# Versioning and support

> How the API changes over time, and how to reach us.

## Versioning

The major version is in the path (`/v1`). Within v1 we only add things: new endpoints, new fields, and new values in enums documented as extensible. Write clients that ignore unknown fields and handle unknown enum values. Breaking changes ship in a new major version.

Credit prices are versioned per endpoint. Every response reports the version it was charged at in `X-Credit-Price-Version`; send that header back to make a request fail with `409 price_changed` instead of running at a new price.

Every endpoint is currently in beta.

## Changelog

`GET /v1/changelog` (free, no key needed) lists new features, deprecations with their sunset dates, data corrections with the affected dataset and range, and incidents. Pass `since` to fetch only new entries.

## Status

`GET /v1/status` (free, no key needed) reports each dataset's health (`ok`, `degraded`, `stale`, or `unknown`), its live lag and, where available, its `complete_to`.

## Support

Email [sales@hyperdash.com](mailto:sales@hyperdash.com) and quote the `request_id` from the response.
