## 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 npb-asian-handicap-oracle-671813c4
```

Example prompt: Pull the NPB Asian handicap oracle data for June 15, 2025 — I want to see the handicap lines and predictions for all Japanese baseball games that day.

## When to prefer this

Use this endpoint when you need Asian handicap-specific oracle outputs for NPB games (not just win probabilities), particularly for sports betting analysis or handicap line research on Japanese professional baseball. Choose this over the NPB win probability endpoint when handicap spread data is the primary requirement.

## Known failure modes

- Invalid date format (not YYYY-MM-DD) returns a 400 validation error
- No NPB games scheduled on the requested date returns empty or null data
- Date too far in the future with no available oracle data
- Service unavailable or upstream oracle data not ready returns 5xx
- Payment not provided or invalid x402 payment header returns 402
