Rounding rules for money

In short

This is one of the questions we hear most from developers integrating currency data. Below is the short answer, followed by a one-line example you can try today.

Try it

curl "https://rate-api.com/api/v1/latest?base=USD&symbols=EUR" \
  -H "X-API-Key: YOUR_KEY"

Look at the timestamp field: it tells you exactly when the rate was set, which is the key to reasoning about freshness.
