CoinGlass API SKILL

CoinGlass API skill. Routes to the appropriate sub-skill based on user intent. Covers futures, ETF, options, spots, on-chain, indicators, account, and other...

Security Scan

The skill appears to be a documentation/adapter for the CoinGlass API and mostly matches its stated purpose, but its runtime instructions and API examples assume an API key (CG-API-KEY) while the skill declares no required credential or environment variable — an incoherence you should understand before installing.

Purpose & Capability

Name and description (crypto market data across futures, spots, ETF, on-chain, etc.) match the provided API.md files and routing table. Requiring curl is reasonable for an instruction-only wrapper that runs HTTP requests.

Instruction Scope

The SKILL.md and per-endpoint API.md files instruct the agent to call CoinGlass endpoints via curl and include a CG-API-KEY header in examples (e.g. CG-API-KEY: ${YOUR_API_KEY}). The skill's root instructions tell the agent to read the sub-skill API.md files and follow them. There are no instructions to read local files, system configs, or unrelated environment variables, but the explicit use of ${YOUR_API_KEY} in many examples implies the agent will need an API key even though none is declared.

Install Mechanism

Instruction-only skill with no install spec and no code files — no files are written to disk and nothing is downloaded or executed beyond curl-initiated HTTP requests.

Credentials

Many API examples expect a CG-API-KEY header (placeholder ${YOUR_API_KEY}) but the registry metadata lists no required environment variables or primary credential. That mismatch is an incoherence: the skill will function only if an API key is provided, but it doesn't declare how the platform will receive/store that key. This omission increases risk of accidental key exposure if users paste keys into chat or otherwise supply them insecurely.

Persistence & Privilege

always is false and the skill is user-invocable with normal autonomous invocation allowed. There is no install or behavior that attempts to modify other skills or system configuration.

What to consider before installing

This skill is a documentation-style wrapper around the CoinGlass REST API and will make HTTP requests to open-api-v4.coinglass.com using curl. Before installing: 1) Expect to need a CoinGlass API key — the API docs show a CG-API-KEY header, but the skill does not declare any required env var or primary credential; confirm how you will provide the key on this platform. 2) Only provide a read-only / limited-scope API key (if possible); do not paste high-privilege or account-management keys into chat. 3) Verify the skill's source (the homepage points to a GitHub repo) and confirm it's the official integration. 4) Review which endpoints you will call — most examples are GET/read-only, but avoid supplying API keys with write/trade permissions. 5) If you need stronger assurances, ask the publisher to update the skill metadata to declare a required environment variable for the API key (so the platform handles it securely) and to document expected key scope.

This is the root entry point for all CoinGlass API skills. It provides access to comprehensive crypto market data including futures, ETF flows, options, spot markets, on-chain data, indicators, and account information.

When a user request matches a sub-skill, read the corresponding API.md for that sub-skill and follow its instructions.
