mostlyrightmd

The full mostlyright SDK in one install.

mostlyrightmd is the meta-distribution: it pulls the core plus every domain package — weather, markets, economy, and finance — so a single command gives you the complete SDK.

The SDK fetches its public sources directly, and the addresses it calls resolve through the hosted manifest catalog, which requires an API key — subscriptions at https://app.mostlyright.md. Call mostlyright.configure(api_key=...), or set MOSTLYRIGHT_API_KEY before the first call; without a key the SDK raises ApiKeyRequiredError before making any request. See docs/api-key.md.

pip install mostlyrightmd

import mostlyright as mr

mr.weather   # live METAR / ASOS archive / GHCNh / NWS CLI
mr.markets   # Kalshi + Polymarket resolvers + settlement
mr.economy      # CPI / PPI / payrolls / GDP with first-print vintages
mr.finance   # earnings-call transcripts + earnings-mention resolution

The PyPI package name is mostlyrightmd; the Python import name is mostlyright. import mostlyrightmd raises a teaching ImportError pointing at import mostlyright as mr — there is no silent alias.

Power users: install one domain

Every domain ships as its own wheel and brings the core transitively, so you can install just what you need:

pip install mostlyrightmd-core       # types + temporal safety + align()/spine()
pip install mostlyrightmd-weather    # weather data sources
pip install mostlyrightmd-markets    # prediction-market resolvers + settlement
pip install mostlyrightmd-economy       # economic indicators + vintages
pip install mostlyrightmd-finance    # earnings-call transcripts + resolution

All domain wheels share the mostlyright.* Python namespace (PEP 420) and bump in lockstep on a single version.
