Call an AI API in Node.js

Calling an AI API from Node.js takes a single HTTP request. Define your endpoint's behavior as a prompt on Svivva, then call it like any other JSON API from your Node.js code.

Node.js example

const res = await fetch("https://your-endpoint.example/run", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ text: "Summarize this article in two sentences." }),
});
if (!res.ok) throw new Error(`HTTP ${res.status}`);
const { result } = await res.json();
console.log(result);

Notes

• The endpoint is a normal HTTPS URL — no SDK required.
• Send your input as JSON; read the structured result from the response.
• Add a timeout and check the status code, as shown above.

Frequently asked questions

Do I need an SDK to call an AI API in Node.js?

No. Any Node.js HTTP client works because the endpoint is plain HTTPS + JSON.

How do I change the AI behavior?

Edit the prompt that defines the endpoint. Your Node.js code and the request contract stay the same.

Is this production-ready?

Yes — add input validation, a timeout, and error handling (shown above), and you can ship it.
