Gcore publishes official SDKs for Python and Go, both generated from the OpenAPI specification using Stainless. Method names and parameter names match the API reference exactly.

​
Choosing a client

All options call the same API — the choice depends on the context:
SituationRecommendation
Scripting, automation, CI/CDPython SDK or Go SDK
One-off inspection, debuggingcurl or HTTPie
Shell scriptscurl
Production Node.js servicesJavaScript fetch or axios (see below)
Production Python servicesPython SDK (sync or async)
Production Go servicesGo SDK
Terraform-managed infrastructureTerraform provider

​
SDK coverage

The Python and Go SDKs cover the full API surface: Cloud (instances, volumes, networking, Kubernetes, load balancers, and more), IAM, CDN, DNS, Object Storage, FastEdge, Streaming, and WAAP. All Cloud API endpoints have auto-generated SDK methods. The API reference code samples show the exact method name for each endpoint.

​
JavaScript

No dedicated JavaScript SDK is published. Use the built-in fetch API (Node.js 18+, all modern browsers) or axios.

​
fetch (Node.js 18+)

const BASE_URL = 'https://api.gcore.com';
const TOKEN = process.env.GCORE_API_KEY;

// GET — verify token
const res = await fetch(`${BASE_URL}/iam/clients/me`, {
  headers: { Authorization: `APIKey ${TOKEN}` },
});
const account = await res.json();
console.log(account.id, account.email);

// POST — create a network
const netRes = await fetch(
  `${BASE_URL}/cloud/v1/networks/${process.env.PROJECT_ID}/${process.env.REGION_ID}`,
  {
    method: 'POST',
    headers: {
      Authorization: `APIKey ${TOKEN}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({ name: 'my-network' }),
  }
);
const { tasks } = await netRes.json();
console.log('Task ID:', tasks[0]);

​
axios

npm install axios

const axios = require('axios');

const client = axios.create({
  baseURL: 'https://api.gcore.com',
  headers: { Authorization: `APIKey ${process.env.GCORE_API_KEY}` },
});

const { data: account } = await client.get('/iam/clients/me');
console.log(account.id, account.email);

const { data } = await client.post(
  `/cloud/v1/networks/${process.env.PROJECT_ID}/${process.env.REGION_ID}`,
  { name: 'my-network' }
);
console.log('Task ID:', data.tasks[0]);

​
Handle async operations

Cloud API write operations return a task ID. Poll it until state is FINISHED: 
async function waitForTask(taskId, intervalMs = 5000) {
  const headers = { Authorization: `APIKey ${process.env.GCORE_API_KEY}` };
  while (true) {
    const res = await fetch(`https://api.gcore.com/cloud/v1/tasks/${taskId}`, { headers });
    const task = await res.json();
    if (task.state === 'FINISHED') return task.created_resources;
    if (task.state === 'ERROR') throw new Error(`Task failed: ${task.error}`);
    await new Promise(r => setTimeout(r, intervalMs));
  }
}

const { tasks } = await netRes.json();
const resources = await waitForTask(tasks[0]);
console.log('Network ID:', resources.networks[0]);
