# Available Feeds

> All crypto price feeds with live examples.

## Feed reference

All feeds update at approximately one event per second. Prices are quoted in
USD. The examples below show explicitly selected spot events.

The same seven feed names apply to spot, 30-second TWAP, and 60-second TWAP
events. See [Chainlink Spot and TWAP Prices](/crypto/twap) for the current
default, explicit spot selection, and `twap_windows` filters.

## Filtering

Subscribe to specific feeds only:

```json theme={null}
{
  "action": "subscribe",
  "type": "chainlink",
  "filters": {
    "feeds": ["BTC/USD", "ETH/USD", "SOL/USD"]
  }
}
```

Feed names are case-insensitive. `"btc/usd"` and `"BTC/USD"` both work.

To receive spot prices for the selected feeds, add `price_source: "spot"`:

```json theme={null}
{
  "action": "subscribe",
  "type": "chainlink",
  "filters": {
    "feeds": ["BTC/USD", "ETH/USD", "SOL/USD"],
    "price_source": "spot"
  }
}
```

## Subscribing to all feeds

Omit the `feeds` filter to follow the default stream for all feeds:

```json theme={null}
{"action": "subscribe", "type": "chainlink"}
```

The default stream now sends both TWAP windows per feed. Add
`price_source: "spot"` for every spot pair, or select `twap_windows: [30]` or
`[60]` when your application needs only one TWAP lookback.
