SIX
SIX operates the financial market infrastructure of Switzerland and Spain, including SIX Swiss Exchange, BME, and Swiss interbank clearing and securities services, alongside SIX Financial Information, one of the largest global market data vendors. It sells real-time, intraday, end-of-day, and historical pricing, reference data, corporate actions, and regulatory/ESG datasets from more than 900 price sources, delivered via the SIX Web API (REST/JSON, GraphQL, WebSocket), the SIX Bulk API, streaming Market Data Feed, SIX Flex and Valordata Feed files, and Snowflake cloud shares. A public developer portal at developer.six-group.com fronts the bLink open banking platform, the debiX debit card API, and a shared Kong-based API catalog with Swiss interbank clearing and settlement APIs. Financial data access is enterprise and sales-gated with MTLS certificate authentication, while several Swiss payment infrastructure APIs are publicly documented with downloadable OpenAPI.
SIX publishes 11 APIs on the APIs.io network, including bLink API, Debi X API, debiX Auth Provider API, and 8 more. Tagged areas include Finance, Market Data, Stocks, Reference Data, and Corporate Actions.
The SIX catalog on APIs.io includes 1 event-driven AsyncAPI specification.
SIX’s developer surface includes developer portal, documentation, engineering blog, support, authentication, sandbox, changelog, and 28 more developer resources.
