Quick start: Get your API key from the Bunny Platform, then send it in the X-API-Key header with every request.

​
What is Bunny?

Bunny is a developer API platform. Instead of hunting down third-party integrations, wiring up credentials, and handling inconsistent responses, you get a single key and a single base URL that covers the utility APIs every project eventually needs. Every API on Bunny follows the same conventions: REST endpoints, JSON responses, and a shared authentication header. You pay only for successful calls — errors and timeouts are always free. What Bunny is not: Bunny is not a database, a cloud provider, or a general-purpose compute platform. It is a focused catalog of production-ready utility APIs designed to ship fast and stay reliable.

One key

A single bun_ key unlocks all APIs you subscribe to. No per-service credentials.

Pay on success

Billing only triggers on 2xx responses. Failed calls cost nothing.

REST + JSON

All endpoints follow consistent REST conventions with JSON responses.

Base URL

All requests go to: https://api.bunny.build/api/v1

​
Get your API key

  1. Sign up at the Bunny Platform
  2. Create an API token (e.g. “Production API Key”)
  3. Copy the token. It starts with bun_ and is shown only once. Store it securely.

Authentication

Security check endpoints use API key authentication only. Include the header: X-API-Key: bun_your_api_key

​
First request

curl "https://api.bunny.build/api/v1/temporary-email?email=user@tempmail.com" \
  -H "X-API-Key: bun_your_api_key"
