Company financials checked against historical prices, in one pass
One sentence in, and a companion has been through the Polygon company financials, put them where you can read them, and marked the ones it was not sure about.
Open the company financial. Check it against something else. Write the change. Move to the next one. That is the Polygon afternoon nobody can hand off, and a companion does the whole pass and gives you back the batch, with nothing changed until you say so.
What it can do is exactly what Polygon exposes to an account you authorise and nothing beyond it: 3 operations, 3 reads and no writes. In practice that means it can get a stock price, get historical prices and get company financials, and work across the company financials, historical prices and stock prices.
The Polygon API stops at Polygon. A companion does not. The same run opens the customer's website, the supplier portal, the internal tool somebody built in 2019, because it is working the browser you are already signed into rather than calling in from outside it.
Can it get stock price on its own?
All 3 operations read.
Your account, not a guess at it: a companion can get a stock price, get historical prices and get company financials, and the full list below is the whole list, with nothing inferred from Polygon's documentation.
The company financials are what most of this inventory is about, alongside the historical prices. A companion can hold all 3 of these operations and forty open tabs in the same pass, which is how an afternoon of Polygon admin becomes a queue you review.
- Get Stock Price
- Get Historical Prices
- Get Company Financials
It can get stock price. Can it act on what it finds?
Through the screens you already use.
Polygon exposes no write operation to a connected account, so a companion drives Polygon in the session you are already signed into instead, filling the same forms you would to move a company financial, and anything consequential stops for an approval card before it happens.
That is the ordinary case rather than the exception. Most of what a company financial in Polygon touches has no API pointed at it, and a companion is useful precisely because it does not need one.
Can it get stock price every morning by itself?
Yes.
Saved as a routine, the Polygon company financials pass runs at the hour you pick: the Monday sweep, the overnight refresh, the Friday check. Keep Awake holds the machine awake for the length of a run, so a scheduled pass finishes with the lid closed.
The product and engineering playbook catalogues the other recurring shapes of the site work, the Polygon company financials sweep among them, and finished runs are published at real runs.
