## 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 arbipulsestablecoinfxpremium-4f55c1e4
```

Example prompt: What's the current USDT street-price premium over the official rate in Argentina right now — give me the venue table, the median street rate, the premium percentage, and the signal read including blue, MEP, and CCL boards.

## When to prefer this

Use this endpoint when you need real-time, venue-level stablecoin parallel-rate premium data for Latin American capital-controlled economies, especially when the official rate diverges significantly from street prices. Prefer over generic FX APIs when you need the crypto/stablecoin dimension of parallel market rates, or when you specifically need Argentine blue/MEP/CCL board breakdowns alongside the USDT premium signal.

## Known failure modes

- Unsupported currency code returns 400 or empty result
- Live quote fetch timeout if underlying exchange sources are unavailable
- Payment not confirmed returns 402 Payment Required
- Rate-limit exceeded returns 429

## How this service works

Stablecoin parallel-rate premium — how far the street price of a digital dollar (per-venue USDT quotes) diverges from the official FX rate in capital-controlled economies: venue table, median street rate, premium %, signal read. ARS, VES, BRL, COP, PEN, MXN, CLP, BOB; ARS includes the blue/MEP/CCL board. Live quotes, no LLM.

## Output

Returns a table of per-venue USDT quotes, the median street rate, the premium percentage above the official FX rate, and a signal read for the requested country. For ARS, also includes blue, MEP, and CCL parallel board rates. Data is live and not LLM-generated.
