Free data, no paid API, your electricity

Every one of the 36 sources this terminal reads is a public publisher queried directly, and all of them answer without a credential. No aggregator sits in the middle, so there is no per-call price and no plan to exceed.

SEC endpoints require a declared User-Agent under the fair-access policy. That is a header the server sets, not a key you supply, and it costs nothing.

What free does cost you is reliability. These services throttle: SEC EDGAR enforces fair-access limits, OpenSky limits anonymous polling, GitHub caps unauthenticated requests. When a fetch is refused, the screen says so and names the source. That is the real price of a keyless architecture, and it is paid in occasional unavailability rather than in money.

The plain-English reading under a screen's figures is computed in your browser from the data already on it. There is no model, no API key, and no request — so there is no per-use price, no plan to exceed, and no meter running while you read.

This used to be an AI overview billed per generation, and the arithmetic for it filled this section. It was removed rather than made cheaper. What replaced it is deterministic: the same figures produce the same sentences every time, which a model cannot promise at any price.

The honest answer is that nobody here has measured it. This product does not read power draw and cannot tell you what it costs to run on your machine, and any figure printed here would be a guess dressed as a measurement.

What can be said is how to work it out. Measure the machine's draw at the wall while the server is running, then:

Two things affect the watts. It is one Python process, and it is idle whenever nobody is looking at a screen — but it does refresh cached data in the background while it runs, so it is not free simply because the browser is closed. If cost matters, stop the server when you are not using it; there is nothing to keep warm and startup is quick.

If the machine is one you were leaving on anyway, the marginal cost is smaller still. This page is not going to put a number on that either.

Time. Setting it up, learning six mnemonics, and reading a screen carefully enough to know what it is not telling you. That is the real cost of a tool with no subscription, no support desk and no account manager, and it is worth saying plainly on the page where a price would otherwise be.
