. Ideal for trading bots, DeFi agents, or La Tontine 2.0 community workflows that need to validate execution quality, detect slippage, or confirm settlement without maintaining server-side session state.

## Known failure modes

- Missing or malformed 'baseline' object causes validation failure
- Fills dataset incomplete or missing required fee fields leads to reconciliation error
- Baseline from a different session or product may produce mismatched result
- Network or payment (x402) failure returns 402 before reconciliation begins
- Unverified account or fill completeness may yield unreliable reconciliation result

## 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 indicating success, a 'product' string identifying the reconciled product, a 'result' object containing reconciliation details (slippage, deviation, match quality, etc.), a 'baseline' echo of the original quote, and a 'delivery' object with additional context about the reconciliation outcome.
