DATANODE API docs

These pages describe endpoints that are implemented on this site. Base URL: https://datanode-api.whop.site/api/v1

Getting started

1. Introduction. DATANODE is a JSON HTTP API. Send Content-Type: application/json on POST requests.
2. Account setup. Buy DATANODE Pro for $49.90 once, then sign in to the dashboard.
3. Authentication. Create a key and send Authorization: Bearer dn_live_….
4. First request. Try GET /api/v1/utils/uuid or the cURL sample on the home page.

Authentication

Create keys in the dashboard. The full secret is shown once.
Send the secret in the Authorization header. Query-string keys are rejected.
Store secrets in your environment, not in client-side JavaScript you ship to browsers.
Revoke a leaked key in the dashboard, then create a replacement.
Keys only work while DATANODE Pro access is active on the Whop account that created them.

Authorization: Bearer dn_live_<payload>.<signature>

Endpoints
