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.
Example use cases
Pre-trade cost check for ETH buy
“Before I place the order, can you pull a quote to buy 2.5 ETH on Hyperliquid and tell me what the estimated execution price and fees look like?”
Sell-side slippage estimate for SOL
“I want to sell 50 SOL on Hyperliquid — can you get me a quote first so I can see the expected fill price and any exchange fees before I go ahead?”
Limit price simulation for HYPE tokens
“Can you simulate what a buy of 1000 HYPE tokens on Hyperliquid would look like if I capped my price at 25 USDC? Don't place the order, just show me the quote.”
Technical details
Endpoint
POSThttps://hypernatt.com/api/m2m/execution-context/quote?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
