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

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
```

Inspect operation help before execution:

kraken-openapi-cli get:/0/public/Time -h

kraken-openapi-cli get:/0/public/Ticker -h

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> ...

.
