What it is

Access a large collection of pre-existing APIs to speed up your app building process.

What you can make with it

Automations like: when a new Stripe customer signs up, add them to Notion and send a welcome email via Resend.

How it helps

Using this collection of APIs saves development time, especially for founders and developers, and helps them build applications without having to create APIs from scratch.

Real use case example

"A founder, Sarah, wants to automate the onboarding process for her new customers. She searches the API collection, finds a pre-existing API to connect to Stripe, and uses it to automatically add new customers to her Notion database. She then uses this API to trigger a welcome email through Resend. The API collection does the heavy lifting, freeing up Sarah to focus on the app's core features."

If you're new

Pick this up when you need to integrate simple automations into your project.

If you're senior

A senior engineer or developer would reach for this when they need to quickly access a reliable collection of APIs to accelerate their project.

Common confusion cleared up

Some people confuse this API collection with a generic list of APIs, but it's specifically designed to help developers and founders skip tedious tasks and build applications faster.
