get_all_source_biases
Retrieve bias scores for active news sources to analyze media credibility, identify political leanings, and compare outlets across multiple ideological and quality dimensions.
Instructions
Get bias scores for every news source in the Helium database.
Returns a list of all sources (active within the last 36 days, with >100 articles analyzed),
sorted by avg_social_shares descending. Use this to compare sources, find the most credible
outlets, identify politically extreme sources, or build a ranked overview of the media landscape.
Each entry contains:
- source_name, slug_name, page_url
- articles_analyzed: total articles analyzed for this source
- avg_social_shares: average social shares per article (proxy for reach/influence)
- emotionality_score (0-10): average emotional intensity of the writing
- prescriptiveness_score (0-10): how much the source tells readers what to think/do
- bias_values: dict mapping classifier key → integer score (-50 to +50 for bipolar,
0 to +50 for unipolar). These keys are identical to what get_bias_from_url returns,
so you can compare article-level and source-level scores directly.

Tip: use get_source_bias for full narrative descriptions and recent articles on a specific source.
Tip: bias_values keys here are identical to those in get_bias_from_url and search_news — compare them directly.
Warning: get_source_bias returns bias_scores with emoji-prefixed display keys (e.g. '🔵 Liberal <—> Conservative 🔴')
that are NOT interchangeable with the plain-text keys used here. Do not cross-reference them.Input Schema
