• GET /api/x402/ml/signals/1 — Latest machine-learning price predictions for one crypto pair, one row per forecast horizon (XGBoost models retrained and run daily). Returns bullish/bearish probability percentages, the directional signal, magnitude breakdown (pump / grind up / grind down / dump probabilities) with its signal, the candle close the prediction was made from, and the target date. USD and USDT quote variants resolve to the same dataset. A 404 (never charged) means the pair is not tracked by the ML pipeline. (0.1 USDC on Base)
• GET /api/x402/indicators/1 — Get the full set of computed technical indicator signals for a crypto pair as of a market-close date: Ichimoku (TK cross, Kumo breakout, Senkou span cross, edge-to-edge), EMA/SMA price crosses, golden cross, RSI overbought/oversold, ADX trend strength, MACD crosses, and Bollinger Band squeeze. USD and USDT quote variants resolve to the same dataset. (0.05 USDC on Base)
• GET /api/x402/daily-snapshot/1 — Get a daily market snapshot for a crypto pair: Bollinger Bands (upper/middle/lower), key simple moving averages (SMA20/50/200), Ichimoku components (tenkan, kijun, senkou spans), 2-year moving-average multiples, and the weekly 20-week MA. USD and USDT quote variants resolve to the same dataset. (0.05 USDC on Base)
• POST /api/x402/backtest/run-perpetual — Run a USD-margined perpetual-futures backtest (1x, LONG_ONLY or SHORT_ONLY) on historical OHLCV data for a crypto pair, driven by a single technical indicator signal — ideal for algorithmic trading agents. Capital, margin, and P&L are denominated in USD. USD and USDT quote variants resolve to the same dataset. Returns trade-by-trade results, equity curve, and performance metrics (total return, win rate, max drawdown, Sharpe ratio) in USD terms. (0.15 USDC on Base)
• POST /api/x402/assistant/query — Natural-language access to the whole analytics engine: describe what you want in plain English ('Backtest DCAing $100 a week into SOL vs lump sum since 2023', 'How would a 25% short hedge on my 2 BTC have held up last year?') and an LLM compiles it into a validated simulation config, runs it, and narrates the results. Supports all platform capabilities: indicator backtests, DCA simulations (cadence or indicator-triggered), multi-asset portfolio backtests, one-time hedge simulations, and ML signals. The response includes the structured interpretation, the exact config that ran, the full engine result, and a plain-English narration. Stateless: for multi-turn conversations, pass prior turns in `messages` (OpenAI-style [{role, content}]); nothing is stored server-side. (0.5 USDC on Base)
• POST /api/x402/dca/simulate — Simulate a dollar-cost-averaging (DCA) strategy on historical OHLCV data for a crypto pair. Two schedule modes: 'cadence' buys a fixed USD amount daily/weekly/monthly; 'indicator' buys only when a technical indicator signal flips true (e.g. accumulate only while RSI is oversold). Returns every simulated buy, an equity curve (invested vs position value over time), and a summary with total invested, average cost basis, final value, total return and max drawdown. Optional compareTo runs a lump-sum baseline or the same schedule on a second symbol (e.g. DCA into SOL vs BTC). USD and USDT quote variants resolve to the same dataset. (0.05 USDC on Base)
• POST /api/x402/backtest/run-inverse — Run a BitMEX-style inverse perpetual backtest: margin, capital, and P&L are denominated in the underlying coin (BTC or ETH) — no USD involved. Both LONG_ONLY and SHORT_ONLY directions are supported, driven by a single technical indicator signal — ideal for algorithmic trading agents. Only BTC and ETH pairs (USDT quote variants are normalized automatically). initialCapital is in coin units (default 1). Returns trades, equity curve, and performance metrics in coin terms. (0.2 USDC on Base)
• POST /api/x402/indicators/history — Query historical OHLCV-based time series for up to 5 technical indicator signals on a crypto pair: pick a timeframe (D, W, 3D, 1h, 4h or 12h), a date range, and 1-5 indicators (backtest signal names like rsi14 expand to both direction columns; raw columns like rsi14_overbought also accepted). Returns time + close rows with one column per indicator. Flat $0.10 per query regardless of indicator count. USD and USDT quote variants resolve to the same dataset. (0.1 USDC on Base)
• POST /api/x402/portfolio/backtest — Backtest a multi-asset crypto portfolio over daily OHLCV data: provide fixed-weight allocations (e.g. 60% BTC / 40% ETH), an optional monthly or quarterly rebalancing rule, and a date range. Returns the portfolio equity curve, per-asset performance (start/end value, return), and risk metrics computed from daily returns (total return, CAGR, Sharpe and Sortino ratios, max drawdown, annualized volatility). Assets with shorter history start the portfolio at the first common trading date. USD and USDT quote variants resolve per asset. (0.25 USDC on Base)
• POST /api/x402/portfolio/hedge-simulation — Simulate a one-time portfolio hedge: given spot holdings (e.g. 2 BTC), open a short perpetual position sized as a fraction of the spot value (hedgeRatio 0-1, 1x) at the start date, and manage it with an exit rule — hold to the end, a trailing stop, fixed take-profit/stop-loss, or an indicator signal flip. Returns the daily equity curve (spot value, hedge P&L, combined vs unhedged portfolio), the hedge entry/exit details, and a summary comparing hedged vs unhedged total return and max drawdown (including drawdown reduction). Commissions are applied per side. The spot leg can optionally be sold on a given date. One-time hedges only — repeated/cadence hedging is not yet supported. (0.25 USDC on Base)
