Action Required: Pyth Pro History API Auth Required Starting July 24

Announcements
1

Hey everyone,

Starting July 24, 2026, the following Pyth Pro History API endpoints will require API key authentication:

  • GET /v1/{channel}/price
  • GET /v1/{channel}/history
  • POST /v1/price

API key authentication is already supported in production today. Please update your requests to include:

http
Authorization: Bearer <PYTH PRO API KEY>

If you call these endpoints from a browser or frontend app, do not expose your API key client-side. The recommended setup is to route requests through your own backend or proxy.

For frontend apps that need a client-safe option and do not want to run their own proxy, we expect JWT-based authentication to be available around July 10.

Unauthenticated access to these endpoints will be disabled on July 24.

Quick update for teams using these endpoints from a browser/frontend:

The preferred setup is still to keep your Pyth Pro API key server-side, behind your own backend or proxy. Please don’t expose the API key directly in client-side code.

For teams that need a frontend-safe option and don’t want to route every request through their own proxy, the JWT auth flow is now available here:

The basic flow is:

  1. Your browser client asks your backend for a JWT.
  2. Your backend calls POST /auth/token using your secret Pyth Pro API key.
  3. Your backend returns the JWT to the browser client.
  4. The browser client uses that JWT as a bearer token:
Authorization: Bearer _*_
