apexquant-news-datasources

Official Arithmion news data-source plugins. This is a pip plugin, not a bundled/built-in datasource — it ships independently of the main Arithmion app and is discovered at runtime through Arithmion's apexquant.datasources entry-point group, the same mechanism used by apexquant-example-datasource.

Providers

Each provider is its own TextSource subclass, registered as its own apexquant.datasources entry point — no aggregator, no forced bundling. Consume them individually via make_text_source("<entry point>"), or call several and combine the results yourself.

Set only the env vars for the providers you actually use; none are required unless you instantiate that specific provider.

Reference, not derived

This package's provider list and field design took inspiration from how FinceptTerminal and OpenBB shape their own news data — which providers to support, how to normalize fields across them. No code, package, or runtime dependency from either project is used here. Both are AGPL-3.0 (FinceptTerminal is additionally dual-licensed, requiring a paid commercial license for any business use, "paid or free," regardless of whether the software embedding it is itself open source) — reference-only use avoids that entirely. The full rationale is recorded as an Architecture Decision Record in the main Arithmion repository (docs/adr/0007-新闻插件仅参考-openbb-fincept-不依赖其代码.md).

Install

pip install apexquant-news-datasources

This plugin's only required dependency is arithmion-core — the published interface tier of the Arithmion platform (it ships the apexquant import namespace TextSource/TextDocument/etc. are defined in).

Each provider is BYO-key (bring your own API key) via an environment variable — no credentials are bundled or proxied. Providers requiring a heavier optional dependency (e.g. yfinance) ship behind an extra:

pip install "apexquant-news-datasources[yfinance]"

Development

pip install -e ".[test]"
pytest
