Clearstream Banking S.A. is the Deutsche Borse Group post-trade infrastructure business, providing settlement, custody, collateral management and investment-fund order routing for international securities. Its programmable surface has two layers. The incumbent layer is regulated post-trade messaging: clients connect through ClearstreamXact (Xact Web Portal, Xact File Transfer over SWIFTNet FileAct, and Xact via SWIFT FIN), CASCADE via SWIFT and MQ, Vestima for fund order routing and CmaX for triparty collateral, exchanging ISO 15022 MT and ISO 20022 MX messages whose specifications Clearstream publishes to SWIFT MyStandards, with migration to ISO 20022 driven by the SWIFT CBPR+ programme. The newer layer is a genuine REST platform at api.clearstream.com, running an OAuth 2.0 password grant hardened by mandatory mutual TLS, whose first published API is SCIM 2.0 user management for the Xact Web Portal; a free synthetic Playground API and a CmaX collateral surface are live alongside it. The OpenAPI definitions are published into the Deutsche Borse Digital Business Platform catalogue, which requires registration.
Clearstream publishes 8 APIs on the APIs.io network. Tagged areas include API Platform, Capital Markets, Collateral Management, Custody, and Financial-Services.
The Clearstream catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
Clearstream’s developer surface includes developer portal, documentation, getting-started guide, support, signup flow, engineering blog, authentication, and 24 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Securities & Market Data 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.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
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/clearstream: open an issue to ask a question, or submit a pull request to add artifacts.
