Not affiliated with or endorsed by TypeSafe AI. - [TypeSafeAPI.Client](TypeSafeAPI.Client.md): Connection settings for the TypeSafe API, resolved once and passed around. - Evaluating - [TypeSafeAPI.FanOut](TypeSafeAPI.FanOut.md): Evaluate many states against one question set, concurrently. - [TypeSafeAPI.Models](TypeSafeAPI.Models.md): The models endpoint: `GET /v1/models`. - [TypeSafeAPI.SystemOne](TypeSafeAPI.SystemOne.md): Layer 2 for the evaluation endpoint: typed questions in, typed answers out. - [TypeSafeAPI.SystemOne.Prepared](TypeSafeAPI.SystemOne.Prepared.md): A question set that has been validated, encoded, and had its caller keys recorded, ready to send with any number of states. - Questions - [TypeSafeAPI.Question](TypeSafeAPI.Question.md): The three question types and the functions that validate and encode them. - [TypeSafeAPI.Question.Choice](TypeSafeAPI.Question.Choice.md): Pick one option from a set you define. - [TypeSafeAPI.Question.Noul](TypeSafeAPI.Question.Noul.md): A yes/no judgment. The instructions may be a question ("Does this convey urgency?") or a statement to evaluate ("This message contains unsolicited advertising."); the answer is the probability that the answer is yes, or that the statement holds. - [TypeSafeAPI.Question.Score](TypeSafeAPI.Question.Score.md): Rate the state along an ordered scale you describe in steps. - Answers - [TypeSafeAPI.Answer](TypeSafeAPI.Answer.md): Decodes one wire answer against the question that produced it, and turns any answer into a routing decision. - [TypeSafeAPI.Answer.Choice](TypeSafeAPI.Answer.Choice.md): A decoded Choice answer: which option the model picked, and how sure it was about every option it was offered. - [TypeSafeAPI.Answer.Noul](TypeSafeAPI.Answer.Noul.md): A decoded Noul answer: the model's probability that the answer is yes. - [TypeSafeAPI.Answer.Score](TypeSafeAPI.Answer.Score.md): A decoded Score answer: a point on the scale, plus enough structure to use it without hand-decoding probabilities yourself. - Results and errors - [TypeSafeAPI.Error](TypeSafeAPI.Error.md): The single error value returned by every `{:error, _}` tuple in this library. - [TypeSafeAPI.Model](TypeSafeAPI.Model.md): A model available to the account, as listed by `TypeSafeAPI.models/1`. - [TypeSafeAPI.Result](TypeSafeAPI.Result.md): A fully decoded response: every answer keyed by the caller's own question ids, plus usage and the raw decoded body for anything this layer doesn't expose yet. - [TypeSafeAPI.Usage](TypeSafeAPI.Usage.md): Token counts for one call. - Raw HTTP, retries, telemetry - [TypeSafeAPI.HTTP](TypeSafeAPI.HTTP.md): Layer 1: the raw HTTP client. Maps in, maps out. - [TypeSafeAPI.HTTP.Response](TypeSafeAPI.HTTP.Response.md): A successful raw response: the decoded JSON body plus the metadata the typed layer and support conversations need. - [TypeSafeAPI.Retry](TypeSafeAPI.Retry.md): Retry policy mirroring the official TypeSafe SDKs, implemented as a Req step. - [TypeSafeAPI.Telemetry](TypeSafeAPI.Telemetry.md): Telemetry events emitted by this library, plus a small logger handler. - Testing - [TypeSafeAPI.Test](TypeSafeAPI.Test.md): Stub the TypeSafe API in your tests without fixtures or a network. - Internals - [TypeSafeAPI.Application](TypeSafeAPI.Application.md): Starts the one process this library owns: a `Task.Supervisor` named `TypeSafeAPI.TaskSupervisor`, used by `TypeSafeAPI.FanOut`. - [TypeSafeAPI.JSON.OrderedObject](TypeSafeAPI.JSON.OrderedObject.md): A JSON object that encodes its pairs in the order given. - [TypeSafeAPI.Keys](TypeSafeAPI.Keys.md): Request-side registry of caller-supplied keys, so answers come back under the keys you sent.
