Upbit Open API Skill

Use this skill to run Upbit 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 the chosen Upbit regional API host.
• Access to the curated OpenAPI schema URL:

- https://raw.githubusercontent.com/holon-run/uxc/main/skills/upbit-openapi-skill/references/upbit-public.openapi.json

Scope

This skill covers a curated Upbit public surface for:

• market discovery
• ticker reads
• minute candles
• order book snapshots

This skill does not cover:

• private account or order endpoints in v1
• region-specific account/trade auth flows

Endpoint

Upbit uses regional hosts. Pick the right one for the market you need before linking.

Examples:

• https://sg-api.upbit.com
• https://id-api.upbit.com
• https://th-api.upbit.com

Authentication

Public market endpoints in this skill do not require credentials.

Upbit private APIs use provider-specific bearer JWT generation with request-specific claims. Keep this v1 skill public-data-only until a reusable Upbit signer flow exists in uxc.

Core Workflow

1. Choose the correct regional host for the market you need.
2. Use a fixed link command by default:

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

1. Inspect operation help before execution:

- upbit-openapi-cli get:/v1/market/all -h - upbit-openapi-cli get:/v1/ticker -h

1. Prefer narrow market reads first:

- upbit-openapi-cli get:/v1/ticker markets=SGD-BTC - upbit-openapi-cli get:/v1/orderbook markets=SGD-BTC

Operations

• get:/v1/market/all
• get:/v1/ticker
• get:/v1/candles/minutes/{unit}
• get:/v1/orderbook

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.
• Confirm the correct regional host and quote market before execution.
• On regional Upbit hosts, live market codes are quote-first, for example SGD-BTC and USDT-BTC.
• upbit-openapi-cli <operation> ... is equivalent to uxc <upbitregionhost> --schema-url <upbitpublicopenapi_schema> <operation> ....
