SDKs

WhatIsUp ships an OpenAPI 3.1 spec at api.whatisup.dev/openapi.json. Generate a typed client in any language with one command.

TypeScript

pnpm add -D openapi-typescript
npx openapi-typescript https://api.whatisup.dev/openapi.json -o whatisup.d.ts

Then use it with fetch:

import type { paths } from './whatisup';
 
type SendBody = paths['/v1/channels/{id}/messages']['post']['requestBody']['content']['application/json'];
 
const res = await fetch(`https://api.whatisup.dev/v1/channels/${id}/messages`, {
  method: 'POST',
  headers: {
    Authorization: `Bearer ${process.env.WHATISUP_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({ type: 'text', to: '+155512345', text: 'hi' } satisfies SendBody),
});

Python

pip install openapi-python-client
openapi-python-client generate --url https://api.whatisup.dev/openapi.json

Go

go install github.com/oapi-codegen/oapi-codegen/v2/cmd/oapi-codegen@latest
curl https://api.whatisup.dev/openapi.json -o openapi.json
oapi-codegen -package whatisup -generate types,client openapi.json > whatisup.gen.go

Other languages

Anything that consumes OpenAPI 3.1 works: Rust (openapi-generator-cli), Ruby (openapi-generator), Java (openapi-generator), PHP, C#, Swift, Kotlin, Elixir, Clojure.

llms.txt

Agents pull a flat description of the entire surface from whatisup.dev/llms.txt and the long-form version at whatisup.dev/llms-full.txt.

First-party SDK

A first-party TypeScript SDK is on the roadmap. Until then, generation from the spec is the recommended path — it's actually what we'd ship under the hood anyway.
