How this service works
Everything in /bundle/market-brief (regime, sentiment, price, risk) plus an AI-generated synthesis connecting the signals and naming the single biggest risk factor — grounded only in the real data returned, never fabricated. For agents wanting one $2.50 call instead of a market brief plus a manual read. Input: ?symbol=SOL. Output: {symbol, regime, sentiment, price, risk, generated_at, disclaimer, analysis: {synthesis, key_risk}}.
Output
A JSON object containing: current price with 24h/7d percentage changes and a bullish/bearish/neutral signal; sentiment score (-1 to 1) with label; volatility metrics (ATR percentage, ATR 80th-percentile 30-day baseline) and a drawdown risk rating; market regime classification (chop, trend_up, trend_down, high_vol) with ATR and EMA spread features; a grid suitability verdict with explanatory note; a synthesized narrative summary and key risk warning; and a generated_at timestamp. All wrapped with an educational disclaimer.
Example use cases
Pre-trade crypto regime check
“Before I deploy my grid bot on ETH, pull the deep signal bundle — I want to see the current regime, volatility level, grid suitability verdict, and overall sentiment.”
Daily crypto dashboard briefing
“Give me the full deep signal analysis for BTC right now — price change, bullish or bearish signal, how volatile it is compared to its 30-day baseline, and a plain-English synthesis of what the market is doing.”
Automated risk-gated trading decision
“Check the deep signal for XRP and tell me if drawdown risk is low and the regime is chop or trending up before I place any orders today.”

Endpoint
GEThttps://api.stelardigital.com/bundle/deep-signal?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a holistic, all-in-one market read for a supported crypto asset and want to avoid making five separate calls to price, sentiment, regime, volatility, and grid-param endpoints. Ideal for agents orchestrating trading decisions, dashboard briefings, or risk checks where latency budget allows one slightly heavier call. Prefer individual sibling endpoints only when you need a single signal in isolation or want to minimize per-call cost.
Side effects
- Unsupported symbol passed (must be one of ADA, BTC, DOGE, ETH, LTC, SOL, XLM, XRP) — likely 400 or validation error
- Payment not included or insufficient — 402 Payment Required
- Upstream data source unavailable — may return stale or partial data
- Network timeout on real-time price or sentiment feed — 500 or timeout error
