How does this compare with the official Python and JS SDKs?

Retry defaults and wire behavior intentionally match them so a working integration ports without re-tuning, plus Go interceptors, typed Question structs, and analyzers. It is community-maintained, not vendor-supported.

Why does my Noul answer have no confidence?

By design: a Noul carries a single 0-1 probability, and distance from 0.5 already encodes uncertainty. The Confidence accessor reports absence for Nouls instead of returning a misleading zero.

What happens when I ask three questions at once?

Every question sees the same state and evaluates in parallel, so asking three costs barely more than asking one. The README advises packing every question about a state into a single call.

How do I handle rate limits without hammering the API?

Catch RateLimitError and sleep for RetryAfter, which is zero when the server sends no preference. Retries cover 408, 429, 5xx, and 529 with backoff and jitter inside a 30-second budget; 422 never retries.

What are the typesafe-go retry defaults?

Two retries, 500ms backoff doubling to a 5s ceiling, plus or minus 25% jitter, within a 30s overall budget, matching the official Python and JavaScript SDKs. 408, 429, 5xx, and 529 are retried; 422 never is.

What Go version and dependencies does typesafe-go need?

Go 1.23 or newer and zero dependencies. It is Apache-2.0 licensed and community-maintained, not affiliated with TypeSafe.

How do typesafe-go errors expose the request id?

Every documented failure unwraps to an APIError, and APIError.RequestID carries the x-typesafe-request-id header, worth quoting in a support ticket. Credentials are scrubbed from every error string.

About this project

A community-maintained Go SDK for the TypeSafe System One API and its model, Jev. Send one state and a map of typed questions. Get one typed answer per question, with calibrated probabilities your code can branch on. Real output from the live API: Every question sees the same state and is evaluated in parallel, so asking three costs barely more than asking one. Pack every question about a given state into a single call. Full guidance on wording, catch-all options and thresholds in DECISIONGUIDE.md.

Highlights

Noul returns a bare probability with no confidence field; near 0.5 is the model saying it does not know.
Retries match the official SDKs and send byte-identical bodies; 422 validation errors are never retried.
Typed errors unwrap to APIError with request IDs, and credentials are scrubbed from error strings.
Ships a user manual, decision guide, wire contract, ten CI-replayed examples, and migration notes.
