TypeScript SDK

Installation

npm install @avala-ai/sdk

yarn add @avala-ai/sdk

pnpm add @avala-ai/sdk

Quick Start

import Avala from "@avala-ai/sdk";

const avala = new Avala({ apiKey: "your-api-key" });

const datasets = await avala.datasets.list();
for (const dataset of datasets.items) {
  console.log(dataset.name, dataset.uid);
}

Create an Account

The signup function creates a new Avala account and returns an API key. It does not require authentication.

import { signup } from "@avala-ai/sdk";

const result = await signup({
  email: "dev@acme.com",
  password: "SecurePass123!",
  firstName: "Jane",       // optional
  lastName: "Doe",         // optional
});

console.log(`User: ${result.user.email}`);
console.log(`API Key: ${result.apiKey}`);

Use the returned API key to initialize the client:

import Avala, { signup } from "@avala-ai/sdk";

const { apiKey } = await signup({ email: "dev@acme.com", password: "SecurePass123!" });
const avala = new Avala({ apiKey });

Authentication

The SDK authenticates using your Avala API key, which is sent via the X-Avala-Api-Key header on every request. You can provide the key directly or let the SDK read it from the environment. Option 1: Pass the key directly

import Avala from "@avala-ai/sdk";

const avala = new Avala({ apiKey: "your-api-key" });

Option 2: Use an environment variable

export AVALA_API_KEY="your-api-key"

import Avala from "@avala-ai/sdk";

// Automatically reads AVALA_API_KEY from the environment
const avala = new Avala();

Working with Datasets

The TypeScript SDK is currently read-only for datasets — you can list and retrieve datasets but not create, update, or delete them. Use the REST API for uploads and mutations.

List Datasets

const datasets = await avala.datasets.list();

for (const dataset of datasets.items) {
  console.log(`${dataset.name} (${dataset.uid})`);
  console.log(`  Items: ${dataset.itemCount}`);
  console.log(`  Created: ${dataset.createdAt}`);
}

Get a Dataset

const dataset = await avala.datasets.get("550e8400-e29b-41d4-a716-446655440000");

console.log(dataset.name);
console.log(dataset.slug);
console.log(dataset.itemCount);

Working with Projects

List Projects

const projects = await avala.projects.list();

for (const project of projects.items) {
  console.log(`${project.name} (${project.uid})`);
  console.log(`  Status: ${project.status}`);
  console.log(`  Created: ${project.createdAt}`);
}

Get a Project

const project = await avala.projects.get("770a9600-a40d-63f6-c938-668877660000");

console.log(project.name);
console.log(project.status);

Working with Tasks

List Tasks

const tasks = await avala.tasks.list({
  project: "770a9600-a40d-63f6-c938-668877660000",
  status: "pending",
});

for (const task of tasks.items) {
  console.log(`${task.uid} — ${task.name} (${task.status})`);
}

Get a Task

const task = await avala.tasks.get("990c1800-b62f-85a8-e150-880099880000");

console.log(task.name);
console.log(task.status);

Working with Exports

Create an Export

const exportJob = await avala.exports.create({
  project: "770a9600-a40d-63f6-c938-668877660000",
});

console.log(`Export started: ${exportJob.uid}`);
console.log(`Status: ${exportJob.status}`);

Poll for Completion

let exportJob = await avala.exports.create({
  project: "770a9600-a40d-63f6-c938-668877660000",
});

while (exportJob.status !== "completed") {
  await new Promise((resolve) => setTimeout(resolve, 2000));
  exportJob = await avala.exports.get(exportJob.uid);
  console.log(`Status: ${exportJob.status}`);
}

console.log(`Download: ${exportJob.downloadUrl}`);

TypeScript Types

The SDK exports full TypeScript interfaces for all API objects. Use them to type your functions and variables.

import Avala from "@avala-ai/sdk";
import type { Dataset, Project, Export, Task, CursorPage } from "@avala-ai/sdk";

function processDataset(dataset: Dataset): void {
  console.log(dataset.name);       // string
  console.log(dataset.uid);        // string
  console.log(dataset.itemCount);  // number
  console.log(dataset.createdAt);  // string | null
}

function processTask(task: Task): void {
  console.log(task.uid);           // string
  console.log(task.name);          // string | null
  console.log(task.status);        // string | null
  console.log(task.project);       // string | null
}

Error Handling

The SDK throws typed errors so you can handle different failure modes precisely.

import Avala, { AvalaError, NotFoundError, RateLimitError } from "@avala-ai/sdk";

const avala = new Avala();

try {
  const dataset = await avala.datasets.get("nonexistent");
} catch (error) {
  if (error instanceof NotFoundError) {
    console.log(`Dataset not found: ${error.message}`);
  } else if (error instanceof RateLimitError) {
    console.log(`Rate limited. Retry after ${error.retryAfter} seconds.`);
  } else if (error instanceof AvalaError) {
    console.log(`API error (${error.statusCode}): ${error.message}`);
  } else {
    throw error;
  }
}

Exception	Description
`AvalaError`	Base error class for all Avala API errors.
`AuthenticationError`	Invalid or missing API key (HTTP 401).
`NotFoundError`	The requested resource does not exist (HTTP 404).
`RateLimitError`	You have exceeded the API rate limit (HTTP 429). Includes a `retryAfter` property.
`ValidationError`	The request payload failed validation (HTTP 400/422).
`ServerError`	The server returned an internal error (HTTP 5xx).

Pagination

List methods return a CursorPage<T> object with cursor-based pagination.

// Access items on the current page
const page = await avala.datasets.list({ limit: 10 });
for (const dataset of page.items) {
  console.log(dataset.name);
}

// Fetch the next page
if (page.hasMore) {
  const nextPage = await avala.datasets.list({
    limit: 10,
    cursor: page.nextCursor!,
  });
}

Working with Agents

Create an Agent

const agent = await avala.agents.create({
  name: "QA Bot",
  events: ["task.completed"],
  callbackUrl: "https://example.com/webhook",
  taskTypes: ["annotation"],
});

List Agent Executions

const executions = await avala.agents.listExecutions(agent.uid);
for (const exec of executions.items) {
  console.log(`${exec.eventType} — ${exec.status}`);
}

Working with Webhooks

Create a Webhook

const webhook = await avala.webhooks.create({
  targetUrl: "https://example.com/webhook",
  events: ["task.completed", "export.ready"],
});

Inspect Deliveries

const deliveries = await avala.webhookDeliveries.list();
for (const d of deliveries.items) {
  console.log(`${d.eventType} — ${d.status} (attempts: ${d.attempts})`);
}

Working with Quality & Consensus

Create a Quality Target

const target = await avala.qualityTargets.create("proj_uid", {
  name: "Accuracy",
  metric: "accuracy",
  operator: "gte",
  threshold: 0.95,
  notifyEmails: ["alerts@example.com"],
});

Check Consensus

const summary = await avala.consensus.getSummary("proj_uid");
console.log(`Mean score: ${summary.meanScore}`);
console.log(`Coverage: ${summary.itemsWithConsensus}/${summary.totalItems}`);

Fleet Management

Fleet Management is in preview. APIs described here may change.

The fleet namespace provides access to device registry, recordings, events, rules, and alerts.

// List online devices
const devices = await avala.fleet.devices.list({ status: "online" });

// Create a timeline event on a recording
const event = await avala.fleet.events.create({
  recordingId: "rec_abc123",
  timestamp: "2026-01-15T10:30:00Z",
  type: "anomaly",
  label: "Gripper force spike",
  metadata: { force_n: 45.2 },
});

// Create a recording rule
const rule = await avala.fleet.rules.create({
  name: "High Latency Alert",
  condition: { type: "threshold", topic: "/diagnostics/latency", field: "data.value", operator: "gt", value: 100 },
  actions: [{ type: "tag", value: "high-latency" }, { type: "notify", channelId: "ch_your_channel_id" }],
});

See the Fleet Dashboard guide for complete examples.

Configuration

You can customize the client behavior at initialization time.

import Avala from "@avala-ai/sdk";

const avala = new Avala({
  apiKey: "your-api-key",
  baseUrl: "https://api.avala.ai/api/v1", // Default
  timeout: 60_000,    // Request timeout in ms (default: 30000)
});

Parameter	Type	Default	Description
`apiKey`	`string`	`AVALA_API_KEY` env var	Your Avala API key.
`baseUrl`	`string`	`https://api.avala.ai/api/v1`	The API base URL.
`timeout`	`number`	`30000`	Request timeout in milliseconds.

Zero Dependencies

The @avala-ai/sdk package has zero runtime dependencies. It uses the native fetch API available in Node.js 18+, Deno, and Bun.

Framework Examples

Next.js (App Router)

// app/api/datasets/route.ts
import Avala from "@avala-ai/sdk";
import { NextResponse } from "next/server";

const avala = new Avala({ apiKey: process.env.AVALA_API_KEY! });

export async function GET() {
  const datasets = await avala.datasets.list();
  return NextResponse.json(datasets);
}

Express

import express from "express";
import Avala from "@avala-ai/sdk";

const app = express();
const avala = new Avala(); // Reads AVALA_API_KEY from env

app.get("/datasets", async (req, res) => {
  try {
    const datasets = await avala.datasets.list();
    res.json(datasets);
  } catch (error) {
    res.status(500).json({ error: "Failed to fetch datasets" });
  }
});

app.listen(3000, () => {
  console.log("Server running on port 3000");
});
