Built by developers, for developers
A clean REST + streaming API, typed SDKs in three languages, webhooks that just fire, and docs that answer the question before you have to ask it.
From zero to first generation in under a minute
Auth with a single key. Stream over HTTP. Webhooks for long-running jobs. No SDK lock-in — raw REST works too.
One API key
Bearer auth. Rotate anytime. Scoped keys for production.
99.98% uptime
Multi-region, edge-terminated. Status page + webhooks for incidents.
Webhooks
Signed, retried, idempotent. Know the moment a job finishes.
import { Sunesis } from "@sunesis/sdk";
const client = new Sunesis(process.env.SUNESIS_KEY);
// Stream expressive speech in any voice
const stream = await client.voice.stream({
voice: "aria",
text: "Hello — so glad you're here.",
emotion: "warm",
});
for await (const chunk of stream) {
speaker.write(chunk); // PCM audio
