okboolean

Request-level success flag, independent of the HTTP status.

valornumber

The figure itself, already a percentage — 2.855 means 2.855 percent.

messtring

The month the fixing belongs to, in Spanish. Usually the previous month, since these publish in arrears.

actualizadostring

ISO timestamp of when Casheva last refreshed the value.

fuentestring

Source attribution.

condicionesstring

Licence text stating the attribution requirement. Read it before shipping.

interanual / mensualnumber

On the inflation endpoint, year-on-year and month-on-month rates with their own reference dates.

• Feed the current Euribor into a Spanish variable-rate mortgage calculator
• Show Argentine year-on-year inflation on a dashboard
• Apply Spain's ICL index to a rental increase calculation
• Compare advertised fixed-deposit rates against a published benchmark

If Casheva does not fit, these finance & crypto apis cover similar ground. Every one was called before publishing, and each links to its own reference page with a working curl command and the response it returned.
