Output
A JSON object containing: the signal tier ('fast'), a directional signal string (e.g. 'BULLISH'), the data source ('NEXUS_FAST'), the queried symbol (e.g. 'BTC'), and a confidence score between 0 and 1 (e.g. 0.55).
Example use cases

“Hey, before I make any moves, can you pull the fast signal for BTC and tell me if it's bullish or bearish right now and how confident we should be in that call?”
ETH sentiment before rebalancing portfolio
“I'm about to rebalance my portfolio — what's the current directional signal for ETH? Is the model leaning bullish or bearish, and what's the confidence score?”
Solana signal for automated trade trigger
“Check the fast-tier market signal for SOL for me — I want to know if it's bullish, bearish, or neutral and what confidence level is attached before I trigger anything.”

Endpoint

- Service unavailable — hosted on Render free tier, cold starts may cause timeouts
- Missing required query parameter — omitting symbol may result in a missing or malformed response
