## When to prefer this

Use this endpoint when you need official, bank-grade VND exchange rates specifically from Vietcombank — Vietnam's most authoritative FX source — especially for remittance applications, travel pricing, or financial products serving the Vietnamese market. Prefer this over generic FX APIs when you need the cash buy vs transfer buy vs sell rate breakdown that Vietnamese banks publish, or when regulatory/compliance context requires citing an official Vietnamese bank rate.

## Known failure modes

- Invalid currency code returns empty result or 400 error
