Government — entry 001 of 90
Bank Negara Malaysia Open Data
Bank Negara Malaysia's OpenAPI developer portal catalogues dozens of free, key-free JSON APIs — exchange rates, interest and lending rates, government securities, and monetary statistics — confirmed live with an anonymous call returning real exchange-rate data with no signup. The documentation site runs on a separate host from the live API itself (api.bnm.gov.my), and its CORS header is allow-listed to BNM's own portal domain rather than reflecting arbitrary origins, so third-party web apps on other domains will be blocked by the browser.
