Perps and prices
Perpetual markets, funding, open interest and liquidations, next to a free Hermes-compatible oracle.
Perpetual markets
GET /perpslists markets with mark, oracle price, funding and open interest, sorted by volume, trades or price change over 5m to 24h.GET /perps/{market}/historyis the open interest, funding and mark series of one market.GET /perps/liquidationsgives daily liquidations of a market or a whole venue, Hyperliquid by default.
Typical uses: funding-rate dashboards, basis and carry monitors, liquidation alerts, and an agent that answers "what just blew up".
Prices for a protocol
Astra serves a composite exchange index over Pyth Hermes' routes and JSON, free and
keyless: point a Hermes client at https://astra.preview.avee.tech and it works. Latest and historical prices, SSE and
WebSocket streams. See Switch from Pyth Hermes.
The same prices are in the data API as GET /prices, so one client
reads markets and oracle together.
