lemon.markets
lemon.markets is a Berlin-based, BaFin-licensed investment firm that sells brokerage infrastructure as an API. Its Brokerage API lets fintechs, banks and platforms embed investing — account opening and KYC/identification, securities accounts, order placement and execution, trades, positions, transactions, withdrawals, settlements, corporate actions, income distributions, tax exemption orders (Freistellungsauftrag) and treasury products — without building or licensing a broker-dealer stack themselves. Coverage spans 10,000+ ETFs, ETPs, stocks, bonds and funds, and the platform supports omnibus, fully disclosed and BPO (business process outsourcing) operating models. The REST API is complemented by a webhook/event surface, an Idempotency-Key contract on order placement, and a sandbox environment with published test ISINs. API access is invite-only.
lemon.markets publishes 17 APIs on the APIs.io network, including Accounts: General API, Accounts: ID+V API, Batch Orders API, and 14 more. Tagged areas include Company, Fintech, Brokerage, Investing, and Trading.
The lemon.markets catalog on APIs.io includes 1 event-driven AsyncAPI specification.
lemon.markets’ developer surface includes authentication, sandbox, documentation, API reference, getting-started guide, changelog, support, and 25 more developer resources.
