• get_all_source_biases open 34m ago

  Get a page of news-source bias scores. Returns sources active within the last 36 days with >100 articles analyzed, sorted by avg_social_shares descending. The response also includes total, offset, limit, has_more, and one shared bias_score_methodology block. 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 source weighted display score (-50 to +50 for bipolar, 0 to +50 for unipolar). Keys use the same canonical names as get_bias_from_url where a source aggregate is available, but article scores use -10 to +10 or 0 to 10. Compare direction directly; normalize before comparing magnitude. Political / ideological (bipolar: neg=left pole, pos=right pole): 'liberal conservative bias' neg=liberal, pos=conservative 'populist elitist bias' neg=populist, pos=elitist 'libertarian authoritarian bias' neg=libertarian, pos=authoritarian 'dovish hawkish bias' neg=dovish, pos=hawkish 'establishment bias' neg=anti-establishment, pos=pro-establishment Credibility / quality (bipolar): 'overall credibility' neg=low credibility, pos=high credibility 'integrity bias' neg=low integrity, pos=high integrity 'article intelligence' neg=low intelligence, pos=high intelligence 'delusion bias' neg=truth-seeking, pos=delusional 'objective subjective bias' neg=objective, pos=subjective 'objective sensational bias' neg=objective, pos=sensational 'descriptive prescriptive bias' neg=descriptive, pos=prescriptive 'bearish bullish bias' neg=bearish, pos=bullish 'optimistic pessimistic bias' neg=pessimistic, pos=optimistic 'interesting' neg=boring, pos=interesting 'emotional bias' neg=negative tone, pos=positive tone 'rational irrational bias' neg=rational, pos=irrational 'corporate bias' neg=anti-corporate, pos=pro-corporate 'science superstition bias' neg=scientific, pos=superstitious 'individualist collectivist bias' neg=individualist, pos=collectivist Unipolar bias dimensions (higher = more of that trait): 'opinion bias' opinion vs informative 'political bias' political content 'fearful bias' fear-based framing 'overconfidence bias' overconfidence 'gossip bias' gossip 'manipulation bias' manipulative framing 'ideological bias' ideological rigidity 'conspiracy bias' conspiracy content 'double standard bias' double standards 'virtue signal bias' virtue signaling 'oversimplification bias' oversimplification 'appeal to authority bias' appeal to authority 'begging the question bias' question-begging 'victimization bias' victimization framing 'terrorism bias' terrorism content 'fraud bias' fraud-promoting framing 'marxism bias' Marxist framing 'islamist bias' Islamist framing 'anti-semitism bias' anti-Jewish framing 'anti-lgbt bias' anti-LGBT framing 'racism bias' racist framing 'anti-enlightenment bias' regressive, anti-liberal content 'scapegoat bias' scapegoating 'hypocrisy bias' hypocrisy 'suicidal empathy bias' suicidal-empathy framing 'cruelty bias' cruelty 'woke bias' woke framing 'written by AI' AI-written likelihood 'immature bias' immaturity 'circular reasoning bias' circular reasoning 'covering the response bias' covering-the-response tactic 'spam bias' spam-like content 'advertising bias' advertorial or promotional content 'speculation bias' speculation or forecasting 'big pharma bias' reflexive trust in medical/pharma authority Tip: use get_source_bias for full narrative descriptions and recent articles on a specific source. Tip: bias_values use shared canonical names where available. Source and article score scales differ, so normalize magnitudes. get_source_bias exposes the same canonical keys in bias_values and retains emoji-prefixed bias_scores only for backward compatibility. Args: limit: Sources to return (1-1000, default 200). offset: Number of sources to skip for pagination (default 0).

• search_news open 34m ago

  Search news articles. Returns a list of matching articles. Each article includes: - article_id, classification_id, title, source, date, link, category, rank, total_shares, summary - bias_values: dict of per-dimension bias scores using plain-text keys (e.g. 'liberal conservative bias'), same schema as get_bias_from_url and get_all_source_biases (when available) - bias_analysis_status: 'evidence_ready', 'evidence_unverified', 'evidence_partial', 'evidence_failed' (all scored dimensions' quotes failed verification, so the scores do not match the article text), 'scored_legacy', or 'pending' - evidence_ratio: fraction of scored bias dimensions whose supporting quote is verified (0.0-1.0). Raise min_evidence to demand only articles with verified quotes. - bias_dimensions when include_evidence=true: a self-contained object joining each score, scale, evidence status, claim, evidence, counterevidence, confidence, and rationale. Quotes include verification method and exact character offsets when raw-text matching succeeds. Dimension evidence_status is one of: verified, provided_unchecked, quote_mismatch, metadata_incomplete, metadata_only, or missing. - bias_analysis: contract/schema/model/prompt provenance, generation and review status, input scope/hash/size, limitations, quote-verification method, and explicit evidence coverage - context: AI-generated contextual background for the article (when available) - implicit_assumptions: tacit or unstated premises the article's claims or framing rely on (list of concise strings, when available) - extracted_data: structured quantitative/qualitative facts extracted from the article - raw_data: legacy serialized form of extracted_data Args: query: Optional search keywords. Leave empty to return the most recent articles in scope (use with bias to rank them). e.g. 'NVDA earnings'. limit: Max results (1-100, default 20). source: Filter by source name, e.g. 'CNN', 'Reuters'. category: Filter by category. One of: 'trending', 'tech', 'markets', 'politics', 'business', 'science', 'memes'. days_back: Only include articles from the last N days. 0 means no date filter. Default: 90. Widen this (e.g. 720) for older coverage. min_shares: Minimum total social shares. sort: Sort order. One of: 'rank' (relevance, default), 'date' (newest), 'shares' (most shared). bias: Bias dimension to rank by, highest score first. This is a ranking, not a standalone filter: an empty query still returns other recent articles, ranked with the bias dimension on top. Any canonical bias key, e.g. 'liberal conservative bias', 'overall credibility', 'conspiracy bias'. Ranking is scoped to recent articles (the days_back window, or 365 days when days_back is 0) so one old high-scoring outlier cannot dominate. include_evidence: Include claim-level evidence, counterevidence, confidence, rationale, and limitations. Defaults to false to keep search payloads compact. only_analyzed: Return only articles with valid canonical bias scores. min_evidence: Minimum fraction of scored dimensions with verified quotes (0.0-1.0, default 0). Raise this to request only articles whose scores are backed by verified evidence, e.g. 0.5. Pair it with only_analyzed to get quotable results instead of pending records with empty bias_values. Returns a 400 if sort or bias is not a valid option.

• get_option_price unknown never probed

  Get Helium's proprietary ML model-predicted price for a specific option contract. Helium trains per-symbol regression models on historical options data. This tool looks up the most recent available options chain for the symbol (today or up to 5 days back), finds the exact contract matching strike/expiration/type, and runs it through that model to produce a predicted fair-value price. Returns: - symbol: the ticker - strike: the strike price used - expiration: the expiration date used - option_type: 'call' or 'put' - predicted_price: Helium's model-predicted option price in dollars - prob_itm: probability of expiring in the money (0.0–1.0), or null if model unavailable - options_data_date: the date of the options chain snapshot the model was run on (so you know how fresh the underlying market data is) Throws an error if no options chain data is available for the symbol within the past 5 days, or if the exact contract (strike/expiration/type combination) does not exist in that chain. Args: symbol: Ticker symbol, e.g. 'AAPL', 'SPY'. strike: Strike price as a number, e.g. 150.0. expiration: Expiration date as 'YYYY-MM-DD', e.g. '2026-06-20'. option_type: Must be 'call' or 'put'.

• get_bias_from_url unknown never probed

  Get bias analysis for a specific article by its URL. Use this when you have a direct link to an article and want to know its political leaning, credibility, emotionality, and other bias dimensions — without needing to know the source name first. On success (found=true), returns: - article_id, classification_id, requested_url, matched_url, title, source, date, link, category - teaser: article excerpt - summary: one-sentence AI summary - context: AI-generated context for the article - implicit_assumptions: tacit or unstated premises the article's claims or framing rely on (list of concise strings, when available) - extracted_data: structured quantitative/qualitative facts extracted from the article - raw_data: legacy serialized form of extracted_data - bias_description: narrative description of this specific article's bias - bias_values: dict of per-dimension article scores using canonical plain-text keys, e.g. {"liberal conservative bias": 4, "overall credibility": 7, "emotional bias": -5, ...} Article scores use -10 to +10 for bipolar dimensions and 0 to 10 for unipolar dimensions. Positive values lean toward the second pole of each dimension (conservative, authoritarian, etc.). - bias_analysis_status: 'evidence_ready', 'evidence_unverified', 'evidence_partial', 'evidence_failed' (all scored dimensions' quotes failed verification, so the scores do not match the article text), 'scored_legacy', or 'pending' - bias_dimensions when include_evidence=true: each dimension's score, scale, evidence status, claim, verbatim evidence, counterevidence, confidence, and rationale. Quotes include verification method and exact character offsets when raw-text matching succeeds. Dimension evidence_status is one of: verified, provided_unchecked, quote_mismatch, metadata_incomplete, metadata_only, or missing. - bias_analysis: contract/schema/model/prompt provenance, generation and review status, input scope/hash/size, analysis target, quote-verification method, explicit missingness and evidence coverage, and case-specific limitations - total_shares: total social shares - wayback_link: Wayback Machine archive URL if available - image: article image URL if available On failure (found=false, HTTP 404): - found: false - message: explanation string The URL is automatically queued for ingestion; retry after ~24 hours. Tip: if you want source-level bias (not article-level), use get_source_bias instead. Tip: bias_values keys here use plain-text format (e.g. 'liberal conservative bias') shared with the other bias tools where that dimension is available. Args: url: Full article URL, e.g. 'https://www.nytimes.com/2024/01/01/us/politics/example.html'. include_evidence: Include claim-level evidence and limitations. Defaults to true.
