Create an Anthropic API key (Claude)

The platform works on a BYOK (Bring Your Own Key) basis: you provide your own Anthropic key and AI costs are billed to you directly by Anthropic, with no markup. Here is how to get that key in a few minutes.

Steps

  1. Go to console.anthropic.com and create an account (or sign in).
  2. Add credit in Billing > Plans & Billing. Anthropic works on prepayment: without credit, keys return nothing. An initial top-up of 5 to 20 € is more than enough to get started.
  3. Open the API Keys section from the left-hand menu.
  4. Click Create Key, give it a descriptive name (for example "outreach"), then confirm.
  5. Copy the displayed key immediately: it starts with sk-ant- and is only shown once.

Connect the key in the app

  1. In the platform, open Settings > AI Key.
  2. Select the Anthropic (Claude) provider.
  3. Paste the sk-ant-... key, then save. The key is encrypted and attached to your workspace.

About credit and cost

  • You only pay for what you use, on a usage basis (per thousands of tokens), directly to Anthropic.
  • Generating an outreach email usually costs a few cents. Keep an eye on your balance in the console to avoid an interruption.
  • You can set a monthly spending limit in Anthropic's billing settings to stay in control.
