SDKs

Six languages,
one surface

Every SDK exposes the same nine methods, the same typed errors carrying the API error code, and the same X-API-Key auth. Learn it once, use it everywhere.

JavaScript / TypeScript

npm install @fastvision/sdk

Fetch-based, zero dependencies, full TypeScript types. Works in Node 18+, Bun, Deno and edge runtimes.

Python

pip install fastvision

Sync and async clients on httpx. Context-manager friendly, typed errors, wait_for with timeout.

Go

go get github.com/fastvision-ai/fastvision-go

Idiomatic client with contexts on every call, error types that unwrap the API envelope.

Swift

.package(url: "https://github.com/fastvision-ai/fastvision-swift", from: "0.1.0")

URLSession + async/await. iOS 15+, macOS 12+. Codable models for every resource.

Kotlin

implementation("ai.fastvision:fastvision-kotlin:0.1.0")

OkHttp under the hood, coroutine-first API, works on Android and server-side JVM.

Flutter / Dart

flutter pub add fastvision

Pure Dart on package:http — one client for Flutter mobile, desktop and web.

Consistent by contract

The same nine methods, everywhere

Method casing follows each language's convention (waitFor / wait_for / WaitFor) — the behavior is identical.

  • ocr.image(file, opts)
  • ocr.pdf(file, opts)
  • ocr.document(file, opts)
  • jobs.get(id)
  • jobs.waitFor(id, opts)
  • jobs.delete(id)
  • tts.create({...})
  • tts.voices()
  • tts.download(jobId)
