hsl.fi
HSL (Helsinki Region Transport) publishes public transport data and offers APIs related to ticketing and commuter-benefit integrations. Its services cover journey and realtime transit data, Bluetooth beacon data, and sales interfaces for HSL tickets and benefits.
hsl.fi exposes four developer-facing HTTP surfaces on its own domains: public Beacon and GTFS-RT feeds, plus authenticated OpenMaaS and Partner ticketing APIs; no GraphQL, MCP, or CLI surfaces were found on hsl.fi subdomains.

Sign up or log in at the HSL OpenMaaS Developer Portal to manage your organization's API keys and payment details. HSL states that using the OpenMaaS API also requires a contract with HSL; the portal says to start the contract process with HSL and provides contact details on the portal page.
Create or log in to your company account in the HSL Business Portal as described on the Partner API page. In the company information tab, use the button at the bottom of the page to create the interface key needed for the Partner API integration. HSL notes the API is being piloted with selected clients; contact corporate customer service via the Partner API page if you want to try it.
