Installation

Memsy ships official clients for Python and Node.js. Both are thin, typed HTTP clients with built-in retries, usage tracking, and identical method names. If neither matches your stack, the cURL tab on every page shows the raw HTTP call so you can wire it up in any language.

Requirements

Python: 3.10, 3.11, 3.12, or 3.13
OS: macOS, Linux, Windows
One dependency: httpx >=0.25, installed automatically

Node.js: 18.x or newer (uses the global fetch and AbortSignal.timeout)
Module formats: ESM and CommonJS both supported
TypeScript: types ship with the package — no @types/... install needed
Zero runtime dependencies

Any HTTP client works. The examples in these docs use curl for clarity, but you can use Postman, Insomnia, or your language's standard http library.

Install

pip install memsy

uv add memsy

poetry add memsy

pipenv install memsy

npm install @memsy-io/memsy

pnpm add @memsy-io/memsy

yarn add @memsy-io/memsy

bun add @memsy-io/memsy

Nothing to install — curl is preinstalled on macOS and most Linux distros. On Windows, use the bundled curl.exe (Windows 10+) or install it via winget install curl.

Verify the install

import memsy
print(memsy.__name__)          # 'memsy'
from memsy import MemsyClient  # no ImportError

import { MemsyClient } from '@memsy-io/memsy';
console.log(typeof MemsyClient); // 'function'

curl --version
# curl 8.x ...
