## How to call it through Zero

```sh
zero fetch --capability api-carbon-cashmere-de-89cb75bc
```

Example prompt: What's the current AI trading signal for ETH — is it bullish or bearish, and how confident is the 5-model ensemble (XGBoost, LightGBM, LSTM, Random Forest, MetaLearner)?

## When to prefer this

Use this endpoint when you need a single, aggregated ML-based directional signal for a supported crypto asset and want model-level breakdown (not just a single model output). Ideal for algorithmic trading agents, quant strategies, or any workflow that benefits from ensemble consensus and per-model agreement rather than raw price data alone.

## Known failure modes

- Unsupported coin symbol returns 404 or error (only BTC, ETH, SOL, TAO, KAS, XLM, QUBIC supported)
- Payment not included or insufficient USDC results in 402 Payment Required
- Missing or malformed path variable :var1 returns 400 Bad Request
- Model inference latency spike may cause timeout
- Market data feed unavailable causes upstream error
