@spekoai/sdk

Official TypeScript SDK for Speko — one API, every voice provider.

Speko is a voice AI gateway that benchmarks every STT, LLM, and TTS provider across languages, then routes each request to the best provider in real time. Failover is handled. You write one integration; Speko picks the right provider for every call.

Installation

npm install @spekoai/sdk
# or
pnpm add @spekoai/sdk

Quickstart

import { Speko } from '@spekoai/sdk';
import { readFile } from 'node:fs/promises';

const speko = new Speko({ apiKey: process.env.SPEKO_API_KEY });

// Transcribe — best STT provider auto-routed for your language
const audio = await readFile('./call.wav');
const { text, provider, confidence } = await speko.transcribe(audio, {
  language: 'es-MX',
  region: 'us-east4', // optional — rank streaming providers in this region
});

// Synthesize — best TTS provider auto-routed
const speech = await speko.synthesize('Hello world', {
  language: 'en',
});

// Complete — best LLM provider auto-routed
const { text: reply } = await speko.complete({
  messages: [{ role: 'user', content: 'Hi!' }],
  intent: { language: 'en' },
});

// Streaming variants are also available:
// speko.transcribeStream(...), speko.synthesizeStream(...), speko.completeStream(...)

The client accepts baseURL as an alias for baseUrl — e.g. new Speko({ apiKey, baseURL: process.env.SPEKO_BASE_URL }). If both are set, baseUrl wins.

Registered tools

Tools registered against an agent (via speko.agents.tools.create(...) or the dashboard) can be loaded and handed straight to complete(). listChatTools(agentId) fetches the agent's tools and converts every source kind — inline, webhook, builtin, and integration — into the ChatTool[] shape complete() expects:

const speko = new Speko({
  apiKey: process.env.SPEKO_API_KEY,
  baseURL: process.env.SPEKO_BASE_URL,
});

// Fetch once, then pass straight to complete()
const tools = await speko.agents.tools.listChatTools(agentId);

const { text, toolCalls } = await speko.complete({
  messages: [{ role: 'user', content: 'Book me a slot tomorrow at 3pm' }],
  intent: { language: 'en' },
  tools,
});

Webhook, builtin, and integration tools run server-side and are folded back into the response; inline tools come back to you as toolCalls to execute yourself.
