What is an API key and why do some AgentStructure apps need one?

You want your personal AI to know about a new SEC filing or a new government contract, but it cannot see inside your accounts. An API key is the small piece that lets it ask the right app, and only that app, for you.

An API key is a private password that lets your AI assistant ask an AgentStructure app for your alerts.

Key takeaways

The short version.

  • An API key is a private code that tells an app your AI assistant is allowed to ask for your information.
  • Without a key, your assistant has no way to know which watchlist, résumé match or topic is yours.
  • The key and the MCP address both come from the app's connect page, so setup takes a few minutes.
  • Alerts can reach you by text, email or your favorite AI, and the key only matters for the AI route.
  • Keep the key private, and generate a new one if you ever think it has been shared.

Who it is for

Why does connecting my AI to an app feel so confusing?

  • Here is the problem many people hit today.

  • The fix is to let your assistant ask a live source directly.

  • This is for anyone who follows markets, filings, contracts, jobs or other fast-moving topics and would rather have the alert come to them.

Here is the problem many people hit today. You have a personal AI that is good at explaining things, but it only knows what you tell it in the moment. It does not know that a company on your watchlist just filed an 8-K, that a federal solicitation matching your business just opened, or that a job that fits your résumé was posted this morning. So you end up checking websites by hand, and the news you cared about is already hours old.

The fix is to let your assistant ask a live source directly. But then you run into words like API key, MCP address and connector, and it is easy to give up. This article explains those words in plain language and shows how a few AgentStructure apps use them.

This is for anyone who follows markets, filings, contracts, jobs or other fast-moving topics and would rather have the alert come to them. You do not need to write code. You only need to copy two things from a page and paste them into your assistant.

Use cases

3 ways people use What is an API key and why do some apps need one?.

  1. SEC filings

    1. A watchlist that your AI can actually check

    Say you hold shares in a few companies and you want to know when one of them files something important. SECstocksignals.com sends real-time alerts when breaking SEC filings hit companies on your watchlist, with analysis of what changed and what it could mean for your holding.

    The API key is what lets your assistant ask about your watchlist and not a stranger's. After you connect it, you can ask whether anything is new today. The alert tells you a filing landed, for example a new 8-K about a change of chief financial officer, and links to the original. You then read the source and decide what to do. The app reports. It does not give investment advice.

  2. Contract matches

    2. Contracts texted to you before the deadline

    Picture a small construction business in Virginia that wins work from government solicitations. GovContracts.Money identifies new opportunities relevant to your business and texts them to you as soon as they appear.

    Texting needs no key at all. The key matters when you also want to say to your AI, find construction contracts in Virginia, and get open matches ranked by fit with deadlines and official SAM.gov links. The key tells the app which account is asking. Your next step is to open the SAM.gov link and check the deadline.

  3. Résumé matching

    3. Job matches that start from your résumé

    Suppose you are looking for an operations role and do not want to refresh job boards all day. RoleRank.me compares new openings with your résumé and experience and texts you the most relevant ones when they are posted.

    Your résumé is personal, so the app has to know the request really comes from you. That is another job for the API key. Once your assistant is connected, you can ask whether any new jobs fit your résumé and hear why a role fits and what it may be missing. Then you open the apply link, or skip it.

How to

How do I get and use an API key?

  1. Step 1

    Open the app's site, for example secstocksignals.com, govcontracts.money or rolerank.me, and sign in.

  2. Step 2

    Pick what you want to watch, such as a watchlist, a search or your résumé.

  3. Step 3

    Go to the app's connect page and copy the API key and the MCP address.

  4. Step 4

    Paste both into your AI assistant's connection settings. A personal AI such as Instinct or Muse is a natural fit.

  5. Step 5

    Ask a test question, like whether anything is new today, to confirm it works.

Treat the key like a password: do not post it or share it. If you think someone else has seen it, create a new one from the connect page. The apps are free during the beta, and alerts can also arrive by text or email without any key.

FAQ

Frequently asked questions.

What is an API key in simple terms?

It is a private code that proves a request is coming from you. When your AI asks an app for your alerts, the key tells the app which account to answer.

What is the MCP address?

It is the address your AI assistant connects to so it can talk to the app. You get it on the app's connect page, next to your API key.

Do I need a key to get text or email alerts?

No. The key is for connecting your AI assistant. Text and email alerts reach you without it.

Do all AgentStructure apps need a key?

The apps with a connect page, such as SECstocksignals.com, GovContracts.Money and RoleRank.me, use a key and an MCP address. Free trackers like FedRegTracker.com, ClinicalTracker.org, LocalEventsTracker.com and Realty.Bingo have their own sites, where their MCP connection is described.

Can an app use my key to trade or act for me?

No. The apps report information to you and your assistant. They do not give investment, medical or legal advice, and they never trade or act on their own.
