The Pyth contributors are excited to announce the Pyth Pro Proxy API (Beta). A simplified way to stream real-time price data without authentication.
What is the Proxy API?
The Proxy API gives developers instant access to Pyth Pro price feeds with zero setup friction: no API keys, no WebSocket handshakes, just clean HTTP endpoints.
It currently supports two endpoints:
| Method | Path | Description |
|---|---|---|
| GET | /v1/latest_price |
Fetch latest price for given feed IDs |
| GET | /v1/stream |
Stream continuous price updates (SSE) |
How fast is it?
The Proxy streams price updates every 200ms with only 400ms of delay. It makes it ideal for building responsive frontends, dashboards, monitoring tools, and rapid prototyping.
Getting Started
Getting prices is as simple as a single HTTP call:
# Latest price
https://pyth-lazer-proxy-3.dourolabs.app/v1/latest_price?price_feed_ids=1&price_feed_ids=2
# SSE stream
https://pyth-lazer-proxy-3.dourolabs.app/v1/stream?price_feed_ids=1&price_feed_ids=2

Note: This service is currently in beta and is not meant for production use. Interfaces, URLs, and availability may change without notice. For production workloads, use the WebSocket API or REST API.
Who is this for?
-
Developers who want to prototype quickly without managing access tokens.
-
Teams building price dashboards or monitoring tools.
