## 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 try-madhousewallet-com-15011f7d
```

Example prompt: What's the current FX rate and how much would my recipient actually receive in Nigerian naira (NGN) if I send $500 USD through Madhouse Wallet?

## When to prefer this

Use this endpoint when you need to show a user the exact payout amount and fee breakdown before committing to a cross-border transfer. It supports 80+ currencies and is the required first step before calling the transfer creation endpoint — the returned quoteId locks in the rate for downstream use.

## Known failure modes

- Unsupported targetCurrency returns an error — only 80+ supported ISO 4217 codes are valid
- sourceAmount of 0 or above 1,000,000 returns a validation error
- Missing required query parameters (targetCurrency or sourceAmount) returns a 400-level error
- Payment of 0.01 USDC not provided triggers a 402 Payment Required response
- Network or provider outage may return a 500-level error with no quote data

## How this service works

Convert USDC to 45+ local currencies and receive funds directly to your bank account. Fast, secure crypto offramp powered by Madhouse Wallet.

## Output

Returns a quoteId (used to create a transfer), the echoed sourceAmount and targetCurrency, the USD-to-target exchange rate, a quote object with targetAmount (what the recipient receives), transferFee in USD, fee breakdown fields (feeFxPercent, feeFxAmount, feePayoutAmount), and estimatedDelivery timestamp. Some fee fields may be null.
