Version 2.8.0. HyperNatt Terminal: liquidation radar, Hyperliquid execution context and Li.Fi cross-chain swap for AI agents. BTC ETH SOL BNB XRP HYPE ZEC. Before an order: estimate depth, VWAP, spread and fees for its size. Between checks: compare liquidity and costs with the previous baseline. After execution: reconcile supplied fills. Read-only data, no custody or order submission. 6 tools, v2.8.0; call get_agent_manifest first. Radar and each execution-context call cost 0.001 USDC via x402 Base/Solana or eligible credits; manifest and MCP swap quote are free (on-chain swap fees apply). Daily MCP trial: one free call per paid tool and per token per client each UTC day. Four tools x seven tokens = up to 28 independent trials; then 0.001 USDC per call. Read trial_policy_v2 and free_tier_status_v1 on the same MCP connection for current availability. A zero daily_cap is the separate credit pool, not the intro allowance.
