X-API-Key header or as a Bearer token.
Getting an API Key
You can generate a new API key in the Free Tier Signup (email only) or the Paid Tier (requires credit card). Use a Free Sandbox Key for 5,000 free transactions/month, or a Paid Production Key at a flat $0.001/transaction from the first request.Making Authenticated Requests
Option 1: X-API-Key Header (Recommended)
Option 2: Bearer Token
Managing Your API Keys
You can view, rotate, and revoke your API keys at any time from the Key Dashboard. Sign in with the email address you used at checkout — no password required. We’ll send you a one-time magic link valid for 15 minutes.Rotating a Key
Rotation revokes your current key and issues a new one atomically. Use this if your key is compromised or if you want to cycle it on a schedule. Your subscription and usage quota carry over automatically — there is no downtime.Revoking a Key
Revocation permanently deactivates a key without issuing a replacement. Use this if you have multiple keys and want to retire one. Your other active keys are unaffected.Lost Your Key?
We send a copy of your raw API key to your email at the moment of provisioning. Check your inbox for an email from[email protected] with the subject “Your ParseTx API key”.
If you can’t find that email, sign in to the Key Dashboard and rotate your key. This immediately issues a new key and revokes the old one.
We cannot retrieve a lost raw key — only you ever saw it. Rotation is the intended recovery path and takes under 10 seconds.
Security Model
Your API keys are highly sensitive. To protect you from database leaks:- We never store your raw API key. Only a SHA-256 hash is persisted in our database.
- All inbound keys are hashed before lookup — a compromised database reveals no usable keys.
- Keys are prefixed
ptx_live_so they are identifiable and catchable by secret-scanning tools (e.g. GitHub secret scanning, GitGuardian). - Key rotation is instant and atomic — the old key stops working the moment the new one is issued.
