Vietnam Exchange Rates API
Live Vietnamese đồng (VND) bank counter exchange rates from Vietcombank, Vietnam's largest commercial bank. Unlike a central-bank reference or a parallel-market rate, these are the rates a customer actually transacts at, quoted in three forms: the cash rate (buying banknotes), the transfer rate (buying via wire) and the sell rate (the bank selling foreign currency). The rates endpoint returns every quoted currency against the đồng with all three rates and the buy/sell spread; the rate endpoint returns one currency; the convert endpoint converts any amount between a currency and the đồng at the chosen rate. Read live, nothing stored. This is Vietnam's own commercial-bank counter-rate layer — distinct from central-bank reference feeds and from parallel-market APIs.
