How do I mix Choice, Score, and Noul in one call?

Use plain or pointer structs; values are copied into Questions while pointers reflect later edits. Keys you choose are reused for the matching answers, and Choices, Scores, and Nouls filter by type.

Do I have to hand-write the JSON type field myself?

No. The SDK adds the JSON type automatically, and state plus instructions accept String, Object, or Array. Structured instructions can bundle the question with supporting data like policy text.

Which wins between defaults, environment, and options?

Defaults, then environment, then explicit options win. Set key, model, base URL, timeout, retries, or custom HTTP client per client, or WithRequestModel for one evaluation.

How do retries and API errors surface in Go code?

Non-2xx responses return ApiError with status, body, and detail for errors.As checks. Transport errors, 429, and 5xx retry per WithMaxRetries, honoring numeric Retry-After.

Is typesafe-go an official TypeSafe SDK, and how is it installed?

No. The README calls it an independent community project not affiliated with TypeSafe AI, installed with go get github.com/yoneyy/typesafe-go. NewClient reads TYPESAFE_API_KEY from the environment, so export your key before the first call.

What are the caps on Choice options and Score levels?

Choice accepts an Object of up to 255 option descriptions, Score takes an Array of 2 to 10 level descriptions, and Noul's true/false object is optional. The README points to the TypeSafe API reference for the exact request schema and criteria limits.

How do I list the models available to my account?

Call client.Models with a context; the returned list carries each model's Name and ReleaseDate. For one evaluation you can override the client default by passing WithRequestModel to SystemOne instead.

About this project

An independent Go SDK for TypeSafe AI. Send text or structured data to System One, ask typed questions with Jev, and work with typed answers in Go. The package also supports model discovery. This is a community project and is not affiliated with TypeSafe AI. Set your API key before running the example. NewClient reads it from the environment automatically. Noul returns a value from 0 to 1, representing the probability of a “yes” answer. The returned model ID and token usage are available on the response.
