## When to prefer this

Use this endpoint when you need a real-time, pre-computed VWAP reversion signal specifically for DOGE and want a low-cost ($0.001 USDC) per-call micropayment model via x402. Prefer this over building your own VWAP calculation when you need fast, arena-style strategy signals for algorithmic or agent-driven trading decisions.

## Known failure modes

- Ticker not supported — 404 if DOGE is unavailable
- Insufficient market data — signal may return null or low-confidence
- Payment not accepted — 402 if x402 micropayment fails
- Service unavailable — 503 if Railway deployment is down
