What it does
Coinapi Openapi Skill is an agent skill from holon-run/uxc. Operate CoinAPI market data reads through UXC with a curated OpenAPI schema, API-key auth, and read-first guardrails.
Its SKILL.md is about 880 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/coinapi-market.openapi.json` and `references/usage-patterns.md`).
It sits in Backend & APIs, covering OpenAPI specifications and Stock and market analysis. It works with OpenAPI and Binance. 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 Stock and market analysis
Example prompts
- “/coinapi-openapi-skill”
Requirements
- A Bash shell
- A credential in COINAPI_KEY
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Use the fixed link command by default
- Inspect operation schema first
- Prefer narrow spot and latest reads before broader crawls
- Execute with key/value parameters
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:
rest.coinapi.io
Also links to:
docs.coinapi.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
COINAPI_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Coinapi Openapi Skill loads about 881 tokens when it runs, and up to ~2.6k if it reads all its reference files. Until then it costs about 35 tokens; SKILL.md has 261 words of instructions outside code blocks.
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.

- Operate CoinAPI market data reads through UXC with a curated OpenAPI schema, API-key auth, and read-first guardrails.
CoinAPI REST Skill
Use this skill to run CoinAPI REST market data operations through uxc + OpenAPI.
Reuse the uxc skill for shared execution, auth, and error-handling guidance.
Prerequisites
uxcis installed and available inPATH.- Network access to
https://rest.coinapi.io. - Access to the curated OpenAPI schema URL:
https://raw.githubusercontent.com/holon-run/uxc/main/skills/coinapi-openapi-skill/references/coinapi-market.openapi.json
- A CoinAPI key.
Scope
This skill covers a read-first market data surface:
- current exchange rates
- current quote snapshots
- latest OHLCV candles
- latest trades
- latest order books
This skill does not cover:
- FIX, WebSocket, or MCP transport surfaces
- write operations
- the broader CoinAPI catalog
Authentication
CoinAPI uses X-CoinAPI-Key header auth.
Configure one API-key credential and bind it to rest.coinapi.io:
uxc auth credential set coinapi \
--auth-type api_key \
--api-key-header X-CoinAPI-Key \
--secret-env COINAPI_KEY
uxc auth binding add \
--id coinapi \
--host rest.coinapi.io \
--scheme https \
--credential coinapi \
--priority 100Validate the active mapping when auth looks wrong:
uxc auth binding match https://rest.coinapi.ioCore Workflow
Use the fixed link command by default:
command -v coinapi-openapi-cli- If missing, create it:
uxc link coinapi-openapi-cli https://rest.coinapi.io --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/coinapi-openapi-skill/references/coinapi-market.openapi.json coinapi-openapi-cli -h
Inspect operation schema first:
coinapi-openapi-cli get:/v1/exchangerate/{asset_id_base}/{asset_id_quote} -hcoinapi-openapi-cli get:/v1/ohlcv/{symbol_id}/latest -hcoinapi-openapi-cli get:/v1/trades/{symbol_id}/latest -h
Prefer narrow spot and latest reads before broader crawls:
coinapi-openapi-cli get:/v1/exchangerate/{asset_id_base}/{asset_id_quote} asset_id_base=BTC asset_id_quote=USDcoinapi-openapi-cli get:/v1/quotes/current filter_symbol_id=BINANCE_SPOT_BTC_USDT
Execute with key/value parameters:
coinapi-openapi-cli get:/v1/ohlcv/{symbol_id}/latest symbol_id=BINANCE_SPOT_BTC_USDT period_id=1DAY limit=10coinapi-openapi-cli get:/v1/orderbooks/{symbol_id}/latest symbol_id=BINANCE_SPOT_BTC_USDT limit_levels=20

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. Do not imply order entry or market connectivity support.
- Keep
filter_symbol_id,period_id,limit, andlimit_levelsnarrow unless the user explicitly wants larger pulls. coinapi-openapi-cli <operation> ...is equivalent touxc https://rest.coinapi.io --schema-url <coinapi_openapi_schema> <operation> ....
