ESA Space Weather HAPI Server

Heliophysics Application Programmer's Interface (HAPI) server providing access to ESA Space Weather Service Network data. Implements the COSPAR-recommended HAPI standard for streaming heliophysics time-series data. Endpoints include catalog (dataset listing), info (parameter definitions), data (time-range streaming), capabilities, and about. Authentication requires an ESA SSO M2M client-id/secret pair exchanged for a short-lived Bearer token (expires 300 seconds) via https://sso.s2p.esa.int/realms/swe/protocol/openid-connect/token.
