🛠️ Solution

Root Cause

The official Notion API domain https://www.notion.so/api/v3 may be rate-limited or experiencing DNS issues, causing failed requests. Temporary workaround: Use a custom Notion personal API domain instead of the official API.

✅ Temporary Fix Steps

1. Obtain Your Notion Personal API Domain

Open your shared Notion page (make sure it's publicly accessible).

Copy the URL from your browser’s address bar (format below): (Example: https://alice.notion.site/My-Blog-1234567890abcdef)

2. Construct the API URL

Extract your custom domain (https://[your-name].notion.site), then append /api/v3, e.g.:

3. Configure Vercel Environment Variable

Go to Vercel project → Settings → Environment Variables

Add a new variable:

Save and redeploy.

4. (Optional) Local Testing

If running the project locally, add this to local.env:

Then restart the project.

📌 Additional Notes

⚠️ Do NOT share the same API URL—traffic overload may lead to blocking!

🚀 After Notion Recovers: Remove API_BASE_URL to fall back to the official API.

💡 Ensure NotionNext is updated, as older versions may not support this variable.
