Atlas API Reference

Build fast integrations with the Atlas API

Atlas helps teams sync accounts, stream events, and automate workflows across product surfaces. This guide walks through authentication, core patterns, and practical examples in JavaScript, Python, and cURL.

Base URL

https://api.atlasfiction.com

Auth

Bearer token or OAuth 2.0

Formats

JSON, NDJSON, webhooks

Introduction

Atlas is a fictional SaaS platform for managing customer accounts, tracking lifecycle events, and reacting to product signals. The API is optimized for predictable pagination, clear error handling, and secure server-to-server integrations.

What you can do

Create and manage customer accounts
Listen for events and deliver webhooks
Sync status changes into your stack
Generate reports and audit trails

Design principles

Stable resource identifiers
Idempotent write operations
Human-readable errors
Secure defaults and scoped access

Info

All examples in this page use the fictional Atlas sandbox environment. Replace sample tokens with a production key before shipping to users.

Quickstart

4 minutes

Get from zero to your first request in a few steps. The Atlas API uses standard HTTPS requests and JSON payloads, so any modern language or toolchain will work.

1. Create an API key in the Atlas dashboard.
2. Add the key to your environment as ATLAS_API_KEY.
3. Make your first request against the /v1/accounts endpoint.

Create an account

POST /v1/accounts

# cURL
curl https://api.atlasfiction.com/v1/accounts \
  -X POST \
  -H "Authorization: Bearer ATLAS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name":"Northstar Labs","plan":"pro"}'

Warning

Never expose secret API keys in frontend code. Use a server-side proxy or signed ephemeral tokens when building browser-based integrations.

Authentication

Atlas supports API keys for internal services and OAuth 2.0 for delegated access. Choose the model that fits your deployment and rotate credentials regularly.

API Keys

API keys authenticate as the workspace that issued them. They are ideal for backend automation, cron jobs, and service-to-service requests.

Authorization: Bearer ak_live_••••••••••••

OAuth 2.0

Use OAuth when end users grant Atlas access to their own data. Supported flows include Authorization Code and Client Credentials.

scope=accounts:read events:write webhooks:manage

Tip

Start with the narrowest scope set possible. It reduces blast radius and makes consent screens easier for customers to understand.

Objects

Every resource is represented as JSON with a stable id, a type, and a set of descriptive attributes.

Account object

{
  "id": "acc_01h8x4t2w9",
  "type": "account",
  "name": "Northstar Labs",
  "plan": "pro",
  "created_at": "2026-01-18T15:04:12Z"
}

Pagination

Atlas uses cursor pagination. Responses include a next_cursor field that you can pass back to retrieve the next page.

Best practice

Treat cursors as opaque. Do not parse or infer ordering logic from their format.

Errors

Errors are returned as JSON with a stable machine-readable code and a human-readable message.

Example response

{
  "error": {
    "code": "invalid_request",
    "message": "The plan field is required."
  }
}

Danger

Do not retry on validation errors. Fix the payload first; blind retries will only increase latency and noise in your logs.

Rate Limits

Atlas applies workspace-level quotas with per-route safeguards for bursty endpoints. Rate limit headers are returned on every response.

Limit

1,000 req/min

Burst

100 req/10 sec

Headers

X-RateLimit-*

List accounts

Returns a paginated list of accounts visible to the authenticated principal.

JavaScript

const client = new AtlasClient({ apiKey: process.env.ATLAS_API_KEY });
const accounts = await client.accounts.list({ limit: 20 });

Python

from atlas import AtlasClient
client = AtlasClient(api_key="ak_live_xxx")
accounts = client.accounts.list(limit=20)

cURL

curl https://api.atlasfiction.com/v1/accounts?limit=20 \
  -H "Authorization: Bearer ATLAS_API_KEY"

Create account

Creates a new Atlas account record. The request supports optional metadata for internal billing and CRM enrichment.

Retrieve account

Fetch a single account by ID. If the resource does not exist, Atlas returns a 404 with a helpful message.

List events

Events capture meaningful changes inside Atlas and can be consumed through the API or webhooks.

Webhooks

Webhook deliveries are signed with an HMAC header so your application can verify authenticity before processing payloads.

Tip

Respond quickly with a 2xx status and process work asynchronously. If your handler blocks, Atlas will retry delivery using exponential backoff.

JavaScript SDK

The Atlas SDK wraps authentication, pagination, and retries so you can focus on product logic.

Recipes
