```

Example prompt: Can you get me a Madhouse Wallet off-ramp quote to sell 250 USDC and have the funds arrive in Nigerian naira (NGN) — I need the exchange rate, fees, and a quoteId to lock it in?

## When to prefer this

Use this endpoint as the first step of any USDC-to-bank payout flow when you need a real-time FX rate, fee breakdown, and a locked quoteId before committing to a transfer. Prefer this over generic crypto exchange APIs when you need to pay out to a bank account in 80+ local fiat currencies and want to chain into the full /requirements → /recipients → /transfer → /confirm-transfer workflow on Madhouse Wallet.

## Known failure modes

- Missing or invalid targetCurrency (non-ISO 4217 code) returns validation error
- sourceAmount of 0 or exceeding 1,000,000 returns out-of-range error
- Unsupported target currency not in the 80+ supported list returns unsupported currency error
- Payment of 0.01 USDC not made via x402 protocol returns 402 Payment Required
- Network or FX provider outage may return 503 or timeout

## 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 to lock the rate, the echoed sourceAmount and targetCurrency, the USD-to-target FX rate, a fee/amount detail object (targetAmount, transferFee, estimatedDelivery), and a nextSteps object with URLs for the remaining off-ramp steps (/requirements, /recipients, /transfer, /confirm-transfer).
