How to call the API
Usually you create an API key in the platform console, then replace the SDK's baseURL, model name, and auth details per the docs. Test streaming, function calling, error codes, and rate limits before launch.
import OpenAI from "openai";
const client = new OpenAI({
apiKey: process.env.AI_GATEWAY_API_KEY,
baseURL: "https://your-gateway.example.com/v1"
});
const response = await client.chat.completions.create({
model: "gpt-4.1-mini",
messages: [{ role: "user", content: "Test one call through an AI gateway." }]
});
A third-party paid GPT API relay for developers in China, with an OpenAI-compatible endpoint at https://api.codexhot.com/v1. Its public guide lists GPT GO, PLUS, and PRO groups with models the platform reports as tested; group names do not establish official authorization or performance guarantees.

Payment
Price
The public guide displays default GO / PLUS / PRO multipliers of 0.02 / 0.07 / 0.1 against the platform's own model base billing, not fixed prices per request. Charges depend on model, group, input/output, caching, and request-time rules. Vouchers start at CNY 5; the submitter says they are purchased through the external wzyp.cn shop and redeemed on the website. Payment methods depend on that shop; AI Beyond could not verify its checkout page.

Is New API ready for production?
Run a small-traffic load test, rate-limit test, and error-code test first, and confirm the billing rules; keep a backup provider for important workloads.
