FAQ

Find answers to common questions about this symbol and its data.

What is the latest price of Profusa (PFSA.US)?

Profusa (PFSA.US) The price on this page updates once per trading day after the session closes. For a live quote, use the REST endpoint or WebSocket stream in the API playground above.

How do I get real-time PFSA.US data from an API?

POST the Infoway REST endpoint at data.infoway.io/stock/v2/batch_kline. Put your API key in the request header, and send a JSON body with codes=PFSA.US, klineType (1-minute through yearly), and klineNum. It returns the latest OHLCV bars for PFSA.US — open, high, low, close, volume, and percent change. Enter PFSA.US and your key in the REST tab of the playground above to see the full request and response.

How do I get historical OHLCV data for PFSA.US?

Use the same kline endpoint with a daily interval and a bar count, and it returns up to that many daily candles for PFSA.US ending at the latest completed session. Each candle carries a Unix timestamp, open/high/low/close, volume, and turnover. For intraday history, change the interval to minutes or hours; for a fixed date window, filter the returned candles by timestamp. The playground above generates ready-to-run PFSA.US samples in Java, Go, Python, JavaScript, PHP, and cURL.

How do I stream live PFSA.US prices over WebSocket?

Open a connection to the Infoway WebSocket endpoint, authenticate with your API key, and send a subscribe message listing PFSA.US. You then receive a push on every bar update for PFSA.US with price, size, and timestamp. A single connection can subscribe to many symbols at once. The WebSocket tab in the playground above has a runnable example pre-filled with PFSA.US.
