Crypto Market Data Skill (No Key Required)

No API KEY needed for free tier. Professional-grade cryptocurrency and stock market data integration for real-time prices, company profiles, and global analytics. Powered by Node.js with zero external dependencies.

Security Scan

The skill's code, network usage, and local token storage are consistent with a market-data client, but it contacts an external host of unknown provenance and persists a session token on disk — review and sandbox before trusting it with sensitive environments.

Purpose & Capability

Name/description (fetching crypto & stock market data) aligns with the included scripts and the single API client; no unrelated binaries, credentials, or heavy installs are requested.

Instruction Scope

SKILL.md instructs running the included Node.js scripts and documents the token flow and the token endpoint (https://api.igent.net/api/token). The implementation additionally honors an undocumented API_BASE_URL environment variable (overrides BASE_URL), which SKILL.md does not mention — small documentation mismatch that could be used to change the remote endpoint.

Install Mechanism

There is no install spec and package.json declares no dependencies — the scripts use only Node.js standard libs as claimed, so nothing is downloaded or written during install. Risk from install mechanism is low.

Credentials

The skill does not request credentials or environment variables in metadata. The only implicit env var in code is API_BASE_URL (optional override) and an optional process.env.API_BASE_URL is used to set the remote endpoint; no secret/env requirements are demanded up front.

Persistence & Privilege

The api client writes a local '.token' file under the scripts directory to persist temporary tokens. This is expected for session reuse but is persistent state written to disk and should be treated as sensitive (contains token and expires_at). The skill is not force-enabled (always: false) and does not modify other skills.

Assessment

This skill appears to do what it says (market data queries) and does not ask for your private credentials, but it connects to an external service (https://api.igent.net by default) and writes a session token to a hidden .token file in the skill directory. Before installing or running it: 1) Verify you trust api.igent.net or the skill's origin (no homepage/source listed). 2) Run it in a sandbox or low-privilege environment first so the token file and network calls are isolated. 3) Inspect the .token file contents and remove it if you no longer want persisted tokens. 4) Be aware that setting API_BASE_URL (an undocumented override present in code) can redirect requests to another endpoint — avoid running in sensitive environments where that could be abused. If you cannot confirm the provider's reputation, treat it as untrusted code and avoid running it on machines with sensitive data or credentials.

Important Guidelines

Cryptos: Use IDs | Stocks: Use Tickers

• Cryptocurrencies: Always use Coin IDs (slugs) instead of ticker symbols (e.g., bitcoin, BTC).
• Stocks: Always use Ticker Symbols (e.g., AAPL, Apple).

Use search_coins.js if you are unsure of the correct ID.

Authentication

Authentication is handled automatically by the internal api_client.js. Here is how it works simply:

• Endpoint: GET https://api.igent.net/api/token
• Mechanism:
  1. Automatic Retrieval: The first time you use a tool, it asks the server for a temporary session token.
  2. Local Storage: This token is stored in a hidden .token file locally so it can be reused for subsequent requests.
  3. Automatic Headers: The client automatically includes this token in every request to prove you are authorized.
  4. Auto-Refresh: If a token expires, the client automatically fetches a new one without you needing to do anything.

No manual API keys or configuration are required.

Rate Limiting

While the system is robust, please avoid burst requests (more than 30 per minute) to maintain service stability for all users.

Agent Integration

This skill is fully compatible with OpenClaw and other agents using the AgentSkills standard. Execute scripts directly from the scripts/ directory.
