How do I estimate the cost of a call in JavaScript?

Read usage from the response and apply the price of the model id you called.

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.gateway.clatterlabs.xyz/v1",
  apiKey: process.env.CLATTER_API_KEY,
  defaultHeaders: { "X-Clatter-Account": process.env.CLATTER_ACCOUNT_ID },
});

const PRICES = { "supercosmos-flash": [1.6, 3.4], "supercosmos-max": [1.8, 3.8], "supercosmos-heavy": [2.0, 4.4] };

const r = await client.chat.completions.create({ model: "supercosmos-max", messages: [{ role: "user", content: "Hi" }] });
let [pin, pout] = PRICES[r.model];
if (r.usage.prompt_tokens > 262_000) pin *= 1.5; // long-context input
const cost = (r.usage.prompt_tokens * pin + r.usage.completion_tokens * pout) / 1e6;
console.log(`$${cost.toFixed(6)}`);

Billing rounds each call up to the next millionth of a dollar. The same call appears in Console › Logs with its price.

Every JavaScript example uses the same client (base URL, key and the X-Clatter-Account header); see Set up the JavaScript SDK. Full parameter list: Create a chat completion.
