The steps

  1. Compare the options

  2. Open the listing and subscribe to the free plan

    Every listing links straight to the marketplace page. AI lawyer — online legal advice & attorney consultation is the most subscribed one in this category, which makes it a safe first stop. The Basic plan costs $0 and asks for no card.

  3. Copy your API key

    The key appears the moment the subscription is created. It goes in a request header — never in front-end code or a public repository.

  4. Make the first call and check the quota

    The marketplace playground runs a real request in the browser before you write any code. Once it answers, watch the monthly quota: the free tier is generous but not unlimited, and every Legal listing publishes its own limit.
