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 7 APIs on the APIs.io network, including bLink API, debiX API, debiX Auth Provider API, and 4 more. Tagged areas include Financial, 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.

Regulatory Posture applies to this provider. Its tags matched the Banking & Open Finance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/six-group: open an issue to ask a question, or submit a pull request to add artifacts.
