Stock news API: the headlines on a ticker over a date range, as rows your agent can read

What’s the best way to ask ChatGPT?

set up treg — https://treg.to/llms.txt

Using treg, get the news on NVDA from the last seven days, drop anything that is not about the company itself, and give me the five stories that matter with one line each and the source link.

Why this prompt works

Why go through treg.to

One provider, free for 50 calls a day on treg.to's key

Finnhub answers this job, served on treg.to's own free-tier key with an allowance of 50 calls a day per team. Past the allowance the call is refused with a hint to connect your own key, and on your own key it is never metered.

treg call finnhub.company.news --query symbol=AAPL --query from=2026-08-10 --query to=2026-08-15

Every endpoint on this shelf is listed on the Stock Market Data shelf.

What people actually struggle with

Stock news threads are half vendors: about 30 of the ~190 Reddit and X posts in August 2026 were news APIs pitching themselves, two of them in five subreddits each with the same 'I polled the free ones and then found this' arc. These four are people building on their own.

The first thing the model admits is that it cannot see the market

“Then on the second day ChatGPT told me, "Uh... I can't actually see live stock prices."” r/ClaudeAI, 432 points

What this page can do about it: That poster spent eight months wiring data in by hand, and Finnhub's news was one of the feeds. One setup line gives the agent the same call, with the price of every other tool shown before it spends anything.

Free tiers are for trying, not for the backtest

“Their free tiers don't provide enough history for a proper multi-year backtest.” r/algotrading, 13 points

What this page can do about it: True of this one as well. The allowance settles whether the feed fits; a multi-year pull is your own key and Finnhub's plan, and the page says so instead of hiding the cliff behind a free badge.

Nobody knows which news feed is actually current

“I have seen some reviews of Polygon.io saying their news feed is outdated by months” r/algotrading, 17 points

What this page can do about it: No comparison table can answer that honestly for your tickers. The cheap test is the point of the allowance: pull last week on five symbols today and read the timestamps yourself.

The tagging puts stories under the wrong symbol

“company news sometimes gets tagged with the wrong symbol because I'm trusting Finnhub's endpoint scoping instead of double-checking it.” X

What this page can do about it: A known property of the feed, so make the agent do the double-checking: keep the headline and summary, drop what is not about the company, and carry the URL for anything it flags as material.

What actually differs

The free allowance is a trial, not a plan.

treg.to serves Finnhub's company news on its own free-tier key at 50 calls a day per team; past that the call is refused with a hint to connect your own key, and on your own key nothing is metered. Finnhub's free tier carries its own rate limit and, per Finnhub's own docs, this endpoint covers North American companies, so a UK or Indian ticker is not this tool's job.

Symbol tagging is Finnhub's, and it is generous.

A story about the chip sector arrives under every chip ticker, and at least one builder in the research shipped wrong-symbol rows by trusting the scoping. Ask the agent to check that the headline is about the company, and to keep the article URL so a human can verify the ones that count.

This is headlines and summaries, delivered after publication, not a real-time wire.

The forum wants full text from the paywalled sources and a sentiment number; no free feed gives either, and this page will not pretend to. What the rows are good for is the morning brief, the earnings-week watch, and a pre-trade sanity check on what happened overnight.

What is a stock news API?

A stock news API returns the news articles tagged to a company as data, by ticker and date range, so a program can read them instead of a person scrolling a feed. Each row is a headline, the source, a summary, a timestamp and the article's URL. It is not the article itself, which stays on the publisher's site, and it is not a verdict on whether the news is good; providers that sell sentiment scores layer that on top, and this endpoint does not.

Before you start

Is the stock news API free?

50 calls a day per team on treg.to's own Finnhub key, free, which is enough to try it and to run a daily brief on a handful of tickers. Beyond that, register your own Finnhub key and the calls are never metered by treg.to.

Does it include sentiment?

No. The rows are headline, source, summary, time and URL. Sentiment is the agent's reading, or a separate provider's product; this endpoint returns the news, not a score on it.

Do I get the full article?

No. You get the headline, a summary and the link. Full text from paywalled outlets is not something any news API on the free side hands out, and the link is there so a person can read the ones that matter.

Can I build a trading bot on it?

Not on the free allowance, which is a daily trial, and not as a real-time signal: the feed is post-publication. On your own key a polling bot is between you and Finnhub's limits; the news is an input for the agent to reason over, not a trigger.
