Our verdict on lemon.markets Brokerage API

lemon.markets Brokerage API is a cloud-based Brokerage-as-a-Service platform from lemon.markets brokerage GmbH in Berlin. It is designed for banks, asset managers, fintechs and other investment businesses that need infrastructure for customer onboarding, brokerage accounts and securities operations. The API covers digital customer and account onboarding, order submission and management, portfolio positions, balances and asset data. Its stated instrument coverage includes ETFs, stocks and funds, making it relevant to products that combine investing access with account servicing.

Pricing follows a contact-sales model, and access to the Brokerage API is invite-only. Organizations therefore begin by engaging lemon.markets rather than selecting a self-serve public plan. The ready-to-test sandbox can support evaluation of API workflows before production use, while documentation and reference materials provide the technical onboarding path. Support is offered through email and documentation, so teams should plan for an API-centered implementation and direct coordination with the provider.

The platform’s scope extends beyond order entry: custody, settlement, taxation and reporting workflows are included alongside webhook notifications for brokerage events. That breadth can fit mid-market and enterprise teams building a European investment product that needs connected front- and back-office processes. The trade-off is a focused delivery model: deployment is cloud-based, the interface is API-only, and entry is invite-only. Choose lemon.markets when European brokerage account infrastructure and post-trade workflows are central requirements; consider alternatives if you need open public access, self-serve pricing or non-API user interfaces.
