# Public

Public Authentication does not require users to present credentials or tokens to access the API. Instead, the API is open for unrestricted access, ensuring ease of use for public data consumption or service interaction.

#### How to implement it in API Builder 

1. Open your project 
2. Near the name click on three vertical dots , click on settings.
3. Choose Public access level

**Example Use Case**

A municipal government provides an API to access real-time public transit schedules and routes. The API is publicly accessible, allowing developers to build applications that help commuters with transit planning without requiring individual user authentication.
