Coverage blind spots: companies, models, and people that regional press (Chinese/East-Asian, European, Latin-American) is covering while Western/global feeds are not — ranked, with per-region item counts. Answers "what is Western tech media missing right now?". Measured within Horizon's corpus: "invisible" means zero pickup in the Western feeds Horizon tracks, not a claim about all media.
Lookback window in days (default 60, 7–180).
Max entities (default 15, cap 50).

}Shortcut for get_region_signal with region "china": the current China & East-Asia AI signal (Qwen, DeepSeek, Zhipu, Moonshot, ModelScope, and more) that Western feeds often miss — ranked by momentum. Prefer get_region_signal if you may query more than one region.

}Today's AI briefing, or any past day's: top stories with their sources and corroboration labels, emerging signals, new entrants, and regulation updates. Drawn from Hacker News, Reddit, Bluesky, arXiv, Hugging Face, lab blogs, tech press in the US, Europe and East Asia, and legislative sources. A curated once-daily synthesis — for raw item-level updates since your last check, use get_new_since instead. Pass a date (YYYY-MM-DD) for a past day; set top_stories_only for a shorter result.
| Argument | Type | Description |
|---|---|---|
| date | string | Optional YYYY-MM-DD for a past briefing (any date in the archive); omit for the latest briefing. |
| top_stories_only | boolean | Optional. True returns only the top stories with their sources, leaving out signals, new entrants, movers, regional highlights and regulation. Omit for the whole briefing. |

}For one company, model, or person: how much of the claim activity Horizon holds provenance data for is self-reported by that entity versus independently evaluated by someone else. Descriptive counts over the last 30 days — not a score, and not a judgement about whether any claim is true. Answers "is the buzz around X coming from X?".
| Argument | Type | Description |
|---|---|---|
| entity* | string | Entity name, e.g. 'Qwen 3.8' or 'Anthropic'. |

}Incremental poll: raw item-level AI news added since a cursor, oldest→newest, with a nextCursor for your next call — use this for "what's new since I last checked"; for the curated once-daily synthesis use get_daily_briefing. Omit cursor for the latest items plus a cursor to start polling from. Returns titles, links and topics.
| Argument | Type | Description |
|---|---|---|
| limit | number | Max items (default 25, cap 50). |
| cursor | string | Opaque cursor from a previous call's nextCursor. Omit on the first call. |

}The current AI signal for a region (china, korea, japan, or eu) — recent, relevance-scored items on that region's models, labs, and analysis, ranked by momentum. Includes local-language press translated into English. The canonical regional tool; get_china_signal is a preset of this with region "china". Returns titles, sources, and links.
| Argument | Type | Description |
|---|---|---|
| limit | number | Max items (default 15, cap 40). |
| region* | string | Region slug (china, korea, japan, eu). |

}Current AI legislation headlines across the US Congress and federal agencies, US state legislatures, the UK Parliament, and the EU, with each item's legislative stage (proposed / committee / floor action / passed / implementation). State bills are the largest share by far; filter with jurisdiction to narrow.
| Argument | Type | Description |

}Semantic 'more like this': given an item id (from get_new_since, search_news, or the feed), returns the most similar recent items by embedding similarity. Titles, sources, similarity scores, links.
