Example prompt: What's the current fused directional trading signal for ETH right now, and how confident is it?

## When to prefer this

Use this endpoint when you need a single, pre-fused directional signal for ETH with an attached confidence score, rather than assembling raw indicators yourself. Ideal for automated trading agents that need a quick actionable bias (buy/sell/neutral) for Ethereum without building their own signal fusion pipeline.

## Known failure modes

- Asset not supported — returns 404 or error if a non-supported symbol is queried
- Payment failure — 402 if x402 USDC payment of $0.01 is not provided or fails
- Rate limiting — 429 if too many requests are made in a short period
- Service unavailable — 503 if signal computation is temporarily offline
- Stale data — signal may lag real-time market conditions during high volatility
