Postali
Postali is a free, keyless postal/zip-code API covering Mexico, Colombia, and Spain — a single curl call against /api/v1/{country}/cp/{code} returns the state, municipality, and neighborhood(s) for a code, sourced from SEPOMEX (Mexico) and GeoNames (Colombia/Spain). It runs on Rust + SQLite served from Cloudflare's edge, with no card, login, or rate-limit gate — the only ask is a courtesy link back if used in a public project.
