# Get an API key

> Sign in to the developer console with your Investorlift account, subscribe to the Free plan, copy the key.

An API key comes from the Investorlift developer console. Sign in with your Investorlift account, the account you use on
the marketplace. If you have none, create one there. Accept the developer agreement once.

Subscribe to the Free plan. The console asks for a card and keeps it on file. The Free plan charges nothing. Copy the
key from **Keys and usage**. The console creates the key with the subscription, so you get a key when you subscribe.

The key starts with `zpka_`. It works on `/v1` and on [the MCP endpoint](/mcp/overview) alike. Every snippet on this
site reads it from `GM_API_KEY`.

<Card title="Open the developer console" icon="key" href="https://console.investorlift.com/pricing">
  Sign in with Investorlift. Subscribe to Free. Copy the key. This takes about two minutes.
</Card>

Then the [Quickstart](/guides/quickstart) makes the first call in five minutes. [Plans and limits](/guides/plans-and-limits)
says what a key can do each minute and each month. On [Your keys](/keys) you copy a key again, roll it or delete it.
