# Claim Your API Key & credits

> Claim your account, key, and test credits in one step — self-serve, no approval.

Eager to start building on our ADK? You will need test credits to use in your contracts and for interactions with the T3 Network.

<Info>
  **No approval, no waitlist.** This is fully self-serve. Sign in with your work email and your developer key plus test credits are issued instantly — you do not need to request access or be granted anything first.
</Info>

<Steps>
  <Step title="Sign in and claim">
    Head over to the [claim page](https://www.terminal3.io/claim-page) and sign in with your work email.

    Coming from an event or a campaign? Enter your campaign code to receive additional credits (the amount depends on the campaign).
  </Step>

  <Step title="Copy and store your developer key">
    Once you submit the form, your developer key appears immediately. This is the key the SDK uses to authenticate as you — save it somewhere safe.

    <Warning>
      During the test phase, the key is shown only once and can't be retrieved after you leave the page. Copy it before you navigate away.
    </Warning>

    Your unique T3N ID (`did:t3n`) and test credits are generated and linked to this key automatically.
  </Step>
