API Stock vs AIMLAPI

AIMLAPI alternative

Compare AIMLAPI and API Stock on shared Seedream image models, billing units and migration steps. Use one prepaid balance for media generation and chat requests.

How API Stock compares with AIMLAPI

When to choose API Stock

Choose API Stock when you want a consistent media-task lifecycle alongside OpenAI-compatible chat, and can adapt your image client to asynchronous results.

When to keep AIMLAPI

Check AIMLAPI for models or capabilities missing from our catalog. OpenAI-compatible chat and image generation use different migration paths; do not assume changing the base URL moves every endpoint.

Pricing

Migrating from AIMLAPI

For chat, replace the OpenAI SDK base URL, key and model id. For images, replace /v1/images/generations with /api/v1/generation/create, use the catalog model id and handle the returned taskId asynchronously.

  1. 1

    Create an account, top up your prepaid balance and issue an API key.

  2. 2

    POST to /api/v1/generation/create with the public model id and its documented parameters. Each task generates one output.

  3. 3

    Read taskId from the response. Poll GET /api/v1/task/status/TASK_ID, or set webhook in the creation request.

Complete example: create a task and download its result

Run on your server with Node 22+ or Bun and API_KEY set. This example creates one paid task, then polls without creating it again. Finished URLs are temporary: save the file to your own storage.

javascript
import { writeFile } from "node:fs/promises";
const baseURL = "https://api.api-stock.com/api/v1";
const apiKey = process.env.API_KEY;
if (!apiKey) throw new Error("Set API_KEY on the server");
async function request(path, options = {}) {
const response = await fetch(baseURL + path, {
...options,
headers: {
Authorization: `Bearer ${apiKey}`,
"Content-Type": "application/json",
},
signal: AbortSignal.timeout(30_000),
});
if (!response.ok) throw new Error(await response.text());
return response.json();
}
const { taskId } = await request("/generation/create", {
method: "POST",
body: JSON.stringify({
"model": "seedream-4-5",
"prompt": "A ceramic mug on a wooden table, soft morning light",
"resolution": "2K",
"size": "1:1"
}),
});
if (!taskId) throw new Error("Missing taskId");
const deadline = Date.now() + 10 * 60_000;
let fileUrl;
while (Date.now() < deadline) {
const { data } = await request(`/task/status/${encodeURIComponent(taskId)}`);
if (data.status === "finished") {
fileUrl = data.files?.[0]?.fileUrl;
if (!fileUrl) throw new Error("Task finished without a file");
break;
}
if (data.status === "failed" || data.status === "expired") {
throw new Error(data.errorMessage || data.status);
}
await new Promise((resolve) => setTimeout(resolve, 2000));
}
if (!fileUrl) throw new Error(`Still processing: save taskId ${taskId} and resume polling`);
const file = await fetch(fileUrl, { signal: AbortSignal.timeout(60_000) });
if (!file.ok) throw new Error(`Download failed: ${file.status}`);
const mime = file.headers.get("content-type")?.split(";")[0];
const extension = { "image/png": "png", "image/jpeg": "jpg", "image/webp": "webp" }[mime] || "bin";
await writeFile(`generated-image.${extension}`, new Uint8Array(await file.arrayBuffer()));

Keep API keys on your server. When migrating, test one request and compare its parameters, status handling and output before moving production traffic.

Frequently asked questions

How do I migrate from AIMLAPI?

For chat, replace the OpenAI SDK base URL, key and model id. For images, replace /v1/images/generations with /api/v1/generation/create, use the catalog model id and handle the returned taskId asynchronously.

Is API Stock always cheaper than AIMLAPI?

No. Compare the exact model, configuration and billing unit in the table. Prices can move in either direction; check both catalogs before sending production traffic.

Can I move every AIMLAPI workflow?

Check AIMLAPI for models or capabilities missing from our catalog. OpenAI-compatible chat and image generation use different migration paths; do not assume changing the base URL moves every endpoint.

What happens to failed or unfinished requests?

Media tasks retry according to the configured routes; a reserve is used when one is available. A terminal generation failure is refunded. Keep polling a processing task instead of creating a duplicate. An expired file URL is not a failed generation.

How do I top up the balance?

Available payment methods, currencies and minimum top-up amounts are shown in your account before payment. There is no subscription: model usage is charged to your prepaid balance.
