How to use Ezkielyna API with the Vercel AI SDK

• Node.js 18+ with the ai and @ai-sdk/openai-compatible packages
• An Ezkielyna API key

1. 1Top up API Credit

   Open ezkielyna.store/api-credit, pick a pack and pay with QRIS, USDT (BEP-20 or Solana), Binance Pay or store balance. A redeem code appears on the order page once payment is confirmed. The balance does not expire and there is no monthly fee.

2. 2Redeem the code and create an API key

   Sign in at https://api.ezkielyna.store (if you have no account there, use the Ezkielyna Store sign-in button on that page), open Wallet and paste the redeem code. Then open API Keys and create a key. The Standard group covers DeepSeek, GLM, MiniMax, Qwen and Kimi K2.7; choose Auto if you also want Premium models such as Kimi K3, Claude or GPT with the same key.

3. 3Install the packages

   Add the AI SDK and its OpenAI-compatible provider to your project.

   npm install ai @ai-sdk/openai-compatible

4. 4Keep the key on the server

   Store the key in an environment variable. Call the API from server code (an API route, server action or script), never from the browser.

   export EZKIELYNA_API_KEY="sk-..."

5. 5Create the provider

   Create one provider instance and import it wherever you call a model. includeUsage adds token counts to streamed responses.

   import { createOpenAICompatible } from "@ai-sdk/openai-compatible";
   
   export const ezkielyna = createOpenAICompatible({
     name: "ezkielyna",
     apiKey: process.env.EZKIELYNA_API_KEY,
     baseURL: "https://api.ezkielyna.store/v1",
     includeUsage: true,
   });

6. 6Generate and stream text

   Pass a model name from the model list to the provider. Every model uses the same provider and key.

   import { generateText, streamText } from "ai";
   import { ezkielyna } from "./ezkielyna";
   
   const { text } = await generateText({
     model: ezkielyna("deepseek-v4.1-flash"),
     prompt: "Explain what an API gateway does in one sentence.",
   });
   console.log(text);
   
   const result = streamText({
     model: ezkielyna("glm-5.3"),
     prompt: "Write a short haiku about routing.",
   });
   for await (const part of result.textStream) process.stdout.write(part);

7. 7Switch models

   Change the model name, for example deepseek-v4-pro, glm-5.3-flash, qwen3.8-flash or minimax-m3 (all in the Standard group). Premium models need a key in the Premium or Auto group. Names, groups and prices are on the model list.

• 401: the key is wrong, disabled or the balance is empty.
• model not found or not available for your group: the name must match the model list exactly and your key group must cover it.
• Wrong base URL: use https://api.ezkielyna.store/v1 (the provider appends /chat/completions itself), not ezkielyna.store/v1.
• DeepSeek JSON mode: when you ask for JSON output, the prompt must contain the word JSON. This is DeepSeek's own rule.
