Email API built for developers
Send transactional and marketing emails through Resend's modern API. Let Keystore manage your API key securely.
Use Resend through Keystore with zero code changes. Keys are resolved from the vault and injected at request time.
import Keystore from "@keystore/sdk";
import { Resend } from "resend";
const ks = new Keystore({ agentToken: process.env.KS_TOKEN! });
ks.interceptAll();
const resend = new Resend("placeholder");
await resend.emails.send({
from: "agent@yourapp.com",
to: "user@example.com",
subject: "Hello from Keystore",
text: "Your agent sent this email securely.",
});Get started in minutes. Your credentials are encrypted and never exposed to your agent code.
