Quick Start
Base URLs: see references/base-urls.md
TypeScript helper:
CONSTRAINT: You MUST copy the
fetchSignedfunction below verbatim when generating code. Do NOT rewrite the signing, request, or JSON parsing logic. Only modify: (1)BASEURL entries for custom environments, (2) business parameters passed tofetchSigned. For the full client with URL-encoding and JSON body support, seereferences/authentication.md.
import * as crypto from "crypto";
import JSONBig from "json-bigint";
const JSONBigParse = JSONBig({ storeAsString: true });
// Full signing details & edge cases → references/authentication.md
// Domain priority: .com is mandatory primary; .pro is fallback for network/timeout errors ONLY.

Code Usage Rules
- MUST copy
fetchSignedverbatim -- do not simplify or rewrite - MUST use
json-bigint(JSONBigParse.parse) for response parsing -- notJSON.parse - MUST include
X-SOURCE-KEY: BX-AI-SKILLheader on every request - MUST NOT remove the domain fallback loop or
isNetworkOrTimeoutcheck
Common Calls
24h ticker price for BTC-USDT:
const ticker = await fetchSigned("prod-live", API_KEY, SECRET, "GET",
"/openApi/swap/v2/quote/ticker", { symbol: "BTC-USDT" }
);
// ticker.lastPrice, ticker.priceChangePercent, ticker.volume
Order book depth (top 20 levels):
const depth = await fetchSigned("prod-live", API_KEY, SECRET, "GET",
"/openApi/swap/v2/quote/depth", { symbol: "BTC-USDT", limit: 20 }
);
// depth.bids: [price, qty][], depth.asks: [price, qty][]
1-hour klines (last 100 candles):
const klines = await fetchSigned("prod-live", API_KEY, SECRET, "GET",
"/openApi/swap/v3/quote/klines", { symbol: "BTC-USDT", interval: "1h", limit: 100 }
);
// Each item: [openTime, open, high, low, close, volume, closeTime]
Current funding rate:
const funding = await fetchSigned("prod-live", API_KEY, SECRET, "GET",
"/openApi/swap/v2/quote/fundingRate", { symbol: "BTC-USDT" }
);
// funding.fundingRate, funding.nextFundingTime
Best bid/ask price:
const bookTicker = await fetchSigned("prod-live", API_KEY, SECRET, "GET",
"/openApi/swap/v2/quote/bookTicker", { symbol: "BTC-USDT" }
);
// bookTicker.bidPrice, bookTicker.askPrice

Agent Interaction Rules
swap-market provides read-only market data. All requests require timestamp + HMAC SHA256 signature + X-BX-APIKEY header (no special API KEY permission needed). No CONFIRM needed. The interaction goal is to collect query parameters.
Operation Identification
When the user's request is vague (e.g. "check the market" or "look at BTC"), first identify what type of data they want to query:
Please select the market data type:
- Price / 24h change — ticker
- Best bid/ask price (top of book) — bookTicker
- Order book depth — depth
- K-lines / Candlesticks — klines
- Funding rate — fundingRate
- Mark price / Premium index — premiumIndex
- Open interest — openInterest
- Contract specification list — contracts
When symbol is missing
Applicable endpoints: depth, trades, fundingRate, klines, openInterest
Please select a trading pair (or type another):
- BTC-USDT
- ETH-USDT
- SOL-USDT
- BNB-USDT
- Other (enter manually, format: BASE-USDT)
If the trading pair can be inferred from context (e.g. "BTC market today" or "Ethereum funding rate"), infer it automatically without asking again.
When interval is missing (klines endpoint only)
Please select a K-line interval:
- 1m (1 minute)
- 5m (5 minutes)
- 15m (15 minutes)
- 1h (1 hour)
- 4h (4 hours)
- 1d (daily)
- 1w (weekly)
limit handling
- klines: default 100, no need to ask — inform the user "returning the most recent 100 K-lines by default"
- depth: default 20, no need to ask
Endpoints where symbol is optional
symbol is optional for ticker and premiumIndex (returns all contracts if omitted). bookTicker requires symbol. If the user does not specify a trading pair for ticker/premiumIndex, query all contracts and inform the user; if a trading pair is specified, query only that pair.
