Authentication

API keys

All requests to /v1/solve use a bearer API key:

Authorization: Bearer rdn_sk_...

Keys are 71 characters: rdn_sk_ prefix + 64 hex chars. They are stored as HMAC-SHA256 hashes — the raw key is never persisted server-side.

Getting your key

Your key is shown once on first login and after each regeneration in the dashboard.

Caution

Copy your key immediately. You cannot retrieve it again — only regenerate a new one, which instantly invalidates the old one.

Rotating your key

Click regenerate in the dashboard. This immediately invalidates the current key and shows the new one once.

Best practices

• Store keys in environment variables, never in source code
• Rotate after suspected exposure
• Use separate keys for staging and production environments

.env

RAIDEN_API_KEY=rdn_sk_...

Node.js

const key = process.env.RAIDEN_API_KEY;

const resp = await fetch('https://api.raiden.dev/v1/solve', {
  headers: { Authorization: `Bearer ${key}` },
  // ...
});
