What it does

Coinbase Openapi Skill is an agent skill from holon-run/uxc. Operate Coinbase Advanced Trade REST APIs through UXC with a curated OpenAPI schema, products-first discovery, and explicit JWT bearer auth guidance.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/coinbase-advanced-trade.openapi.json` and `references/usage-patterns.md`).

It sits in Backend & APIs, covering OpenAPI specifications, Authentication and REST APIs. It works with Coinbase and OpenAPI. The repository describes itself as: A unified CLI for discovering and invoking tools across OpenAPI, MCP, GraphQL, gRPC, and JSON-RPC. The licence is MIT.

When your agent uses it

Tasks that involve OpenAPI specifications
Tasks that involve Authentication
Tasks that involve REST APIs

Example prompts

“/coinbase-openapi-skill”

Requirements

A Bash shell
A credential in COINBASE_PRIVATE_KEY

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

Download or copy the Coinbase API key material
Store those values in a local credential.
Bind the credential to api.coinbase.com with a jwt_bearer_v1 signer.

What it can do on your machine

Read from SKILL.md and the folder at commit 562d47c. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Shell), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- api.coinbase.com
Also links to:
- docs.cdp.coinbase.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- COINBASE_KEY_ID
- COINBASE_PRIVATE_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Coinbase Openapi Skill loads about 1.3k tokens when it runs, and up to ~3.3k if it reads all its reference files. Until then it costs about 43 tokens; SKILL.md has 399 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~43
When it runs · the whole SKILL.md, loaded when a task matches: ~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~3.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Coinbase Advanced Trade Skill

Use this skill to run Coinbase Advanced Trade REST 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.coinbase.com.
Access to the curated OpenAPI schema URL:
- https://raw.githubusercontent.com/holon-run/uxc/main/skills/coinbase-openapi-skill/references/coinbase-advanced-trade.openapi.json

Scope

This skill covers a curated Coinbase Advanced Trade surface for:

product and best-bid-ask market reads
account summary reads
order create, cancel, and lookup workflows

This skill does not cover:

Coinbase Exchange APIs
Coinbase Prime APIs
Coinbase Derivatives APIs
wallet or retail app product families outside Advanced Trade

Authentication

Public product endpoints can be read without credentials.

Private account and order endpoints require a Coinbase Advanced Trade bearer JWT. uxc now supports Coinbase's request-scoped JWT flow directly through jwt_bearer_v1, so you can store the API key id and private key in a credential and let uxc mint the short-lived bearer token per request.

Recommended v1 setup:

Download or copy the Coinbase API key material:
- key_id: organizations/{org_id}/apiKeys/{key_id}
- private_key: Coinbase exports either -----BEGIN EC PRIVATE KEY----- or -----BEGIN PRIVATE KEY-----; uxc accepts both PEM forms for ES256.
Store those values in a local credential.
Bind the credential to api.coinbase.com with a jwt_bearer_v1 signer.

bash

uxc auth credential set coinbase-advanced-trade \
  --auth-type api_key \
  --field key_id=env:COINBASE_KEY_ID \
  --field private_key=env:COINBASE_PRIVATE_KEY

uxc auth binding add \
  --id coinbase-advanced-trade \
  --host api.coinbase.com \
  --path-prefix /api/v3/brokerage \
  --scheme https \
  --credential coinbase-advanced-trade \
  --signer-json '{"kind":"jwt_bearer_v1","algorithm":"es256","private_key_field":"private_key","header_typ":"JWT","header_kid_field":"key_id","expires_in_seconds":120,"claims":{"static":{"iss":"cdp"},"from_fields":{"sub":"key_id"},"time":{"nbf":"now","exp":"now_plus_ttl"}},"request_claim":{"name":"uri","format":"string","value_template":"{{request.method}} {{request.host}}{{request.path}}"}}' \
  --priority 100

Validate the active mapping when auth looks wrong:

bash

uxc auth binding match https://api.coinbase.com/api/v3/brokerage/accounts

Core Workflow

Use the fixed link command by default:
- command -v coinbase-openapi-cli
- If missing, create it: uxc link coinbase-openapi-cli https://api.coinbase.com --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/coinbase-openapi-skill/references/coinbase-advanced-trade.openapi.json
- coinbase-openapi-cli -h
Inspect operation help before execution:
- coinbase-openapi-cli get:/api/v3/brokerage/products -h
- coinbase-openapi-cli get:/api/v3/brokerage/accounts -h
- coinbase-openapi-cli post:/api/v3/brokerage/orders -h
Prefer product reads before private account or order workflows:
- coinbase-openapi-cli get:/api/v3/brokerage/products product_type=SPOT limit=20
- coinbase-openapi-cli get:/api/v3/brokerage/best_bid_ask product_ids=BTC-USD,ETH-USD
Treat all order placement and cancellation as high-risk writes.

Operations

get:/api/v3/brokerage/products
get:/api/v3/brokerage/products/{product_id}
get:/api/v3/brokerage/best_bid_ask
get:/api/v3/brokerage/accounts
get:/api/v3/brokerage/accounts/{account_uuid}
post:/api/v3/brokerage/orders
post:/api/v3/brokerage/orders/batch_cancel
get:/api/v3/brokerage/orders/historical/{order_id}
get:/api/v3/brokerage/orders/historical/batch

Guardrails

Keep automation on the JSON output envelope; do not use --text.
Parse stable fields first: ok, kind, protocol, data, error.
uxc mints a fresh short-lived Coinbase JWT on each private request; do not try to bind a stale pre-generated bearer token when jwt_bearer_v1 is available.
Coinbase exports ES256 private keys in more than one PEM form; this skill expects the raw downloaded PEM and does not require a manual PKCS#8 conversion step.
Treat post:/api/v3/brokerage/orders and post:/api/v3/brokerage/orders/batch_cancel as high-risk writes.
Keep initial product/account pulls narrow with small limit values.
coinbase-openapi-cli <operation> ... is equivalent to uxc https://api.coinbase.com --schema-url <coinbase_advanced_trade_openapi_schema> <operation> ....
