Authentication
Every request must include your API key in the Authorization header.
http·Header
Authorization: Bearer px_live_…Keys
- Keys are created under Settings → API keys and shown only once.
- Prefix:
px_live_ - Each key is scoped to your PostAxis user — never another user's data.
- Only a SHA-256 hash of the key is stored server-side.
Subscription requirement
API access requires an active or trialing PostAxis subscription. Otherwise the API returns 403.
