Quiver Premium or the Quiver API?
Quiver comes in two forms: a website you log into, and a data feed you plug into your own tools. They cover much of the same ground, but they're built for different people doing different things. Here's the plain-English difference — and how to tell which one fits what you're trying to do.
- Premium You want to look at the data and act on it — charts, rankings, strategies, alerts. No setup, nothing to build.
- API You want to get the data into something of your own — a spreadsheet, a script, an app, a model you're building.
- MCP Not a third product. It's a way to use an API subscription inside an AI assistant like Claude, so you can ask questions in plain English instead of writing code.
Side by side
| Quiver Premiumthe website | Quiver APIthe data feed | |
|---|---|---|
| What it is | A subscription to quiverquant.com — dashboards, rankings, and tools we've built for you | Direct access to the same underlying data, delivered as raw records to software you control |
| How you use it | Log in and browse, in a normal web browser | Your code, spreadsheet, or AI assistant requests the data and you decide what to do with it |
| Do I need to code? | No — everything is point-and-click | Usually — or use MCP to skip the code (see below) |
| Analysis included? | Yes — backtested strategies, scores, and rankings are done for you | No — you get the numbers and do your own analysis |
| Where you sign up | quiverquant.com/pricing | api.quiverquant.com |
| Best for | Investors who want research and signals they can act on today | Developers, quants, analysts, and anyone building something on top of the data |
These are two separate subscriptions, billed separately. Premium doesn't include an API key, and an API key doesn't unlock the Premium features on the website. Plenty of people have both.
The data feed
An API is a way for one piece of software to ask another for information. In practice: your program asks Quiver for "every insider purchase filed in the last month," and gets back a clean list of records — no web pages, no charts, just the data. What you do with it is entirely up to you.
If Premium is a meal at a restaurant, the API is the groceries delivered to your kitchen. Same ingredients, and far more control — if you want to cook.
Programmatic access to Quiver's datasets, including congressional trades and stock holdings, insider transactions, politician net worth, government contracts, corporate lobbying, corporate donors, patents, executive compensation, hedge fund activity, top shareholders, off-exchange trading, app ratings, and the Quiver newsfeed.
Datasets are grouped into tiers, and plans (Hobbyist and Trader) differ in which tiers they include — so what you pay depends on which data you actually need. Access includes the Quiver MCP server at no extra cost.
It does not include the website's Premium features. Strategies, copytrading, the screener, and the backtesters live on quiverquant.com.
- Anyone testing a strategy properly. You want to know whether insider buying actually beat the market over five years — with real historical data and your own rules. See a worked example.
- Developers building a product. An app, a dashboard, a newsletter, or a bot that needs fresh Quiver data flowing in on its own schedule.
- Analysts who work in Python, R, or Excel. You already have a model. You want these numbers inside it, not in a browser tab.
- Researchers and journalists working at scale. Not one lookup but thousands — every filing across every company over a decade, ready to analyze.
Your API subscription, inside an AI chat
MCP stands for Model Context Protocol — a standard way for AI assistants to connect to outside sources of data. Quiver runs one of these connections, so an assistant like Claude can pull live Quiver data in the middle of a conversation instead of guessing or working from stale training data.
The important part: MCP isn't a separate subscription. It uses the same Quiver API key you'd use in code, so any API plan already includes it. Setup is a one-time copy-and-paste into a settings file — the MCP setup guide walks through it in four steps.
- "Which senators traded defense stocks in the last 30 days?"
- "Show me recent insider purchases at NVDA and how big they were."
- "Which companies increased their lobbying spend the most last quarter?"
You ask in plain English; the assistant fetches the real records and answers from them. No endpoints, no code.
- People who want API-grade answers without programming. The data is as raw and complete as the API, but the interface is a conversation.
- Analysts with one-off questions. Not every question is worth writing a script for. Ask it, get the answer, move on.
- Anyone building AI research workflows. Turn an assistant into a research terminal that reads live Quiver data. Watch how.

Common questions
No. They're separate subscriptions with separate signups and separate billing. If you want both, you subscribe to both.
No. MCP authenticates with your existing Quiver API key, so it's included with any API plan. There's nothing separate to buy.
They draw on the same datasets. The difference is depth and format: the API hands you complete raw records to work with, while the website shows the parts most useful for research, already summarized and charted.
Not necessarily — that's exactly what MCP is for. Once connected, you ask questions in plain English and an AI assistant does the fetching. It's the only part of the API that needs no programming at all.
Yes. The website's live dataset dashboards are free to browse without a subscription, so you can see the data before deciding.
