niche_angle_propose

Angles on one story (Pro): up to a few distinct stances a reader could take, each with a hook, the take, and the sources that support it. Pass the session_id from a scan and a story_id from its slate. Nothing is written for you; the angles are starting points.

story_idstring, required

id from niche_session_state.stories[].id

session_idstring, required

lensstring

Optional direction for a regenerated angle set, such as focus on the evidence.

regenerateboolean

Request another set of angles after the selected story's angles are ready. Subject to the account's allowance.

niche_feed_read

Read the latest or a dated briefing for a niche: stories, reporting dates, source links, why each story matters, and new or continuing status. Use a slug from https://nicheangle.com/n or a custom niche's URL, such as founders or ai-leaders. Assistant access requires Pro. This reads an existing briefing without starting a scan. A quiet briefing has status=quiet; no_edition means no briefing is available; unknown_niche means the slug was not found.

read-only

Argument	Type	Description
date	string	Optional edition date, YYYY-MM-DD. Default: the latest edition.
niche*	string	Niche slug, e.g. financial-advisors.

niche_intelligence_query

Ask an analyst-shaped question over a fresh scan of a niche (Pro): 'the biggest developments this week', 'what is emerging', 'where money is moving'. Returns the sourced slate plus a short synthesis when requested. Returns a session_id; poll niche_session_state until cp1_awaiting_story. For synthesis, continue polling with wait_until=synthesis and wait=30 until it arrives or a shortfall is reported.

Argument	Type	Description
lens	string	mainstream covers established reporting, emerging emphasizes newer topics, and investment focuses on funding developments.
count	integer	Requested number of developments, from 3 to 15. The result can contain fewer when reporting is limited.
window	string	Reporting window: 24h, week, month, quarter, or year. Pair with recency_strict for a hard cutoff.
subject*	string	The subject/space to investigate (2-200 chars). Specific is better.
synthesis	string	none returns stories only. narratives adds sourced themes across the stories. patterns adds a summary of broader developments. Default none.
recency_strict	boolean	Exclude reporting outside the requested window. Default false; strict windows can return fewer stories.
source_quality	string

niche_list_sessions

List your recent scans: id, the niche you described, status and timestamps. Use it to find a session_id you no longer have.

read-only

Argument	Type	Description
limit	integer	Max sessions to return (default 25, max 100).
offset	integer	Skip this many sessions before returning, for paging through history. Default 0.
status_filter	string	Optional scan status, such as cp1_awaiting_story, cp2_awaiting_angle, complete, or failed.
niche_contains	string	Optional case-insensitive substring filter on the niche input, to find sessions on a topic (e.g. 'walnut').

niche_session_state

Read the current state of a scan: status, the ranked stories with their sources and source information, and any angles already proposed. Poll this after niche_signal_scan or niche_intelligence_query until the slate is ready.

read-only

Argument	Type	Description
view	string	status returns a short progress summary. full returns the stories and available angles. Default full.
wait	integer	Wait up to 30 seconds for progress, then return the current state. Default 0.
wait_for	string	Alias for wait_until. If both are supplied, wait_until takes precedence.
session_id*	string	session_id from niche_signal_scan.
wait_until	string	With wait, return on change, an actionable checkpoint, or completion of synthesis.
since_status	string	Last status received. With wait and wait_until=change, return when it changes.
include_unpicked	boolean	When true, return the full candidate set even after picks have been made. Default false (sparse: only the picked story / angle come back). Meaningful only with view='full'; ignored in view='status' (the lean envelope never carries the candidate slate).

niche_signal_scan

Scan a niche you describe, right now (Pro). Returns a ranked, sourced slate of the stories people in that field are talking about, with source links, the outlets, and why it matters. For a ready-made briefing use niche_feed_read instead. Assistant access requires Pro. Poll niche_session_state with the returned session_id until status is cp1_awaiting_story; the slate is in `stories`.

Argument	Type	Description
niche*	string	Niche / beat description (2-200 chars). Specific is better.
recency	string	Reporting window: 24h, week, month, quarter, or year. Pair with recency_strict for a hard cutoff.
recency_strict	boolean	Exclude reporting outside the requested window. Default false; strict windows can return fewer stories.
source_quality	string	strict prioritizes well-supported stories; balanced is the default; broad includes less-established reporting. Inspect the returned sources before relying on a claim.
idempotency_key	string	Optional stable key for retries of the same scan, so a retry reuses the original run.
thinking_budget	string	balanced returns a session_id immediately. fast waits briefly for stories and returns them if ready; otherwise poll niche_session_state.
