Four languages, one API, no second-class client

Each client is generated from the same specification and then given an idiomatic surface by hand — iterators in Python, async generators in TypeScript, an errors-last iterator in Go. The parity table below is honest about where a runtime is still behind.

Install and make a first call

install
pip install tradelogx-nexus
python · list vetoed decisions
from nexus import Client

client = Client()  # reads NEXUS_API_KEY

for d in client.decisions.list(verdict="veto", limit=20):
    print(d.symbol, d.conviction, d.vetoed_by)
    print(" ", d.rationale)

Every client reads NEXUS_API_KEY from the environment by default. None of them accept a key as a positional constructor argument, which is the single most common way a credential ends up committed.

Feature parity

Where a client is behind, it says so here rather than in a changelog you would have to go looking for.

Versioning and support

Semantic versioning

Majors are rare and always come with a migration guide and a deprecation period of at least six months. A minor never changes an existing signature.

Pinned response shapes

Clients send the Nexus-Version header they were built against, so upgrading the platform cannot change what your code parses. Upgrading the client is the deliberate act.

All four clients are published under the same permissive licence as the rest of what we open source, and the generator that produces them is public too — the details are on the open-source page.
