Does Banxico have a proper REST API? I need to pull USD/MXN exchange rates, TIIE rates, and UDI values for a financial app. I found their SIE (Sistema de Información Económica) portal but it's not clear if there's an API endpoint I can query directly.

Also: how frequently does Banxico publish exchange rate data? Is it real-time or once per business day? And what's the API's authentication model?

Yes, Banxico has a public REST API via their SIE. No auth required for public series. Exchange rates publish once per business day (around 12pm). The API is at api.banxico.org.mx.

Banxico API returns data in a wrapper format with series IDs. SF43718 is USD/MXN FIX rate. Third-party wrappers on apipull.com simplify the data parsing.
