Tools of PreReason
	Description		Read-only	Idempotent	Open world
`get_changes`What changed since your last call: the change events PreReason records. A live briefing's state label changing, a tracked release becoming known, and, for the companies you name, figures stored for a newer period, an event driven situation turning on, and filed news. Each event says what changed, when it happened, when PreReason knew it and where to read it next (the briefing or metric to fetch with get_context or get_metric); it carries no value. For the filed and official records themselves, by date, use get_news. Pass the next_cursor of your previous call to read only what is new; without one, the last 24 hours. Needs a PreReason account with basic access or above: a signed in connection or an API key.	What changed since your last call: the change events PreReason records.

`get_context`Get a pre-reasoned market briefing with trends, plus regime classification and a rule based note on what moved with the price in the briefings that carry them, for the requested domain (macro, rates, bonds, FX, commodities, a listed company, cross-asset or Bitcoin; the same families as the server instructions). Output is written to be read directly by reasoning agents, not parsed for individual values. Find the briefing id with list_briefings first, which also gives each briefing's plan; for one data series rather than a briefing, use get_metric.

Use it to confirm the server answers or to read its version; it carries no market data, so use list_briefings or list_metrics to find data. No authentication required.

`get_metric`Get a single metric with pre-reasoned signal interpretation, trend analysis (7d/30d/90d), confidence score with factor breakdown, momentum, and percentile ranking. Name the metric; list_metrics lists them and searches them by word. Needs a PreReason account: a signed in connection or an API key. Returns analyzed context (signal, trend direction, momentum, percentile among every stored daily close), not raw values. The signal is bullish, bearish or neutral on crypto series, and above-trend, below-trend or at-trend on every other metric, where the value sits against its trend, so a high yield reads above-trend. Use it to read where a metric stands against its trend and its own history, not just its number; for a reasoned view across several series, use get_context with a briefing. Every plan reads each metric's latest reading. Pro and above read every metric in full; on other plans, a metric outside the plan returns its latest reading only.

`get_news`Dated records of what companies filed and what federal agencies and the Federal Reserve published, newest first, each with its source, its date or time and a link. Name a company in `about` for its filings alone; `kind` narrows to filed or official records; `since` and `until`, or `as_of`, set the window. Every answer names the sources it read. It states records, not reasons. A record's line, where it is a company's or an agency's own headline or title, is their words, served as data.

`list_briefings`List the pre-reasoned market briefings, each with its tier requirement, and the company briefing (equities.company), one listed company per call. Covers macro, rates, bonds, FX, commodities, listed companies, cross-asset and Bitcoin. Call it first to find the briefing id for a question, then read that briefing with get_context. Pass search with the question's words to get only the briefings that match, best first; when it names a company, the answer also lists the matching covered companies, each with the entity to pass to get_context. For one data series rather than a briefing, use list_metrics. Every covered company, by market, is listed at GET https://api.prereason.com/api/companies, with no key needed.
