Every Drin capability is reachable from one account and one key. Use the typed SDK in your language, the CLI for scripts and CI, the MCP server for agents — or talk to the REST API directly from anything that speaks HTTP.

TypeScript / Node

@drin00/sdk — typed client with retries, cursor pagination, and webhook verification.

Python

pip install drin — the official Python client, same surface as the TS SDK.

Go

Call the REST API with the standard net/http client — worked example below.

Ruby

Use Net::HTTP or your HTTP client of choice against the REST contract.

PHP

A few lines of curl or Guzzle — the same JSON body as everywhere else.

cURL / REST

No dependency. The raw HTTP contract, callable from any stack.

​
Install

npm install @drin00/sdk

​
TypeScript / Node

The official client mirrors the wire contract one-to-one, with built-in retries, async-iterator pagination, typed errors, and local webhook verification. 
import { DrinClient } from "@drin00/sdk";

const drin = new DrinClient({ apiKey: process.env.DRIN_API_KEY! });

const { id } = await drin.emails.send({
  from: { email: "hello@acme.com", name: "Acme" },
  to: [{ email: "customer@example.com" }],
  subject: "Welcome aboard",
  html: "<h1>You're in</h1>",
});

​
Python

Same surface, Pythonic names. Published to PyPI as drin. 
import os
from drin import DrinClient

drin = DrinClient(api_key=os.environ["DRIN_API_KEY"])

msg = drin.emails.send(
    from_={"email": "hello@acme.com", "name": "Acme"},
    to=[{"email": "customer@example.com"}],
    subject="Welcome aboard",
    html="<h1>You're in</h1>",
)
print(msg["id"])

​
Any language (REST)

No SDK? Every endpoint is a plain JSON request over HTTPS. Here’s the same send in Go, Ruby, and PHP. 
body, _ := json.Marshal(map[string]any{
    "from":    "Acme <hello@acme.com>",
    "to":      "customer@example.com",
    "subject": "Welcome aboard",
    "html":    "<h1>You're in</h1>",
})
req, _ := http.NewRequest("POST", "https://api.drin.run/v1/emails", bytes.NewReader(body))
req.Header.Set("Authorization", "Bearer "+os.Getenv("DRIN_API_KEY"))
req.Header.Set("Content-Type", "application/json")
resp, _ := http.DefaultClient.Do(req)
Account-wide keys also take a sender (your project’s external id) so requests are scoped correctly. Project-scoped keys don’t need it.
