Streaming and non-streaming endpoints

Standard REST API, works with any language

Base URLhttps://your-domain.com/api/v1

Auth Headerx-api-key: SUB-xxxxxxxx

Formatapplication/json

Authentication

The API supports two authentication methods. For programmatic access, use an API key via the x-api-key header. Browser-based access uses your JWT session cookie automatically.

Method 1

API Key — for programmatic/server use

Pass your subscription key in the x-api-key header. The key must belong to an account with an active subscription. Expired subscriptions return 403 even if the key is valid.

Method 2

JWT Cookie — for browser use only

When calling from the browser while logged in, the session cookie is used automatically. No additional headers needed. Preference routes require this method.

http

POST /api/v1/contenify/rewrite/stream
Content-Type: application/json
x-api-key: SUB-a3f4b8c9d2e1f0...

API Key Management

Manage your API key from Settings → API Key. Only one key exists per account; generating a new one revokes the previous key immediately.

Code Examples

JavaScript / Node.js — Streaming

javascript

const res = await fetch("https://your-domain.com/api/v1/contenify/rewrite/stream", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "x-api-key": "SUB-your-api-key-here"
  },
  body: JSON.stringify({
    article: "Your article text or scraped content...",
    language: "English",
    tone: "professional"
  })
});

const reader = res.body.getReader();
const decoder = new TextDecoder();

while (true) {
  const { done, value } = await reader.read();
  if (done) break;

  const lines = decoder.decode(value).split("\n");
  for (const line of lines) {
    if (line.startsWith("data: ")) {
      const data = JSON.parse(line.slice(6));
      if (data.type === "content") process.stdout.write(data.chunk);
      if (data.type === "complete") console.log("\nDone:", data.data.title);
    }
  }
}
