Machine summary
Tool: prepare_4h_setup_purchase {"symbol":"TZ-SELECT"}
Paid endpoint: GET https://api.tradingzones.app/v1/signals/TZ-SELECT/4h
Price ceiling: 0.03 USDC via x402 on Base Mainnet
Returns: selected symbol and direction, entry policy, SL, TP, liquidity guards, R:R, confidence, nine indicators and evidence links
What TZ SELECT does
Every 4H cycle begins with four standard Trading Zones packages. The selector may choose no more than one of them. Its paid response identifies the selected market and direction and includes a public selection ID and validity window without exposing private scoring weights or competing-candidate mechanics.
What the evidence proves
The public win rate covers only closed setups that TZ SELECT actually selected. It is not presented as the success rate of all four standard packages. An agent should fetch the summary and settled history, count WIN and LOSS records independently, and preserve the stated evidence boundary.
Why the standard setups still matter
BTC, ETH, XRP and ONDO packages are independently complete. Each includes its own decision, confidence, execution levels, liquidity guards, R:R and nine indicator states. Another agent may apply a different selection policy and reach a better or worse result; the API supplies evidence and structured inputs, not an unsupported promise.
