# TASignal Risk Analytics > TASignal Risk Analytics is a paid API for AI agents from tasignal.agentgate.workers.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-28). Returns historical VaR/CVaR, max drawdown, Sharpe/Sortino ratios, realized volatility, and ATR-based position sizing for a crypto asset ## Facts - Endpoint: GET https://tasignal.agentgate.workers.dev/v1/risk?utm_source=zero.xyz - Price: $0.02/call - Payment: x402 - Status: unknown - Last checked: 2026-10-28 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/tasignal-risk-analytics-dd7004f9 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_O5DAgJhlrdmUkcqQFva_1 Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability tasignal-risk-analytics-dd7004f9 ``` Example prompt: Give me a full risk breakdown for ETH on 4-hour candles — VaR, CVaR, max drawdown, Sharpe, Sortino, and position sizing for a $10,000 account going long with 1% risk and a 2 ATR stop. ## When to prefer this Use this endpoint when you need quantitative risk metrics and position sizing for a crypto asset trade — specifically VaR/CVaR, drawdown, Sharpe/Sortino, and ATR-based unit sizing. Prefer this over general technical indicator endpoints when the primary goal is risk quantification and trade sizing rather than signal generation. It is especially useful for pre-trade risk checks, portfolio monitoring, or systematic risk management workflows that require historical simulation-based metrics rather than rule-based signals. ## Known failure modes - Missing required 'symbol' parameter returns a 400 validation error - Unknown or delisted symbol returns an error if Hyperliquid and dYdX both lack candle data - Too few candles available for the requested 'bars' count may reduce statistical reliability - Invalid 'timeframe' value (not 15m/1h/4h/1d) returns a schema validation error - If both Hyperliquid and dYdX v4 data sources fail, the endpoint returns a data-unavailable error - Providing a stop price that is on the wrong side of entry (e.g., stop above entry for a long) may produce unexpected position sizing results ## How this service works Technical analysis, risk analytics and backtests for trading agents in one x402 API: RSI, MACD, EMA 20/50/200, Bollinger Bands, ATR, ADX, stochastic, realized volatility and a descriptive technical bias score for any crypto asset on 15m/1h/4h/1d candles; historical VaR/CVaR, max drawdown, Sharpe/Sortino and ATR-based position sizing; and rule backtests (SMA/EMA cross, RSI reversion, Donchian breakout, MACD cross) with fees, next-open fills, trade list and equity curve. Candles from Hyperliquid with dYdX v4 fallback. Read-only analytics; free preview and remote MCP. Not financial advice. Not financial advice. Past performance does not guarantee future results. Technical indicators, risk metrics and backtests describe historical prices only; they are not predictions or trade recommendations. TASignal never trades, holds funds or keys. ## Output A JSON object containing: historical risk metrics (VaR at 95/99% for 1-day and per-bar, CVaR at 95/99%, max drawdown, current drawdown from high, Sharpe/Sortino ratios, annual volatility, period return, best/worst bar), ATR(14) and ATR%, position sizing details (units, notional USD, stop price, stop distance, implied leverage, 2R and 3R take-profit levels, risk in USD), plus metadata (symbol, timeframe, candles used, data source, confidence level, and disclaimer). ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET" ], "type": "string" }, "queryParams": { "type": "object", "required": [ "symbol" ], "properties": { "bars": { "type": "integer", "description": "Candles for risk metrics, 50-1000 (default 500)" }, "side": { "enum": [ "long", "short" ], "type": "string", "description": "Position side (default long)" }, "stop": { "type": "number", "description": "Stop price (optional; overrides stop_atr)" }, "entry": { "type": "number", "description": "Entry price (default: last price)" }, "symbol": { "type": "string", "description": "Base asset ticker, e.g. BTC, ETH, SOL, HYPE (BTC-PERP, ETH-USD and SOLUSDT are accepted too)" }, "risk_pct": { "type": "number", "description": "Percent of the account risked if the stop is hit (default 1)" }, "stop_atr": { "type": "number", "description": "Stop distance in ATR(14) multiples when no stop is given (default 2)" }, "timeframe": { "enum": [ "15m", "1h", "4h", "1d" ], "type": "string", "description": "Candle timeframe: 15m, 1h, 4h or 1d (default 1h; risk default 4h)" }, "account_usd": { "type": "number", "description": "Account size in USD (optional; enables units, notional, leverage)" } }, "description": "Search intents: crypto var api, volatility api, position sizing calculator, max drawdown, sharpe ratio crypto, risk management api" } }, "additionalProperties": false }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "type": "string" }, "example": { "type": "object", "properties": { "risk": { "type": "object" }, "tier": { "type": "string" }, "atr_14": { "type": "number" }, "market": { "type": "string" }, "source": { "type": "string" }, "symbol": { "t … (truncated) ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "risk": { "bars": 499, "method": "historical simulation on closed-candle simple returns; 1-day VaR scaled by sqrt(time); Sharpe/Sortino use a 0% risk-free rate", "best_bar_pct": 8.496, "sharpe_annual": 2.4, "var_95_1d_pct": 3.415, "var_99_1d_pct": 7.281, "worst_bar_pct": -4.03, "sortino_annual": 3.914, "max_drawdown_pct": -15.882, "period_return_pct": 27.347, "var_95_per_bar_pct": 1.394, "var_99_per_bar_pct": 2.972, "cvar_95_per_bar_pct": 2.237, "cvar_99_per_bar_pct": 3.406, "volatility_annual_pct": 49.18, "current_drawdown_from_high_pct": -13.65 }, "tier": "risk", "atr_14": 36.160089, "market": "ETH", "source": "hyperliquid", "symbol": "ETH", "atr_pct": 1.517, "timeframe": "4h", "checked_at": "2026-10-22T19:00:54.578Z", "confidence": "high", "disclaimer": "Not financial advice.
