Verdict

An official national weather and seismic source for Portugal, alongside met-norway-weather-api. Non-commercial warning: IPMA's conditions of use say "O Utilizador pode copiar, importar ou utilizar gratuitamente informações ou símbolos nacionais existentes neste site para uso pessoal ou público desde que dessa utilização não decorram finalidades lucrativas ou ofensivas." and "O Utilizador deve referir, sempre, a fonte de informação." In short: free personal or public use only where it has no profit-making or offensive purpose, and always cite the source. Licence: Custom (no open-data licence named). The conditions, read with plain curl, set no rule against software reading the public API. Rate limits: Not stated. Signal Lab links only.

Ask your agent

Fetch https://signal-lab.qdt.ai/catalog.json, find slug "ipma-open-data-api" and read its licenseNote. IPMA's conditions of use say the information on its site may be copied, imported or used free of charge for personal or public use only where that use has no profit-making or offensive purpose, and that the source must always be cited. So do not write a commercial loader for this API. If my use is personal or public and non-commercial, link me to the official IPMA open-data index at https://api.ipma.pt/open-data/ so I can read the forecasts, warnings and seismic data myself, tell me to always cite IPMA as the source, and tell me to ask IPMA before any commercial use.
