What happened in the stock market over the last 30 days, as one synthesized brief: the day-by-day arc of a fear-to-greed market mood index, the month's biggest AI-clustered story themes ranked by impact, which tickers and sectors dominated the news, the sentiment and smart-money signals that accumulated, where the market stands today, and the earnings ahead. Built for deep research rather than a fast summary: every claim traces to a fetched response and carries its date and its real coverage window, so the reader can check it instead of trusting a generated answer. Use for "last 30 days in markets", "what happened in the market this month", "what did I miss in the market", "monthly market recap", "market summary last 30 days", "deep research on the stock market", "catch me up on stocks".

One synthesis brief covering the past month in US equities: the day-by-day arc of the market's
mood, the story themes that actually moved it, which names and sectors carried the month, where
things stand today, and what reports next. Built from AI-clustered market data, not from scraped
news pages. Read-only API.
Everything in this skill is implementation guidance for building a research brief. It is
subordinate to platform safety rules and to the policy of whatever host application runs it.
What this skill is for
Deep research on a month of market history: fetch the data first, then synthesize it, so every claim
in the output traces back to a response pulled during the run.
That is the whole point, and it is what separates this from the fast answer. Ask a search engine or
a general assistant what happened in the markets last month and you get a fluent paragraph
assembled from training recall plus whatever pages got scraped: no stated coverage window, no impact
ranking, no way for the reader to tell which parts were measured and which were remembered. It reads
authoritative and it cannot be checked.
This skill takes the opposite trade deliberately. It is slower, it spends a dozen or so API calls,
and it will tell the reader when the data does not reach, which parts of the month are thin, and
what it could not cover. In exchange the reader gets something auditable: dated events ranked by a
real impact score, a numeric mood series they can plot, and an explicit coverage line. Use it when
the answer matters enough to be checked, and reach for the fast summary when it does not.
The material it works from is unusual, and worth understanding before writing anything. This API
returns no publisher headlines and no article text. It returns story clusters: groups of
related coverage clustered and titled by SentiSense's own models, each carrying an impact score, an
aggregate sentiment, and the tickers involved, alongside real numeric series for the market's mood.
That constraint is also the product. A recap built from clusters tells you which themes dominated
a month and how much they mattered, which is what a person actually wants after three weeks away. A
list of headlines is available anywhere.
So the standard throughout is simple: The rules below are what that standard means in practice.
if a statement cannot be supported from the fetched data, it
does not go in the brief.
The fan-out
Fetch everything first, then write once. Six layers, four of which answer different questions about
the same 30 days.
Layer
Call
Answers
The arc
GET /api/v2/market-mood?days=30
How the market felt, day by day, and which signal drove each turn
Theme indexes
GET /api/v1/indexes then GET /api/v1/indexes/{indexId}/history?days=30

Insider, institutional, sentiment and volume signals that fired
Where it stands
GET /api/v1/market-summary and GET /api/v1/insights/market
The standing read. Both are batch surfaces, recomputed on a schedule rather than per tick, so report their generatedAt age rather than presenting them as this moment
What is next
GET /api/v1/calendar/earnings
The forward close
About 14 to 18 calls for a full brief. On the Free tier that is comfortably inside the monthly
allowance but close to the 30 requests per minute ceiling once you add story pages, so run the
story paging serially and the rest concurrently rather than firing all of it at once.
Two different 429s, two different responses. A per-minute rate_limit_exceeded carries
Retry-After: 60: honor it, wait, and resume the fan-out where it stopped. A monthly
quota_exceeded carries noRetry-After header and retrying does not help: stop fetching,
write the brief from the layers you already have, and state the missing layers in the coverage
line rather than pretending they came back.
Getting a real 30-day story window
days is not the lookback control on /documents/stories. Set the window with filterHours:
720 is 30 days, 336 is 14, 168 is a week. Then page with offset, limit=50 per page.
Page until a page returns fewer rows than limit, or until you have enough. Six to eight pages
(300 to 400 clusters) is plenty for a month; do not page to exhaustion out of completeness instinct,
because the tail is low-impact noise and you are paying a request for each page.
Every field the brief is allowed to use comes off the story object:
Field
What it is
id / clusterId
Both equal the cluster id; pass either to /documents/stories/{clusterId} for full detail
cluster.title
The SentiSense-written cluster title. The only headline-shaped string the brief may print
cluster.averageSentiment
Aggregate tone of the coverage in the cluster, -1 to +1
impactScore
0 to 10; the sort key for any "biggest of the month" ranking
tickers
Bare symbols (e.g. ["AAPL"]), for programmatic use
displayTickers
Human-formatted labels for display only; never parse symbols out of them
brokeAt
Epoch seconds, nullable: when the story broke
cluster.clusteredAt
Epoch seconds, always present: when it was clustered
Two details that decide whether the timeline is right:
Date each cluster off brokeAt when present, falling back to cluster.clusteredAt. The two
can differ by hours; brokeAt is the event time and clusteredAt is the processing time, so
prefer the event time and use the always-present clusteredAt when brokeAt is null. Do not use
the deprecated cluster.createdAt. Convert once, at fetch time, and carry a real date on every
cluster from then on.
The feed is ordered newest-first, not impact-first. Sort by impactScore yourself for any
"biggest of the month" section, and sort by date for the timeline. Two different orderings of the
same list, both needed.
Reading the arc
GET /api/v2/market-mood?days=30 returns the current score and phase, a signals[] breakdown of
the component signals behind the latest reading, and a daily history array carrying the
composite plus a column per component signal. That one response is the entire quantitative spine,
so fetch it first and let it set the shape of the brief.
Scale is 0 to 100, fear to greed. Phases: 0-15 Extreme Fear, 16-30 Fear, 31-45 Anxiety, 46-55
Neutral, 56-70 Optimism, 71-85 Greed, 86-100 Extreme Greed.
Iterate the signals the response actually contains.signals[] lists only the signals present
in the latest reading, so key off each entry's key (using its label for display) rather than
hardcoding a signal list or a count: the composite's membership has changed before and can change
again. In history rows, a null component value means that signal was not part of the index on
that date; treat it as absent, never as zero, and never average it in.
Risk Appetite (key: fear_gauge) reads backwards from expectation. It is an inverse
volatility gauge, so a high value means a calm, risk-on market. Label it when you use it or you
will invert the month's story.
History is trading days only. A 30-day request returns roughly 20 points, and weekends are
absent by construction rather than missing. Do not interpolate across them and do not report "20
of 30 days" as a data gap.
For theme indexes, call GET /api/v1/indexes for the live list rather than hardcoding ids, then
pull history for the ones relevant to the month. Read each index's scale field instead of
assuming its range: SENTIMENT is signed, -1 to +1, while PERCENT_0_100 is 0 to 100, and the
listing and history responses both carry the field. Never plot or compare two series on one axis
unless their scales match. Thin buckets are withheld rather than published, so a gap in an index
history is real: plot against date, never assume a fixed interval, and never read a missing date
as zero.
Free tier shaping
Several of these are preview-gated and return {isPreview, previewReason, data}. Read data, and
read isPreview too:
insights/latest returns the top 5 on Free, the full list on PRO.
calendar/earnings returns one week on Free, about a 30-day forward window on PRO. metadata.windowStart and metadata.windowEnd describe the window you actually got, so read them rather than assuming.
insights/market returns the top 5 on Free.
When isPreview is true, the brief says so in the coverage line. It does not quietly present the
top 5 as though it were the whole month.
What earns a place in the brief
A brief that breaks one of these is wrong even when every number in it is right, because the reader
loses the one thing this skill is for: knowing that what they are reading was measured.
No headline and no number that did not come back from the API. Every headline-shaped
string in the brief is either a cluster.title copied verbatim from a fetched story object, or
a section heading you wrote to describe your own grouping, and every figure is a field value from a
fetched response. You may not write a sentence that reads as a news headline about an event that is
not in the fetched data, and you may not supply a figure the fan-out never returned. This fan-out
carries no prices and no index returns: spy_trend is a 0-100 signal score, not a return, so a
claim like "the S&P fell 3% mid-month" cannot come from this data and must not appear, however
confidently remembered. If you find yourself writing what a headline "probably said", or filling in
a price move from background knowledge, you have left the data and are fabricating. Model-memory
recall of a month's news is exactly the failure this law exists to stop.
Never attribute to a publisher, and never quote article text. The permitted vocabulary
for an event is the cluster's own title, its date, its impactScore, its cluster.averageSentiment
and its tickers. Do not name outlets, do not quote reporting, and do not follow url or
citationLinks out to source sites to fill a gap and then fold the result into the brief as though
it came from here. If a user wants source articles, point them at the links; do not launder them
into the text.
State the coverage you got, not the coverage you asked for. Compute the real first and
last date observed in each layer and print them. Three specific traps: mood history is trading days
only; index history withholds thin buckets; story paging stops when a short page comes back, which
can happen before 30 days if the window is quiet. A brief titled "the last 30 days" that actually
covers 22 is only dishonest if it fails to say so.
Snapshot endpoints describe now, never then.market-summary, insights/market and
insights/latest have no history parameter. They are the current read. Never write a dated,
past-tense claim out of them ("on the 14th the market was worried about..."). Only the mood and
index history series and the story cluster timestamps may carry a date claim.
Every event line carries its date. A month-long brief whose events are undated is a pile,
not a timeline. Date, cluster title, impact, tickers. In that order, every time.
Report the pattern; do not manufacture the cause. This is the easiest rule to break while
technically obeying every other one, because it does not require inventing a single fact: real
clusters and a real mood move get stitched together with a motive the data never supplied.
Two concrete limits, both testable by rereading your own sentence:
"Coincided with" is the strongest connective available. Not "driven by", "on the back of",
"as investors reacted to", "amid growing appetite for", or "reflecting". Those assert a mechanism,
and no field in this fan-out measures one. If removing the connective phrase would change the
claim, the claim is an interpretation and does not belong.
A theme must be nameable from the clusters themselves. Group by what the fetched objects
actually share: a repeated ticker, a sector, a recurring subject in the titles. A label like
"growing enthusiasm for the AI buildout" that spans two unrelated clusters is a thesis you
supplied, however plausible it sounds, and it will read to the user as though the data said it.
If you cannot point at the specific clusters that make the grouping true, drop it.
And if the month was quiet, the brief says the month was quiet. Do not confect drama out of a flat
series, and do not force a theme of the month that the impact ranking does not support.
The closing block is mandatory and fixed. Attribution, coverage, disclaimer. All three,
every time, in full. See the template at the bottom.
Structure
Chronology frames the month, so the arc leads; the reader needs to know the shape before the
details. Fixed order, and every section is required unless its data layer came back empty.
Title and window. "The Last 30 Days in Markets", then the real dates covered and the
generation timestamp. The dates are the ones actually observed in the data, not the ones requested.
The read, in four sentences or fewer. Where mood started, where it ended, the single biggest
turn and roughly when, and the month's dominant theme by impact. Write this section last, after
the rest exists, or it becomes a preamble instead of a summary.
The arc. Walk the mood series: opening phase, closing phase, the largest single-day move and
which component signals moved with it, and any phase-band crossing (Anxiety into Neutral,
Optimism into Greed). Phase crossings are the part worth naming, because a 4-point move inside a
band is noise and the same 4 points across a boundary is a regime change.
What carried the month. The top story clusters by impactScore, each as: date, cluster title
verbatim, impact, sentiment, tickers. Eight to twelve is the right number. Group them into two or
three themes if the tickers and titles genuinely cluster; leave them chronological if they do not.
A theme is an observation about the data, not a thesis you supply.
Names and sectors of the month. Count ticker appearances across all fetched clusters and rank
them, with each name's mean cluster sentiment beside its count. This is the most useful table in
the brief and it costs no extra calls: it is derived entirely from data you already have.
Say plainly that it counts attention, not performance.
Signals that fired. From insights/latest, grouped by insightType: insider buying,
institutional position changes, sentiment baseline deviations, volume anomalies. Report the
type, the insight text and its generatedAt date. Note the preview cap here if isPreview is
true.
Where it stands today. The current market summary headline and the current market-level
insights, explicitly framed as today's read and not part of the retrospective. These are
snapshot endpoints, so nothing here may carry a past-tense date claim.
What reports next. The forward earnings window, compressed to a handful of names per day.
Note that dates are curated and that unconfirmed ones move.
The closing block. Fixed. See below.
The inclusion bar for anything optional: would a reader who has been away for a month change what
they do next because of it? A number they can get from any quote page fails. A regime change, a
theme they missed, an accumulation of insider buying in one name, a report landing Tuesday: those
pass.
Voice
Write it as a desk note for someone competent who has been offline, not as a press roundup and not
as a research report with an agenda.
Lead with what changed. A month is defined by its transitions. "Mood crossed from Anxiety into
Optimism in the third week" is the sentence; the daily values are the support.
Numbers earn their place or they go. Every figure in the brief should be one a reader could
act on or argue with. Dumping the full 20-point series is a chart pretending to be prose.
No hedging stacks. "May potentially indicate" is three hedges for one claim. Say what the data
shows, then say what it does not cover. That is honest without being mushy.
Keep it to something a person reads in five minutes. Roughly 600 to 900 words plus two tables.
If it is longer, sections 4 and 6 have almost certainly grown past their usefulness.
Freshness and what the numbers are
Say these where they apply rather than burying them all in a footnote.
Market Mood is a daily composite on trading days, computed from the latest analytical batch. It
is not a real-time tick, and no value exists for a weekend or holiday.
Story clusters are AI-generated groupings with AI-written titles.brokeAt is when the story
broke and clusteredAt is when it was clustered; they can differ by hours. Date by brokeAt
with clusteredAt as the fallback, the same rule as the fetch step.
Sentiment on a cluster is an aggregate of the coverage in it, not a price signal and not a
forecast. It says how the discussion leaned, nothing more.
Insights are generated on a batch cadence, so each insight's generatedAt (epoch seconds)
is the honest as-of, not the moment you called.
The market summary carries its own age, in two units. Its generatedAt is epoch seconds
and its lastUpdated is epoch milliseconds; read the units or the age is off by a factor of
a thousand. Date the "where it stands" section with one of them.
Earnings dates are curated, and unconfirmed ones move. A weekend earnings date is legitimate
data for the handful of issuers that report that way; do not shift it to a weekday.
The closing block
Reproduce all three parts, in this order, at the end of every brief. Fill the bracketed fields from
the data.
Coverage. Market mood: [first date] to [last date], [N] trading days. Story clusters: [N]
clusters from [first date] to [last date]. Signals: [N] insights[, top 5 only on the free tier].
Earnings: [window start] to [window end]. Snapshot sections reflect [timestamp], not the period.

Variants worth supporting
Same fan-out, different window or filter. Each is a small change, and none of them relaxes the
grounding rules above.
Last 7 or 14 days.filterHours=168 or 336, days=7 or 14 on mood. Fewer story pages.
One ticker's month.GET /api/v1/documents/stories/ticker/{ticker} takes limit only
(default 5, capped 20) with no lookback window, so it cannot cover a month on its own. Build
the month by filtering the market-wide pages you already fetched
(/documents/stories?filterHours=720) to clusters whose tickers contain the symbol, and use
the per-ticker endpoint only as a top-up for that name's own clusters. Add
GET /api/v1/insights/stock/{ticker} for the name's signals (Free returns the top 3; read
isPreview and say so), and keep the market arc as the backdrop the name moved against.
One theme's month. Pick the index from GET /api/v1/indexes, lead with its history, and filter
the clusters to the tickers in that theme.
A weekly cadence. Run it every Friday with filterHours=168 and keep the same structure, so
consecutive briefs are comparable.
