KuCoin OpenAPI Skill

Operate KuCoin public exchange market APIs through UXC with a curated OpenAPI schema, market-first discovery, and explicit private-auth boundary notes.

KuCoin Unified API Skill

Use this skill to run KuCoin public market-data operations through uxc + OpenAPI.

Reuse the uxc skill for shared execution, auth, and error-handling guidance.

Prerequisites

• uxc is installed and available in PATH.
• Network access to https://api.kucoin.com.
• Access to the curated OpenAPI schema URL:
  • https://raw.githubusercontent.com/holon-run/uxc/main/skills/kucoin-openapi-skill/references/kucoin-public.openapi.json

Scope

This skill covers a curated KuCoin public market surface for:

• symbol discovery
• all tickers
• order book snapshots
• candlestick reads

This skill does not cover:

• private account or order endpoints in v1
• websocket, margin, or broader platform products

Authentication

Public market endpoints in this skill do not require credentials.

KuCoin private REST auth uses provider-specific headers and signing rules including passphrase handling. Keep this v1 skill public-data-only until a reusable KuCoin signer flow exists in uxc.

Core Workflow

1. Use the fixed link command by default:

   • command -v kucoin-openapi-cli
   • If missing, create it: uxc link kucoin-openapi-cli https://api.kucoin.com --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/kucoin-openapi-skill/references/kucoin-public.openapi.json
   • kucoin-openapi-cli -h

2. Inspect operation help before execution:

   • kucoin-openapi-cli get:/api/v1/symbols -h
   • kucoin-openapi-cli get:/api/v1/market/allTickers -h

3. Prefer narrow symbol reads first:

   • kucoin-openapi-cli get:/api/v1/market/orderbook/level2_20 symbol=BTC-USDT
   • kucoin-openapi-cli get:/api/v1/market/candles symbol=BTC-USDT type=1hour

Operations

• get:/api/v1/symbols
• get:/api/v1/market/allTickers
• get:/api/v1/market/orderbook/level2_20
• get:/api/v1/market/candles

Guardrails

• Keep automation on the JSON output envelope; do not use --text.
• Parse stable fields first: ok, kind, protocol, data, error.
• Treat this v1 skill as read-only.
• KuCoin symbols use dash-separated names such as BTC-USDT.
• kucoin-openapi-cli <operation> ... is equivalent to uxc https://api.kucoin.com --schema-url <kucoin_public_openapi_schema> <operation> ....
