Kraken REST Skill

Use this skill to run Kraken 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.kraken.com
    .
  • Access to the curated OpenAPI schema URL: 
    • https://raw.githubusercontent.com/holon-run/uxc/main/skills/kraken-openapi-skill/references/kraken-public.openapi.json

Scope

This skill covers a curated Kraken public surface for:
  • server time
  • asset pair metadata
  • ticker reads
  • OHLC candles
  • order book snapshots
This skill does not cover:
  • private account or trade endpoints in v1
  • Kraken FIX
  • broader non-core platform products

Authentication

Public market endpoints in this skill do not require credentials.
Kraken private REST endpoints use provider-specific header signing and nonce handling. Keep this v1 skill public-data-only until a reusable Kraken signer flow exists in 
uxc
.

Core Workflow

  1. Use the fixed link command by default:
    • command -v kraken-openapi-cli
    • If missing, create it: 
      uxc link kraken-openapi-cli https://api.kraken.com --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/kraken-openapi-skill/references/kraken-public.openapi.json
    • kraken-openapi-cli -h
  2. Inspect operation help before execution:
    • kraken-openapi-cli get:/0/public/Time -h
    • kraken-openapi-cli get:/0/public/Ticker -h
  3. Prefer narrow pair reads first:
    • kraken-openapi-cli get:/0/public/Ticker pair=XBTUSD
    • kraken-openapi-cli get:/0/public/Depth pair=XBTUSD count=20

Operations

  • get:/0/public/Time
  • get:/0/public/AssetPairs
  • get:/0/public/Ticker
  • get:/0/public/OHLC
  • get:/0/public/Depth

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.
  • Kraken pair naming can differ from other venues. Check 
    AssetPairs
    before assuming symbol strings.
  • kraken-openapi-cli <operation> ...
    is equivalent to 
    uxc https://api.kraken.com --schema-url <kraken_public_openapi_schema> <operation> ...
    .
