Alpha Vantage API

Alpha Vantage 金融数据 API。支持股票、外汇、加密货币的实时和历史数据。 免费 API key: demo (限流)，建议申请自己的免费 key。

Security Scan

This skill is an on-disk Node.js client for the Alpha Vantage API and its requirements and behavior are consistent with that purpose, though it persists the API key to a local config file and the SKILL.md has minor doc mismatches.

Purpose & Capability

Name/description match the included code: alpha.js implements calls to alphavantage.co for quotes, time series, forex and crypto. No unrelated network endpoints, binaries, or credentials are requested.

Instruction Scope

SKILL.md instructs running node alpha.js and shows expected commands, which align with the code. Minor mismatches: SKILL.md examples sometimes use 'alpha quote AAPL' and show using an ALPHA_KEY environment var, but alpha.js does not read ALPHA_KEY and expects commands invoked as 'node alpha.js ...' or via stored config. This is a documentation inconsistency but not malicious scope creep.

Install Mechanism

No install spec; skill is instruction+script only (alpha.js). Nothing is downloaded or extracted at install time.

Credentials

The skill does not require environment variables or external credentials up front. It does persist an API key to a local config.json (in the skill directory) when you run 'apikey', which is expected for this client but means your key is stored on disk in plaintext.

Persistence & Privilege

always:false (no forced presence). The script writes its own config.json in its directory to store the API key, which is normal for a CLI client and does not modify other skills or system-wide settings.

Assessment

This skill appears to do what it claims: it calls alphavantage.co and stores a provided API key in a local config.json. Before installing, consider: (1) the package author/source is unknown and there is no homepage — review the code if you don't trust the origin; (2) the API key is saved in plaintext to config.json in the skill directory—ensure that directory's permissions are acceptable or avoid storing sensitive/prod keys there; (3) SKILL.md mentions an ALPHA_KEY env var and shorter command names that the script doesn't actually use—follow the script's documented usage (node alpha.js ...) or inspect/adjust the code if you want env-var support; (4) prefer creating a dedicated Alpha Vantage key with limited permissions/usage and monitor usage for unexpected requests.
