Quick examples

Rates by ExchangeRate-API

What the response contains

ExchangeRate-API’s open endpoint returns a base currency, rates, and update times. It can support comparisons and conversion previews when an application retains the date, follows the source attribution requirement, and does not mistake a reference rate for a final transaction price.

Practical use

The open-endpoint documentation states daily updates, rate limiting, and an attribution requirement. The result does not automatically include spread, fees, settlement availability, or a provider’s final quote.

How to use it

Enter a three-letter base currency such as USD, then check base_code, the update times, and returned rates.

Fields worth checking

  • Base currency
  • Last update
  • Next update
  • Rates by currency

Who this helps

People and teams who need an exchange reference with its update date and next update visible.

Where this lookup saves time

  • Shows the base currency, rates, and times returned by the source.
  • Helps present a conversion reference with the date that gives it context.

What the response contains

The route receives a three-letter currency such as USD, EUR, or BRL. The observed response contains result, provider, documentation, terms_of_use, time_last_update_utc, time_next_update_utc, base_code, and rates. It therefore identifies the queried currency, the data update time, the source’s expected next update, and the available rates.

  • Use base_code to identify the currency from which the table starts.
  • Keep time_last_update_utc with any converted amount you display.
  • Read rates as destination currencies and their values for the selected base.

Updates, caching, and attribution

The open-endpoint documentation says data updates once per day, requests are rate limited, and attribution is required. The response itself includes the expected next update. For a stable interface, use that time as context, avoid repeating the same request unnecessarily, and keep the source credit accessible wherever these rates are shown.

  • Show or record the last-update time instead of calling the data simply current.
  • Cache in a way that follows the source terms and treat a 429 response as a reason to slow new attempts.
  • Keep the ExchangeRate-API attribution link on the page that displays this lookup.

Limits before using money

The rates can support comparisons, reports, and estimates. They do not confirm the amount a bank, card issuer, broker, or exchange service will apply, because the final price can include spread, fees, execution timing, and transaction-specific conditions.

  • Confirm the amount directly with the provider before paying, sending money, or signing a contract.
  • Do not present a reference rate as financial advice or a guaranteed outcome.
  • Read the official documentation and terms before relying on the source in a critical commercial flow.
