Should I bet production on this SDK right now?

Cautiously. The digest carries an explicit caution that it is unofficial, mostly AI-written, and being fixed through experimentation, so pin via `flake.nix`, run the test suite, and expect rough edges.

How does async actually work under the hood?

It is a thin coroutine layer only. The transport stays blocking libcurl, so each offloaded call holds a scheduler slot; fan out before awaiting for concurrency or drive `curl_multi` yourself for non-blocking IO.

How do errors and retries behave?

Errors form a sum type with `ApiError` kinds such as BadRequest, Authentication, RateLimited, and ResponseValidation naming the field path. Defaults retry twice after the first attempt honoring retry-after headers.

Which contract does it track for parity?

The Rust SDK, which mirrors the Python SDK 0.6.0 contract and OpenAPI 0.2.0. Treat noul as a double probability rather than a boolean, and look answers up by name or scan the mixed map.

What compiler and build toolchain does the SDK require?

A C++23 compiler such as clang, CMake 3.24 or newer, Ninja, libcurl, nlohmann/json, and GoogleTest. All are pinned in flake.nix.

What defaults does the client use for model, base URL, and timeout?

Base URL https://api.typesafe.ai, model jev-latest, and a 10-second timeout per attempt. Constructor values win over environment variables, and whitespace-only environment values are ignored.

How can I try the examples without a live API key?

Examples run against an in-process mock server by default. Set TYPESAFE_LIVE=1 to point the same examples at the live API.

About this project

Unofficial C++23 client for the TypeSafe AI API. It is a hand port of the unofficial Rust SDK and targets the same wire contract (POST /v1/systemone, GET /v1/models). Callers send named questions about some state and read back typed answers. Read AGENTS.md before writing SDK or integration code. Copy from examples/systemone.cpp. C++23 compiler (clang, provided by flake.nix) All of these are pinned in flake.nix. Format C++ sources with clang-format (style is .clang-format):

Highlights

Synchronous blocking client on libcurl with `nlohmann/json`; reads the key via `Client::from_env`.
Returns `std::expected` results with no exceptions; the builder compiles only after `api_key(...)`.
Layers opt-in coroutines over a caller-supplied `Scheduler`, with bundled thread-pool and inline executors.
Retries 408/429/5xx plus connection and timeout errors twice with 0.5s to 5s backoff inside a 30s budget.

Watch out

The author flags it as mostly AI-written and under active fixes; build inside the pinned Nix shell. Copy reviewed against the repository README on 2026-10-04, not from running it.
