What is the InspiroBot API?

InspiroBot's API is a single GET that returns the URL of a newly generated inspirational poster image as plain text, not JSON. It requires no API key or account, and each call produces a new, algorithmically generated poster.

This is the simplest API in the directory and it is worth documenting precisely because its response shape catches people out. `GET /api?generate=true` returns one line of `text/plain` containing an image URL — no JSON, no envelope, no fields. Calling `.json()` on the response fails; you want `.text()`. Once you have the URL you drop it straight into an `img` tag, and the image is already rendered and hosted on InspiroBot's own domain.

The content is machine-generated and deliberately absurd, which is the joke, but it is also the risk: nobody has read the poster before your users do, and the generator will occasionally produce something crass or grim. That is fine for a personal site or a chat bot among friends and a poor fit for anything customer-facing or aimed at children. There is no way to filter, regenerate-until-safe or moderate on the API side, so if the surface matters, put a human in the loop.

Quick facts

Base URL: https://inspirobot.me
Authentication: No key or account. There are no published terms for API use, so treat it as a favour rather than a service.
Rate limit: No published limit. Each call renders a new image server-side, so it is not free for the host — do not loop it.
Pricing: Free.
CORS: Enabled — callable directly from browser JavaScript

How to use the InspiroBot API

Every request below was executed against the live API on 2026-08-21, and the response shown is the real body it returned — not an illustration.

1. Generate a poster and get its URL

GET https://inspirobot.me/api?generate=true

curl

curl 'https://inspirobot.me/api?generate=true'

JavaScript (fetch)

const res = await fetch("https://inspirobot.me/api?generate=true");
if (!res.ok) throw new Error(`Request failed: ${res.status}`);
const data = await res.json();
console.log(data);

Python (requests)

import requests

res = requests.get("https://inspirobot.me/api?generate=true", timeout=20)
res.raise_for_status()
print(res.json())

Response — HTTP 200

Parameters

Parameter	Type	Required	Description
`generate`	boolean	Required	Must be `true`. This is the parameter that triggers generation. `true`
`season`	string	Optional	Optional themed variant, e.g. `xmas`, when the site is running one. `xmas`

Response fields

(response body)text/plain: A single line containing the URL of the generated image, on generated.inspirobot.me. There is no JSON structure at all — read it with `.text()`.

What you can build with the InspiroBot API

Add an absurd poster to a personal site or blog sidebar
Build a chat bot command that posts a generated poster
Demonstrate handling a plain-text API response in a teaching example
Fill a mock-up with images of a consistent shape and unpredictable content

Common errors and how to fix them

SyntaxError: Unexpected token in JSON

You called `.json()` on a plain-text response.

Fix: Use `.text()`. The body is a bare URL string with no JSON wrapper.

Empty response

The `generate=true` parameter is missing.

Fix: The bare `/api` path does nothing. `?generate=true` is what triggers a render.

Broken image after some time

Generated image URLs are not guaranteed to be permanent.

Fix: If you need a poster to persist, download and store the image yourself rather than hotlinking indefinitely.

InspiroBot API — frequently asked questions

How does the InspiroBot API work?

Send `GET https://inspirobot.me/api?generate=true` and the response body is a single plain-text line: the URL of a freshly generated poster image. Put that URL in an `img` tag. There is no JSON and no key.

Why does JSON.parse fail on the response?

Because the response is not JSON. It is `text/plain` containing one URL. Read it with `.text()` in fetch, or `response.text` in most HTTP clients.

Is the generated content safe to show users?

Not reliably. The posters are machine-generated and no one reviews them before you receive them; occasional output is crude or bleak. It is fine for personal projects and unwise for anything customer-facing without a human check.

Can I use InspiroBot images commercially?

There are no published API terms, so assume not without asking. The service is offered informally, and building a commercial product on an undocumented favour is a poor bet regardless of the licence position.
