tZERO

tZERO Technologies is a US financial-technology company building regulated infrastructure for tokenized real-world assets and digital securities. Through its SEC- and FINRA-regulated broker-dealer, Alternative Trading System (tZERO ATS, continuously operating since 2019), special purpose broker-dealer for digital custody, and SEC-registered transfer agent, tZERO covers the full lifecycle: capital formation and token issuance, secondary trading and market data, clearance and settlement, cap-table recordkeeping, corporate actions, dividends and proxy voting. Its developer surface — marketed as tZERO Connect — publishes two public OpenAPI 3.0.3 contracts (an Issuance & Secondary Markets REST API on gateway-web-api.tzero.com and an Institutional transfer-agent / tokenization / custody API on api.t0direct.com) alongside FIX 4.2 / 4.4 specifications for order entry, drop copy and market data.

tZERO publishes 28 APIs on the APIs.io network, including Authorization API, Balance API, Bank Accounts API, and 25 more. Tagged areas include Company, Digital Securities, Tokenization, Capital Markets, and Trading.

The tZERO catalog on APIs.io includes 1 event-driven AsyncAPI specification.

tZERO’s developer surface includes authentication, documentation, API reference, getting-started guide, support, engineering blog, signup flow, and 30 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% 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/tzero: open an issue to ask a question, or submit a pull request to add artifacts.
