Do I need an API key?

No – the Advice Slip API works without any authentication or rate‑limit key.

How often does the advice change?

Each request returns a fresh random advice slip, drawn from a large pool of pre‑written advice strings.

Can I request a specific advice ID?

The public endpoint only supports random advice. For a specific ID you can use the `/advice/:id` endpoint documented on the site.

Advice Slip - Free Random Advice API (No Auth)

TL;DR

What it does: Returns a random piece of advice as JSON.

Quick start: curl "https://api.adviceslip.com/advice"

No API key required – free forever

Overview

The Advice Slip API delivers a random quote of wisdom with each request. The response is tiny (under 200 bytes), making it perfect for micro‑services, chat‑bots, or adding a bit of personality to UI elements. Because it’s completely public, you can call it directly from browsers without dealing with CORS or authentication.
