okx-cex-market

This skill should be used when the user asks for 'price of BTC', 'ETH ticker', 'show me the orderbook', 'market depth', 'BTC candles', 'OHLCV chart data', 'f...

Security Scan

The skill's stated purpose (public OKX market data via an `okx` CLI) is plausible and mostly consistent, but there are small inconsistencies and an install-time risk that the user should review before installing the CLI it recommends.

Purpose & Capability

The skill claims to provide public, read-only OKX market data and the SKILL.md shows only read-only command examples. Requiring an `okx` CLI to fetch market data is reasonable. Minor note: the CLI package name (@okx_ai/okx-trade-cli) implies trading capabilities beyond read-only market calls, so installing that package could install functionality not restricted to read-only actions.

Instruction Scope

The runtime instructions only show read-only market commands and do not instruct the agent to read unrelated files, secrets, or system configuration. There is no instruction to access environment variables or user files beyond installing and running the CLI.

Install Mechanism

SKILL.md includes an npm install recommendation (global install of @okx_ai/okx-trade-cli). Installing a third-party npm CLI globally is a moderate-risk action because it writes executables to the system and the package may include non-read-only capabilities. Also: the registry metadata earlier listed 'No install spec — instruction-only', but SKILL.md contains an embedded install metadata block; that mismatch should be resolved. No direct URL or checksum is provided — verify the npm package publisher and contents before installing.

Credentials

The skill requests no environment variables or credentials — this is proportionate to public market data. However, if you already have OKX API credentials configured on the machine (CLI config files, environment, or credential helper), the installed CLI could potentially use them. The SKILL.md does not request or read credentials itself.

Persistence & Privilege

The skill does not request permanent presence (always:false) and does not declare system config path access. It simply recommends installing a CLI; it does not instruct the agent to modify other skills or system-wide agent settings.

What to consider before installing

This skill appears to be what it says (public OKX market data), but take these precautions before installing: (1) Verify the npm package scope/name (@okx_ai/okx-trade-cli) on the official npm registry and confirm the publisher is legitimate. (2) Inspect the package (or its repository) for unexpected behavior — especially any code that performs account actions, network exfiltration, or reads local credential files. (3) Prefer installing in a sandboxed environment (container or VM) if you are unsure. (4) If you have OKX API keys or CLI config on your machine, be aware the installed CLI may be able to use them; remove or isolate credentials if you only want read-only market access. (5) Resolve the metadata mismatch (registry said no install spec while SKILL.md contains an install block) — ask the skill author to clarify or provide a canonical install URL or checksum. If the publisher and package are verified and you accept the global-install risk, the skill is functionally coherent.

OKX CEX Market Data CLI

Public market data for OKX exchange: prices, order books, candles, funding rates, open interest, and instrument info. All commands are read-only and do not require API credentials.

Prerequisites

1. Install okx CLI:

   npm install -g @okx_ai/okx-trade-cli
   

2. No credentials needed for market data — all commands are public.
3. Verify install:

   okx market ticker BTC-USDT
   

Demo vs Live Mode

Market data commands are public and read-only — demo mode has no effect. The same data is returned with or without --demo. No confirmation needed before running any market command.

        ↓ decide minPx / maxPx
4. okx-cex-bot       okx bot grid create --instId BTC-USDT ...

Compare perp vs spot premium

User: "Is there a premium between BTC spot and BTC perp?"

1. okx-cex-market    okx market ticker BTC-USDT              → spot last price
2. okx-cex-market    okx market ticker BTC-USDT-SWAP         → perp last price
3. okx-cex-market    okx market mark-price --instType SWAP --instId BTC-USDT-SWAP  → mark price

Discover and price an option

User: "What's the price of a BTC call option expiring this week?"

1. okx-cex-market    okx market open-interest --instType OPTION --instId BTC-USD  → list active option instIds
        ↓ pick target instId from the list (e.g., BTC-USD-250328-95000-C)
2. okx-cex-market    okx market ticker BTC-USD-250328-95000-C → option last price and stats
3. okx-cex-market    okx market orderbook BTC-USD-250328-95000-C → bid/ask spread

Note: okx market instruments --instType OPTION requires --uly <underlying> (e.g., --uly BTC-USD). If the underlying is unknown, use open-interest first to discover active option instIds.

Operation Flow

Step 1: Identify the data needed

• Current price → okx market ticker
• All prices for a category → okx market tickers
• Order book depth → okx market orderbook
• Price history/chart → okx market candles
• Funding cost → okx market funding-rate
• Contract valuation → okx market mark-price or okx market price-limit
• Market volume/OI → okx market open-interest
• What instruments exist → okx market instruments

Step 2: Run commands immediately

All market data commands are read-only — no confirmation needed.

• --instType values: SPOT, SWAP, FUTURES, OPTION
• --bar values: 1m, 3m, 5m, 15m, 30m, 1H, 2H, 4H, 6H, 12H, 1D, 1W, 1M
• --limit: number of results (default varies per endpoint, typically 100)
• --history: for funding-rate, returns historical records instead of current rate

Step 3: No writes — no verification needed

All commands in this skill are read-only. No post-execution verification required.

Input / Output Examples

# → table of all perpetual contracts with last price, 24h high/low/vol

"What's the BTC/USDT order book look like?"

okx market orderbook BTC-USDT
# Asks (price / size):
#          95100.0  2.5
#          95050.0  1.2
# Bids (price / size):
#          95000.0  3.1
#          94950.0  0.8

# → fundingRate: 0.0001 | nextFundingRate: 0.00012 | fundingTime: ... | nextFundingTime: ...

"Show historical funding rates for ETH perp"

okx market funding-rate ETH-USDT-SWAP --history --limit 20
# → table: fundingRate, realizedRate, fundingTime

"What's the open interest on BTC perp?"

okx market open-interest --instType SWAP --instId BTC-USDT-SWAP
# → oi: 125000 | oiCcy: 125000 | ts: ...

Edge Cases

• instId format: SPOT uses BTC-USDT; SWAP uses BTC-USDT-SWAP; FUTURES uses BTC-USDT-250328; OPTION uses BTC-USD-250328-95000-C; Index uses BTC-USD
• OPTION instruments — cannot list directly: okx market instruments --instType OPTION requires --uly BTC-USD (underlying). If the underlying is unknown, run okx market open-interest --instType OPTION first to discover active option instIds from the results, then use those instIds with okx market ticker <instId>
• No data returned: instrument may be delisted or instId is wrong — verify with okx market instruments
• funding-rate: only applies to SWAP instruments; returns error for SPOT/FUTURES
• price-limit: only applies to SWAP and FUTURES instruments
• mark-price: available for SWAP, FUTURES, OPTION; not applicable to SPOT
• candles --bar: use uppercase H, D, W, M for hour/day/week/month (e.g., 1H not 1h)
• index-ticker: use BTC-USD format (not BTC-USDT) for index IDs
• orderbook --sz: max depth is 400; default display shows top 5 per side regardless of --sz

Global Notes

• All market data commands are public — no API key required
• --json returns raw OKX API v5 response for programmatic use
• --profile <name> has no effect on market commands (no auth needed)
• Rate limit: 20 requests per 2 seconds per IP for market data endpoints
• Candle data is sorted newest-first by default
• vol24h in tickers is in base currency (e.g., BTC for BTC-USDT)
