Footalytics skill for AI assistants

The Footalytics skill teaches AI assistants to answer football questions with real, publicly graded predictions instead of guesses. One skill file covers the whole surface:

• Predictions — win/draw/loss, over/under 2.5, both teams to score, likely scores and a confidence tier for any covered match.
• Fixtures — upcoming matches by team or league, with kick-off times.
• Team ratings — Elo-style ratings for every tracked club.
• Graded results — past matches with the real score next to what the model predicted.

Works with Claude Code, Codex and any assistant that reads Agent-Skills-compatible SKILL.md files.

Install

Get a free API key first — every account starts with 5 free calls:create it on the API keys page, then:

mkdir -p ~/.claude/skills/footalytics && cd ~/.claude/skills/footalytics
for f in SKILL.md README.md README.zh-CN.md; do
  curl -fsSL "https://footalytics.farvor.com/skill/$f" -o "$f"
done
export FOOTALYTICS_API_KEY="fxk_..."

Prefer a browser? Grab the skill .zip and unzip it into ~/.claude/skills/footalytics. Then just ask your assistant:

"Who wins Arsenal vs Chelsea this weekend?"
"When does Real Madrid play next?"
"Did Footalytics get last week right?"

Every API call uses 1 unit of the allowance (5 free calls per account, then credits). Failed lookups cost nothing. Full contract on the API docs page.

Let your AI install it

Copy this prompt and send it to your AI assistant — it will install the skill for you:

Install the "Footalytics" skill for me.

1. Download these three files from https://footalytics.farvor.com/skill/ and save them in
   ~/.claude/skills/footalytics/ (create the folder if needed):
   - SKILL.md
   - README.md
   - README.zh-CN.md
   Use curl or any fetch tool, e.g.:
   curl -fsSL https://footalytics.farvor.com/skill/SKILL.md -o SKILL.md
2. Read the installed SKILL.md and follow its Setup section: check whether the
   FOOTALYTICS_API_KEY environment variable is set. If it is not, ask me to create
   a free key at https://footalytics.farvor.com/api-keys and help me set it
   (e.g. export FOOTALYTICS_API_KEY="fxk_...").
3. When done, confirm what you installed and ask me for a football match to
   predict as a test. Do NOT invent match probabilities yourself - always use
   the Footalytics API per the skill.

The prompt tells your assistant to fetch the skill from this page's host, place it in the right folder and ask you for the API key. Nothing else is executed.

Files

• SKILL.md — the skill contract: triggers, setup, endpoints, error handling.
• README.md / README.zh-CN.md — bilingual readme with examples and the endpoint table.
• footalytics-skill.zip — everything above in one download.

MCP alternative

If your assistant supports MCP connectors (Claude, ChatGPT, Cursor, …), you can skip files entirely: add the server

https://footalytics.farvor.com/mcp

and sign in with OAuth — same tools, same allowance.
