@anvia/jev API reference

Import every public symbol from @anvia/jev. The package has no public subpath exports.

Client and model factory

type JevClientOptions =
  | { apiKey?: string; baseUrl?: string; headers?: Record<string, string>; client?: never }
  | { client: TypeSafeClient; apiKey?: never; baseUrl?: never; headers?: never }

class JevClient implements ModelListingClient {
  constructor(options: JevClientOptions)
  decisionModel(options: JevDecisionModelOptions): JevDecisionModelHandle
  listModels(options?: { abortSignal?: AbortSignal }): Promise<ModelList>
}

type JevDecisionModelOptions = { modelId: JevDecisionModelId }
type JevDecisionModelHandle = DecisionModel<unknown>

The constructor and factory require one options object. The model ID is explicit; there is no factory default. The handle is the Core DecisionModel contract. Its provider is 'jev' and its rawResponse is the original SDK result.

Declared capabilities

Field	Value
questionSupport	choice, score, check: native. multi-label: composed.
mixedQuestions	true
limits	maxChoiceOptions: 255, maxRubricLevels: 10

Model IDs

const JEV_LATEST = 'jev-latest'
type KnownJevDecisionModelId = typeof JEV_LATEST
type JevDecisionModelId = ModelId<KnownJevDecisionModelId>

Known IDs provide autocomplete while other strings remain valid.

Model listing

listModels() returns { data } where each item has id and name set to the SDK model name, plus description and type: 'decision'. Failures throw ModelListingError with provider: 'jev', except a caller abort, which rejects with an AbortError.

Namespace

The jev namespace re-exports the same client, constants, and public types. It has no state of its own.

Core decision API

Question helpers and operations are not exported from this package. Import choice, multiLabel, score, check, decide, decideBatch, the errors, and the types from @anvia/core/decision (also available from @anvia/core). See Typed decisions.
