## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability nonvisceral-eloisa-mousily-ngrok-free-dev-ce9a7e10
```

Example prompt: What's the current bull or bear regime signal for BTC and ETH right now, including the directional confidence score for each?

## When to prefer this

Use this endpoint when you need a simple, pre-computed directional regime label (LONG/SHORT) for BTC and ETH without building your own EMA logic. Ideal for momentum-following strategies, regime-aware position sizing, or confirming trend direction before entering a trade. Prefer this over raw OHLCV feeds when you want a ready-to-use signal rather than raw price data. Pair with sibling liquidation cascade or funding rate endpoints for a fuller market picture.

## Known failure modes

- Service unavailable if the ngrok tunnel is offline or expired
- Stale data if the hourly EMA computation job has not run recently
- Low confidence scores (near 0.33) indicating weak or indeterminate trend — not a failure but a signal to treat cautiously
- 402 Payment Required if the x402 micropayment header is missing or invalid
- Rate limiting or timeout if the upstream exchange data feed is delayed
