## When to prefer this

Choose this endpoint when you need a real-time, quantitatively derived event risk signal for a specific equity ticker — especially for algorithmic trading strategies that react to earnings, macro events, or other scheduled catalysts. Prefer this over general market data feeds when event-specific risk scoring is required rather than raw price or volume data.

## Known failure modes

- Invalid or unrecognized ticker symbol returns 404 or error payload
- Payment not received or x402 payment verification fails returns 402 Payment Required
- Ticker outside supported universe returns empty or null signal
- Rate limits exceeded returns 429
- Market closed or no active event context may return low-confidence or null signal

## How this service works

Real-time quantitative signals for algorithmic trading, gated via the x402 payment protocol.

## Output

A quantitative event risk signal for the specified ticker, likely including a risk score or magnitude, signal metadata, and timing context relevant to upcoming market events — returned in real-time for use in algorithmic trading logic.
