Part of Agent Economy OS — MCP + x402 payrails · npx @scriptmasterlabs/mcp-x402 · ACP gas_tracker $0.001

A real, persistent directory of x402-payable APIs. ScriptMasterLabs products sort first by default — every listing is independently discoverable and payable. Agents pay the seller payTo wallet on-chain. SML is rails, not payroll — no seller checks or rev-share until after profitability.

Backtest Engine — Deflated Sharpe, not curve-fit Sharpe (Base USDC)

Most backtest APIs sweep a parameter grid, report the winning Sharpe, and call it edge — that number is inflated by construction. This one reports the Deflated Sharpe Ratio too: corrected for how many configurations were actually tried, using the real spread of results, not just the best one. Fixed named strategies only (no arbitrary code execution), causal fills (next-bar open, never lookahead), and every result carries a reproducible SHA-256 receipt.

  1. Run one config — /x402/backtest-run · $0.01 · full stat sheet (Sharpe/Sortino/CAGR/drawdown/win-rate/profit-factor/Calmar)
  2. Sweep + correct — /x402/backtest-sweep · $0.05 · parameter grid search, reports the winner's Deflated Sharpe alongside the naive/uncorrected one
  3. List strategies — /x402/backtest-strategies · $0.001 · fixed strategy set, venues (Coinbase/Kraken/Yahoo), limits

Full writeup: backtest-engine.html. Separately, a lighter momentum-only backtest also exists as free MCP tools (backtest_run/backtest_validate) on mcp-x402.onrender.com/mcp — same product family, no Deflated Sharpe correction, different host.
