Frequently Asked Questions

  • Yes, but you must have a premium subscription. Commercial use of the LIBOR API is not permitted on the free tier. See our pricing page to choose a plan that fits your needs.
  • Sign up for a free account to instantly get your API key, then pass it in the X-Api-Key header on every request. The documentation above includes ready-to-run examples in cURL, Python, JavaScript, Node.js, and more.
  • Your API requests will simply be denied once you hit your monthly quota — you will never be charged more than the plan you signed up for. To increase your quota, you can upgrade your plan any time on our pricing page.
  • The API responds with a standard HTTP status code and a JSON error message describing the problem. See our error codes reference for the full list of codes and how to resolve each one, or contact support if you need help.
  • LIBOR stopped being published on September 30, 2024, so the API provides a single endpoint, /v1/liborhistorical, which returns the historical time series for a given tenor. The former current-rates endpoint has been retired; see the full API list for related rates.
  • Call /v1/liborhistorical with the required type parameter set to one of overnight, 1_month, 3_months, 6_months, or 12_months, and optionally narrow the range with the start_time and end_time UNIX timestamps (in seconds). A maximum of 100 data points is returned per call; access requires the Business or Professional tier, which you can review on the pricing page.
  • The /v1/liborhistorical endpoint returns a name plus a data array of objects, each containing a timestamp and rate_pct (the rate in percent). For other benchmarks see the Interest Rate API.
  • It is useful for backtesting and analyzing loan, derivative, and bond pricing tied to LIBOR, building historical interest-rate charts, and reconciling legacy contracts that referenced the benchmark before it was discontinued. You can combine it with the Mortgage Rate API or Exchange Rate API for broader financial modeling.
