# FAQ

> Short answers to common Hyze Cloud API questions.

## Do I need an API key?

Yes. Private endpoints require `Authorization: Bearer hyze_your_key`.

## What is the API base URL?

Use `https://api.hyzecloud.com/api`.

## Which runtimes are supported?

Apps support Node.js, Bun, and Python.

## Which databases are supported?

Hyze Cloud supports PostgreSQL, MySQL, MongoDB, and Redis.

## Should I use the API or Dashboard?

Use the Dashboard for manual operations.

Use the API for CI/CD, internal tools, and automation.

## Where should secrets live?

Store secrets in app environment variables or your external secret manager.

Never commit them to source control.

## What does HTTP 429 mean on my website?

Hyze applies a **public proxy rate limit**. Too many requests from the same IP (or high total traffic on a subdomain) return `429` with `Retry-After`.

This does **not** mean your app was paused — the process keeps running. See [Rate limits](/en/concepts/rate-limits).
