How is this different from a thin generated Go wrapper?

This one emphasizes strict validation, key masking in six spellings, no bearer forwarding on redirects, clamped retry waits, and a large pooled transport; pick it when those service-hardening details matter.

What happens when the API returns a degraded or truncated body?

It returns a validation error naming the missing field instead of decoding to a confident zero, so a truncated body never reaches branching logic as a false negative.

How do I classify rate limits versus auth failures in code?

Use errors.Is against sentinels like ErrRateLimit or ErrAuthentication, then errors.As for APIError, ConnectionError, or ResponseValidationError detail with request id for support reports.

Do I need a client pool, and how do per-request overrides work?

Create one client with jev.New and share it; it is safe for concurrent use, pools connections, and per-call UsingModel, UsingTimeout, UsingRetry, and UsingHeader overrides apply to one request only.

How do I install it and what Go version does it need?

Run go get github.com/KKloudTarus/taurus-jev-sdk-go. It needs Go 1.22 or newer, has zero dependencies outside the standard library, and imports under the package identifier jev.

Why does it ship its own connection pool?

It builds an http.Transport with 128 idle connections per host against the stdlib default of two. Measured against a 20 ms RTT upstream at 200 concurrent calls, the default gave 1593 rps and a p50 of 106 ms versus 3509 rps and 36.6 ms.

How does a degraded response fail safely?

A field the API documents as required is enforced. A response omitting noul returns a ResponseValidationError naming the field rather than decoding to 0.0, which a plain float would read as a maximally confident no.

About this project

Go client for the TypeSafe AI System One API and its Jev model. Jev answers typed questions about a piece of state and returns calibrated probabilities. It generates no text, so every answer is a value your code can branch on directly. Unofficial client, maintained independently of TypeSafe AI. Zero dependencies outside the standard library.

Languages: Go

Highlights

Requires Go 1.22 or newer with no dependencies outside the standard library, imported as package jev.
Typed Noul, Choice, Score, plus RawQuestion and Answer.Raw so future API primitives do not break services.
Strict validation rejects bodies missing required fields, with sanitized errors that mask the API key.
Jittered retries honoring retry-after with clamps and budget, and a sized connection pool for services.

Watch out

Unofficial client maintained independently of TypeSafe AI, with API-side cardinality limits rather than client-side ones. Copy reviewed against the repository README on 2026-10-04, not from running it.
