## 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 agenttoll-turkish-crypto-exchange-spread-checker-58147643
```

Example prompt: Can you check the current spread between BTCTurk and Paribu's USDT prices versus the global market price — I want to see how much of a premium USDT is trading at in Turkey right now?

## When to prefer this

Use this endpoint when you need to specifically compare Turkish cryptocurrency exchange prices (BTCTurk, Paribu) against global spot prices with TRY-to-USD conversion. Prefer this over generic price feeds when monitoring emerging market crypto premiums, investigating Turkey-specific arbitrage opportunities, or tracking capital control effects on crypto pricing. The USDT pair is recommended for the most liquid local comparison.

## Known failure modes

- Invalid asset parameter (not 'btc' or 'usdt') returns an error
- BTCTurk or Paribu API unavailability causes incomplete spread data
- Stale or unavailable USD/TRY official rate may affect conversion accuracy
- Payment failure (x402) blocks the request if USDC balance is insufficient

## How this service works

Turkish exchange spread check: BTCTurk and Paribu's TRY quotes converted back to USD via the official rate and compared against the global price; ?asset=usdt is the pair with the deepest local volume

## Output

Returns the TRY-quoted prices from BTCTurk and Paribu for the selected asset (BTC or USDT), converted back to USD using the official USD/TRY exchange rate, alongside the global spot price and the computed spread between local and global prices. The USDT pair has the deepest local volume on Turkish exchanges.
