Hyperliquid Market Data

Overview

This RapidAPI wrapper serves Hyperliquid market data — open interest, funding rates, and perpetual stats.

⚠️ Gotcha (verified 2026-08): the underlying Hyperliquid API (api.hyperliquid.xyz/info) is POST-only (GET returns 405) — always use POST with a JSON body.

Quick Start

The API is on RapidAPI (replace YOUR_RAPIDAPI_KEY):

curl -X POST "https://api.hyperliquid.xyz/info" \
  -H "Content-Type: application/json" \
  -d '{"type": "meta"}'

{ "universe": [ { "name": "BTC", "index": 0 } ], "perpMeta": { "universe": [ { "name": "BTC" } ] } }

Authentication

• The RapidAPI wrapper needs an x-rapidapi-key.
• The underlying Hyperliquid API is POST + JSON, keyless.

Rate Limits & Notes

• RapidAPI free tier with limits; Hyperliquid’s own API is free.
• Data types: meta, metaAndAssetCtxs (OI/funding), clearinghouseState, etc.
