hyperliquid-reader

description

Read Hyperliquid (app.hyperliquid.xyz) perp + spot market data via opencli (read-only, public info API). Use whenever the user wants Hyperliquid perpetual or spot markets, mark/oracle/mid prices, 24h change, funding rates (hourly or annualized APR), open interest, volume, the L2 order book, OHLCV candles, historical funding, or a cross-venue funding comparison (Hyperliquid vs Binance vs Bybit) for funding arbitrage. Triggers: "Hyperliquid funding for BTC", "HL perp markets", "funding on BTC perp", "Hyperliquid order book", "HL open interest", "funding arb Hyperliquid vs Binance", "Hyperliquid candles for SOL", "Hyperliquid spot markets", "PURR price on Hyperliquid", "hyperliquid", "hyperliquid.xyz", "HL DEX". READ-ONLY market data — no account, order, or trade operations.

Hyperliquid Reader (Read-Only)

Reads Hyperliquid — the on-chain perps/spot DEX — for market data via opencli and the hyperliquid plugin in this repo's opencli-plugins/hyperliquid tree (a separate plugin from opencli's built-in adapters, installed via opencli's monorepo subpath syntax).

This skill is read-only and market-data only. It reads Hyperliquid's fully public info API for analysis: market tables, funding, order book, and candles. It does NOT read individual accounts, place/modify/cancel orders, or move funds. There is no trading path in the plugin — order placement requires wallet-signed actions on a separate endpoint this adapter never calls.

How it works: every command issues a single POST https://api.hyperliquid.xyz/info with a { "type": "..." } body and normalizes the response. No API key, no wallet, no login, no running app — the info API is public.

Step 1: Ensure opencli + Plugin Are Installed and Ready

Current environment status:

!`(command -v opencli && opencli hyperliquid markets --coin BTC -f json 2>&1 | head -3 && echo "READY" || echo "SETUP_NEEDED") 2>/dev/null || echo "NOT_INSTALLED"`

If the status above shows READY, skip to Step 2. Otherwise:

NOT_INSTALLED — Install opencli

npm install -g @jackwener/opencli

Requires Node.js >= 22 (built-in fetch).

SETUP_NEEDED — Install the Hyperliquid plugin

The Hyperliquid adapter is not built into opencli — it's a separate plugin:

opencli plugin install github:himself65/finance-skills/hyperliquid

That's the entire setup — no auth, no launch step. Verify with opencli hyperliquid markets --coin BTC.

Common setup issues

Symptom	Fix
opencli: command not found	npm install -g @jackwener/opencli (Node ≥ 22)
Unknown command: hyperliquid	opencli plugin install github:himself65/finance-skills/hyperliquid
hyperliquid info 429	Rate limited — wait a few seconds and retry

Step 2: Identify What the User Needs

User Request	Command	Key Flags
Perp markets overview / top by volume	opencli hyperliquid markets	--sort, --limit, --coin
One perp's price + funding + OI	opencli hyperliquid markets --coin BTC	—
Spot pairs overview	opencli hyperliquid spot-markets	--sort, --limit, --pair, --canonical-only
All current mid prices	opencli hyperliquid mids	--coin <substring>
Order book for a coin	opencli hyperliquid book --coin ETH	--depth, --n-sig-figs
OHLCV candles	opencli hyperliquid candles --coin BTC --interval 1h	--limit
Historical funding for a coin	opencli hyperliquid funding-history --coin BTC	--hours, --limit
Funding arb: HL vs Binance vs Bybit	opencli hyperliquid funding-compare	--coin, --sort, --limit

---

Step 3: Execute the Command

General pattern

# Use -f json or -f yaml for structured output
opencli hyperliquid markets --sort fundingAprPct --limit 15 -f json
opencli hyperliquid funding-compare --sort hlVsBinancePct --limit 20 -f md
opencli hyperliquid candles --coin BTC --interval 4h --limit 50 -f csv
opencli hyperliquid book --coin ETH --depth 5 -f json

Key rules

1. Coin symbols are bare perp names — BTC, ETH, SOL, HYPE (no exchange prefix). Spot pairs are BASE/USDC (e.g. PURR/USDC); for book/candles you can pass either a perp coin or a spot pair.
2. markets is the default lens for "how is X / the market doing" — it carries mark/oracle/mid price, 24h change, hourly funding + APR, open interest (coins and notional), and 24h volume in one row per perp. Filter with --coin for a single asset.
3. Funding is reported two ways — fundingHrPct is the raw hourly rate as a percent; fundingAprPct annualizes it (hourly × 24 × 365). Lead with APR when comparing carry across assets; use the hourly figure for "what will I pay next hour".
4. funding-compare is the funding-arb screen — it annualizes each venue with its own interval (HL hourly, Binance/Bybit usually 4h) and reports hlVsBinancePct / hlVsBybitPct spreads. Default sort ranks by absolute HL-vs-Binance spread (widest dislocations first). A positive hlVsBinancePct means HL longs pay more than Binance longs.
5. book defaults to 10 levels per side — raise --depth (max 20) for more, or --n-sig-figs 2..5 to aggregate price levels. Compute the spread/mid from the top bid and ask.
6. candles pulls the most recent --limit candles of --interval (default 1h, 100 candles). Valid intervals: 1m 3m 5m 15m 30m 1h 2h 4h 8h 12h 1d 3d 1w 1M. Max 5000.
7. -f json for programmatic processing / feeding other skills; -f md or -f table for human-readable output.
8. NEVER call any write operation. This skill is read-only market data — no account reads, no order placement, modification, or cancellation, and no transfers. The plugin intentionally exposes no write endpoints.

Output format flag (-f)

Format	Flag	Best for
Table	-f table (default)	Human-readable terminal output
JSON	-f json	Programmatic processing, LLM context
YAML	-f yaml	Structured, readable
Markdown	-f md	Reports
CSV	-f csv	Spreadsheet export

Output columns

• markets — coin, markPx, midPx, oraclePx, change24hPct, fundingHrPct, fundingAprPct, openInterest, oiNotional, dayNtlVlm, premiumPct, maxLeverage
• spot-markets — pair, base, markPx, midPx, change24hPct, dayNtlVlm, circulatingSupply, marketCap, canonical
• mids — coin, mid
• book — side, level, px, sz, orders
• candles — time, open, high, low, close, volume, trades
• funding-history — coin, fundingRatePct, fundingAprPct, premiumPct, time
• funding-compare — coin, hlAprPct, binanceAprPct, bybitAprPct, hlVsBinancePct, hlVsBybitPct, nextHlFunding

Step 4: Present the Results

1. Lead with the headline number, then the table. For markets --coin BTC: state mark price, 24h change, funding APR, and open interest in prose first. For a full markets dump: lead with the count and the top movers / highest-funding names.
2. Frame funding in carry terms — e.g. "BTC perp funding is +10.9% APR (longs pay shorts)". Positive funding ⇒ longs pay shorts; negative ⇒ shorts pay longs.
3. For funding-compare, surface the widest dislocations first — name the coin, both venues' APRs, and the spread, and remember the spread is annualized; a real arb also pays exchange/withdrawal frictions, so present it as a screen, not a guaranteed edge.
4. For book, report the spread — best bid, best ask, mid, and spread in bps before (or instead of) dumping every level. Don't paste 20 levels unless asked.
5. For candles, describe the move — first/last close, high/low, and direction; only show the full OHLCV table when the user wants the series.
6. Filter aggressively before showing — markets has ~180 perps and mids ~700 markets; cap to top 15-20 by the relevant sort unless the user asks for the full list.
7. Cross-reference for trade decisions — Hyperliquid is the on-chain venue; for equities/options context pair it with the funda-data or tradingview-reader skills. For funding/basis trades, funding-compare plus markets (premium, OI) is the core view.

Step 5: Diagnostics

opencli hyperliquid markets --coin BTC

A successful BTC row confirms opencli, the plugin, and the public API are all reachable. If it errors with Unknown command: hyperliquid, reinstall the plugin (Step 1). A hyperliquid info 4xx/5xx is an upstream API issue — retry after a short wait.

Error Reference

Error	Cause	Fix
Unknown command: hyperliquid	Plugin not installed	opencli plugin install github:himself65/finance-skills/hyperliquid
hyperliquid info 429	Rate limited	Wait a few seconds, then retry
hyperliquid info 422/500	Malformed body or upstream issue	Re-check the coin/interval; retry after a wait
No perp market for coin "X"	Wrong/unlisted symbol	Run opencli hyperliquid markets (or mids) to find the exact symbol
