Output

Some fee fields may be null.

Technical details
Endpoint
GEThttps://try.madhousewallet.com/api/public/quoteWhen to prefer
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.
Side effects
- 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
