Example prompt: What's the current WaveTrend 4-hour signal for SOL on Kraken — give me the wt1 and wt2 values, the previous readings, and whether there are any recent oversold or overbought band dots?

## When to prefer this

Choose this endpoint when you need a quick, cheap WaveTrend technical signal for any coin/USD pair on Kraken beyond BTC, or when you want the cheapest available WaveTrend snapshot at $0.002 USDC per call. Prefer this over the BTC-specific sibling when querying altcoins. Use when you need oscillator momentum context without a full charting pipeline.

## Known failure modes

- Unsupported coin symbol returns an error or empty result
- Kraken data feed unavailable causes fetch failure
- Invalid path parameter format returns 4xx error
- Symbol not listed on Kraken USD pairs returns no data
- x402 payment not fulfilled results in 402 response blocking data delivery
