---

name: ainative-auth-guide description: Implement authentication for AINative APIs. Use when (1) Choosing between API key and JWT auth, (2) Registering/logging in users, (3) Refreshing tokens, (4) Implementing OAuth2 (LinkedIn/GitHub), (5) Using API keys for server-side or agent use. Covers email/password, OAuth2 social login, API key management, and middleware patterns. Closes #1519.

AINative Authentication Guide

Auth Methods

| Method | Use Case | Header | |--------|----------|--------| | API Key | Server-side, agents, SDKs, MCP tools | X-API-Key: ak_... | | Bearer JWT | User sessions, web apps | Authorization: Bearer | | OAuth2 | Social login (LinkedIn, GitHub) | Standard OAuth2 flow |

API Key Auth (Simplest)

Get a key via npx zerodb init or from the dashboard.

import requests
response = requests.get(
    "https://api.ainative.studio/api/v1/public/credits/balance",
    headers={"X-API-Key": "ak_your_key"}
)

const res = await fetch("https://api.ainative.studio/api/v1/public/credits/balance", {
  headers: { "X-API-Key": "ak_your_key" }
});

Email/Password Registration & Login

# Register
resp = requests.post(
    "https://api.ainative.studio/api/v1/auth/register",
    json={"email": "user@example.com", "password": "securepass", "name": "Alice"}
)
token = resp.json()["access_token"]
Login
resp = requests.post(
    "https://api.ainative.studio/api/v1/auth/login",
    json={"email": "user@example.com", "password": "securepass"}
)
access_token = resp.json()["access_token"]
refresh_token = resp.json()["refresh_token"]

JWT Usage

headers = {"Authorization": f"Bearer {access_token}"}
me = requests.get("https://api.ainative.studio/api/v1/users/me", headers=headers).json()

Token Refresh

resp = requests.post(
    "https://api.ainative.studio/api/v1/auth/refresh",
    json={"refresh_token": refresh_token}
)
new_access_token = resp.json()["access_token"]

Logout

requests.post(
    "https://api.ainative.studio/api/v1/auth/logout",
    headers={"Authorization": f"Bearer {access_token}"}
)

OAuth2 Social Login

# LinkedIn
resp = requests.post(
    "https://api.ainative.studio/api/v1/auth/linkedin/callback",
    json={"code": oauth_code, "redirect_uri": "https://yourapp.com/callback"}
)
GitHub
resp = requests.post(
    "https://api.ainative.studio/api/v1/auth/github/callback",
    json={"code": oauth_code, "redirect_uri": "https://yourapp.com/callback"}
)
token = resp.json()["access_token"]

Next.js Middleware

// middleware.ts
import { createMiddleware } from '@ainative/next-sdk/middleware';
export const middleware = createMiddleware({
  apiKey: process.env.AINATIVE_API_KEY!,
  protectedPaths: ['/dashboard', '/api/protected'],
  loginPath: '/login',
});

Password Reset

# Request reset email
requests.post("https://api.ainative.studio/api/v1/auth/forgot-password",
    json={"email": "user@example.com"})
Set new password with token from email
requests.post("https://api.ainative.studio/api/v1/auth/reset-password",
    json={"token": "reset_token_from_email", "new_password": "newpassword"})

Auth Endpoints

| Endpoint | Method | Description | |----------|--------|-------------| | /api/v1/auth/register | POST | Create account | | /api/v1/auth/login | POST | Email/password → JWT | | /api/v1/auth/logout | POST | Invalidate session | | /api/v1/auth/refresh | POST | Refresh access token | | /api/v1/users/me | GET | Current user profile | | /api/v1/auth/verify-email | POST | Verify email address | | /api/v1/auth/forgot-password | POST | Send reset email | | /api/v1/auth/reset-password | POST | Apply new password | | /api/v1/auth/linkedin/callback | POST | LinkedIn OAuth2 | | /api/v1/auth/github/callback | POST | GitHub OAuth2 |
