# Overview

> Reference overview for the Kyckr Companies V2 API — base URLs, authentication, and response format.

This section documents every Companies V2 endpoint, with request parameters, response schemas, and live examples.

New to the API? Start with the [Getting Started guide](/company-v2/guides/getting-started). For what's changed recently, see the [Changelog](/company-v2/api-reference/changelog).

## Base URL

| Environment | Base URL                        |
| ----------- | ------------------------------- |
| Production  | `https://api.kyckr.com/v2`      |
| Test        | `https://test-api.kyckr.com/v2` |

## Authentication

Every request requires your API key, sent in the `Authorization` header. See [Getting Started](/company-v2/guides/getting-started) for how to obtain and send your key.

## Response format

Responses share a common envelope:

* `correlationId` — a unique ID for the request; quote it in support enquiries.
* `timeStamp` — when the response was generated.
* `details` — a human-readable status message.
* `data` — the response payload, which varies by endpoint.

Asynchronous operations (orders) also return an `orderId` you can poll for the result.
