IPMA-API

This PHP package provides an easy-to-use interface for the IPMA (Instituto Português do Mar e da Atmosfera, I. P.) API. It allows you to fetch weather forecasts, observation data, and other auxiliary information directly into your PHP application.

For more information about the official API, please visit https://api.ipma.pt/ (only in Portuguese).

[!IMPORTANT] This package is unofficial and IS NOT affiliated with, endorsed by, or maintained by Instituto Português do Mar e da Atmosfera, I. P. (IPMA, I.P.) It only provides a PHP client for the public API available at https://api.ipma.pt/.

Warning: This is a work in progress package! While it is actively maintained, some features may be incomplete or subject to change.

Getting Started

Prerequisites

• PHP 8.1 or higher
• Composer

Installation

composer require tuxonice/ipma-api

Usage

Heads up — breaking change: every factory now requires a PSR-16 Psr\SimpleCache\CacheInterface. This is intentional: IPMA asks consumers not to hammer their endpoints, and most of them change infrequently (locations, stations, forecasts). See Caching responses (PSR-16) below for setup.

Here are a few examples of how to use this package. All snippets assume $cache is a Psr\SimpleCache\CacheInterface instance (e.g. a Symfony\Component\Cache\Psr16Cache backed by any PSR-6 adapter).

Get Daily Weather Forecast

Get Seismic Information

Get Weather Stations (Service)

All endpoints now return typed DTOs under Tlab\IpmaApi\Dto\*:

For more detailed examples and a full list of available endpoints, please see the documentation folder.

Caching responses (PSR-16)

IPMA asks consumers to avoid hitting their endpoints too often. To enforce this, a PSR-16 Psr\SimpleCache\CacheInterface is required by every factory and by ApiConnector itself — there is no unbounded-request mode.

Any PSR-16 implementation works. Using symfony/cache as an example:

Every factory accepts an optional int $ttlSeconds = 3600 as its second argument. You can also construct the connector directly:

Both JSON (fetchData) and CSV (fetchCsv) responses are cached. The raw CSV string is stored in cache and reconstructed as a Reader on hit. Cache keys are namespaced as ipma_api.<sha256(url)>.

Migrating from previous versions

• Tlab\IpmaApi\CachedApiConnector has been removed. Its caching behaviour is now built into ApiConnector.
• new ApiConnector() (no arguments) no longer works: you must pass a CacheInterface.
• IpmaForecast::create*Api(), IpmaObservation::create*Api() and IpmaService::create*Api() no longer accept an ApiConnectorInterface; they take (CacheInterface $cache, int $ttlSeconds = 3600) instead.
• The shared lazy default ApiConnector singleton inside the facades has been removed. Instantiate and share your own $cache (and therefore your own connectors) at the composition root.

Error handling

All errors raised by the library extend Tlab\IpmaApi\Exception\IpmaApiException:

• IpmaTransportException — network/TLS/timeout failures.
• IpmaResponseException — unexpected 3xx/4xx/5xx HTTP status.
• IpmaDecodingException — malformed JSON in the response body.
