Taurus

Taurus SA (Taurus HQ) is a Geneva-based digital asset infrastructure provider for banks and financial institutions. Its platform spans four institutional products exposed through APIs: Taurus-PROTECT (bank-grade custody of cryptocurrencies, digital assets, and private keys secured in FIPS 140-2 Level 3 HSMs), Taurus-CAPITAL (issuance and lifecycle management of tokenized securities and digital assets), Taurus-EXPLORER (blockchain node and indexing services across dozens of protocols), and Taurus-PRIME (institutional trading connectivity with deep liquidity via REST and FIX). The Taurus-PROTECT REST API (versioned /api/rest/v1/) uses bearer plus HMAC request signing, cursor-based pagination, and governance rules enforced by digital signatures, with first-party Java, Go, Python, and TypeScript SDKs, OIDC/SAML SSO, and SCIM provisioning.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime (on an ambiguous tag, where no other regime matched), 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/taurus: open an issue to ask a question, or submit a pull request to add artifacts.
