Repository

Install on your platform

This skill no longer installs under the name market-data. SKILL.md has no name/description frontmatter, so the skills CLI skips it.

We check each listing against its upstream repository with the rules the skills CLI uses, last on 2026-09-29. We don't show a command we know will fail.

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 2 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • Declares what it does: failed

    SKILL.md has no YAML frontmatter, so it declares nothing machine-readable.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: failed

    Contacts 2 hosts that are neither well-known infrastructure nor declared in the skill's frontmatter: api.eng0.ai, mcp.xyznot.com.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

About this skill

What it does

This skill provides access to real-time US stock market data through eng0's data proxy service. It allows agents to retrieve historical price bars (OHLCV), financial news with sentiment analysis, and company details including market capitalization for US stock tickers. The data is sourced from a 15-minute delayed quotes feed covering all US stocks and spanning the last five years.

When to use it

  • Investment Research: Quickly gather historical price data (e.g., daily or weekly bars) to analyze trends and patterns.
  • News Monitoring: Stay informed about recent news articles related to specific companies, including sentiment analysis to gauge market perception.
  • Company Overview: Obtain key company information like market capitalization for due diligence or portfolio tracking.
  • Automated Trading Strategies: Integrate with automated trading systems that require real-time data feeds (note: 15-minute delay).

Key capabilities

  • Retrieval of OHLCV price bars (1-minute to 1-week intervals)
  • Access to financial news articles with sentiment analysis (positive, negative, or neutral)
  • Company details including market capitalization
  • API schema discovery via the /schema endpoint.
  • Data coverage for all US stock tickers with five years of historical data.

Example prompts

  • "Get me the daily price bars for AAPL from January 1st, 2024 to December 31st, 2024."
  • "What are the latest 5 news articles about TSLA and what is their sentiment?"
  • "Can you retrieve company details for AAPL?"

Tips & gotchas

  • The data provided is subject to a 15-minute delay. This skill is not suitable for applications requiring real-time, tick-by-tick data.
  • Ensure the ticker symbol used in prompts is valid and accurate (e.g., AAPL, MSFT).
  • When requesting news articles, the limit parameter defaults to 10 and has a maximum value of 100.
