## 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 fiat-rails-by-country-88c7905d
```

Example prompt: Before I show the buy-crypto flow to my users, check what Coinbase fiat on-ramp rails — card, bank transfer, cash-out options — are actually available in Brazil, including the supported currencies and deposit limits.

## When to prefer this

Use this endpoint when you need a pre-flight feasibility check before presenting fiat payment options to a user in a specific country — it tells you exactly which rails exist (card, bank transfer, cash-out) and their limits, preventing failed user flows. Prefer this over generic payment provider docs when building integrations that need runtime country-level routing logic, especially when distinguishing card-capable markets from crypto-transfer-only markets.

## Known failure modes

- Missing or invalid ISO country code returns an error
- Country not in the 122-country coverage list returns empty or unsupported result
- Network timeout if upstream Coinbase data is temporarily unavailable
- Stale data if Coinbase has recently changed rails in a country without cache invalidation

## How this service works

🆕 The feasibility check before you ask a user for money: which fiat-in and cash-out rails Coinbase actually runs in a country, the currencies and min/max limits for each, and how many assets across which networks. Distinguishes a country with card rails from one where crypto can only be transferred in — a difference most integrations discover only after a user fails. 122 countries covered.

## Output

A structured response listing the fiat on-ramp and cash-out rails available in the requested country, the currencies supported per rail, minimum and maximum transaction limits for each, the number of supported crypto assets, and the blockchain networks available — covering up to 122 countries.
