## 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 nythosx-price-probability-estimator-f048a865
```

Example prompt: What's the probability that BTC hits $90,000 in the next 1, 7, and 30 days, and how many days does it estimate before it gets there?

## When to prefer this

Choose this endpoint when you need a quantitative, probabilistic estimate of whether an asset will reach a specific price level within defined time windows. It is ideal for pre-trade analysis, setting realistic profit or buy targets, and comparing the statistical feasibility of price levels across different timeframes. Prefer this over simple price lookups when the user needs odds or timing estimates, not just the current price.

## Known failure modes

- Unsupported symbol not in the allowed enum causes a 400 or validation error
- Target price set below or at current price may return zero probabilities without an error
- Network or service downtime returns a 5xx error
- Invalid or missing required parameters (symbol, target) returns a 400 bad request
- Extremely distant price targets may return near-zero probabilities that are mathematically valid but practically unhelpful

## How this service works

24/7 price monitoring for crypto, stocks, and forex. Get pinged the second your buy or profit target is reached. Track real P&L in pesos.

## Output

Returns a JSON object with the current price, the percentage move required to reach the target, daily volatility percentage, estimated days until target is reached, and touch probabilities (probability of the price at least touching the target) and close-beyond probabilities (probability of closing above/below the target) for 1-day, 7-day, and 30-day horizons.
