## 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 agent-signals-jp-crypto-price-cryptojp-com-404d8671
```

Example prompt: What's the current BTC price in Japanese yen right now, including how it compares across bitflyer and coincheck?

## When to prefer this

Use this endpoint when you need real-time crypto prices denominated in JPY from Japanese exchanges (bitflyer, coincheck), or when you need USD/JPY rate alongside crypto prices for arbitrage, regulatory, or regional market-intelligence purposes. Prefer this over generic global price feeds when Japan-specific venue data or JPY pricing is required.

## Known failure modes

- Invalid or unsupported symbol returns an error (e.g. unsupported asset not listed on JPY venues)
- Payment failure via x402 if USDC balance is insufficient
- Network timeout if Japanese exchange data is momentarily unavailable
- Missing required 'symbol' query parameter returns a 400-level error

## How this service works

Pay-per-call crypto market-intelligence API for autonomous AI trading agents. Funding-rate, BTC lead-lag and trend/chop regime signals, settled in USDC over x402.

## Output

A JSON object containing: ok status, base asset symbol, USD/JPY rate, per-venue JPY prices (e.g. bitflyer, coincheck), aggregated JPY price, cross-venue spread percentage, and USD equivalent price.
