Dutch volleyball data (Eredivisie, Topdivisie, Superdivisie, and the full Dutch pyramid) via the Nevobo API.

  • Works in 2 steps: Call… → Call…
  • : user asks about Dutch volleyball
  • SKILL.md covers Setup, Quick Start, CRITICAL: Before Any Query and The competition_id Parameter, plus 5 more sections
  • Calls pip and python3

What it does

Volleyball Data is an agent skill from machina-sports/sports-skills. Dutch volleyball data (Eredivisie, Topdivisie, Superdivisie, and the full Dutch pyramid) via the Nevobo API. Standings, schedules, results, clubs, tournaments, and news. Zero config, no API keys. Use when: user asks about Dutch volleyball, Eredivisie volleyball, Nevobo, volleyball standings, volleyball match results, volleyball schedules, or Dutch volleyball clubs. Don't use when: user asks about other sports — use football-data (soccer), nfl-data (NFL), nba-data (NBA), wnba-data (WNBA), nhl-data (NHL), mlb-data…

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/api-reference.md` and `references/competition-ids.md`).

It sits in Data & Analytics. It works with Kalshi, Polymarket and Python. The repository describes itself as: Open-source agent skills for live sports data and prediction markets. Football, F1, Kalshi, Polymarket. Zero API keys. SKILL.md format. The licence is MIT.

When your agent uses it

  • : user asks about Dutch volleyball
  • Eredivisie volleyball
  • Volleyball standings
  • Volleyball match results

Example prompts

  • “/volleyball-data”

Requirements

  • Python 3

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. Call get_standings(competition_id="nevobo-eredivisie-heren") for men
  2. Call get_standings(competition_id="nevobo-eredivisie-dames") for women

What it can do on your machine

Read from SKILL.md and the folder at commit 09eb7e8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • pip
    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Volleyball Data loads about 2k tokens when it runs, and up to ~3.5k if it reads all its reference files. Until then it costs about 190 tokens; SKILL.md has 778 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~190
When it runs · the whole SKILL.md, loaded when a task matches
~2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Volleyball Data (Nevobo — Dutch Volleyball)

Before writing queries, consult references/api-reference.md for endpoints, ID conventions, and data shapes.

Setup

Before first use, check if the CLI is available:

bash
which sports-skills || pip install sports-skills

If pip install fails (package not found or Python version error), install from GitHub:

bash
pip install git+https://github.com/machina-sports/sports-skills.git

The package requires Python 3.10+. If your default Python is older, use a specific version:

bash
python3 --version  # check version
# If < 3.10, try: python3.12 -m pip install sports-skills
# On macOS with Homebrew: /opt/homebrew/bin/python3.12 -m pip install sports-skills

No API keys required. All data comes from the Nevobo (Nederlandse Volleybalbond) open API.

Quick Start

Prefer the CLI — it avoids Python import path issues:

bash
sports-skills volleyball get_competitions
sports-skills volleyball get_standings --competition_id=nevobo-eredivisie-heren
sports-skills volleyball get_results --competition_id=nevobo-eredivisie-dames
sports-skills volleyball get_schedule --competition_id=nevobo-topdivisie-heren-a

Python SDK (alternative):

python
from sports_skills import volleyball

standings = volleyball.get_standings(competition_id="nevobo-eredivisie-heren")
results = volleyball.get_results(competition_id="nevobo-eredivisie-dames")

CRITICAL: Before Any Query

CRITICAL: Before calling any data endpoint, verify:

  • The competition_id uses a valid value from references/competition-ids.md — never guess.
  • For club-specific commands, you have a valid Nevobo club_id (use get_clubs to find one — the organisatiecode field).
  • Do NOT guess club IDs or competition IDs. Use get_competitions or get_clubs to discover them.

The competition_id Parameter

8 leagues across the top 3 tiers of Dutch volleyball are pre-configured. The competition_id follows the pattern nevobo-<league>-<gender>[-<pool>]:

  • Eredivisie (Tier 1, 8 teams): nevobo-eredivisie-heren, nevobo-eredivisie-dames
  • Topdivisie (Tier 2, 10 teams/pool): nevobo-topdivisie-heren-a, nevobo-topdivisie-heren-b, nevobo-topdivisie-dames-a, nevobo-topdivisie-dames-b
  • Superdivisie (Tier 3, 10 teams): nevobo-superdivisie-heren, nevobo-superdivisie-dames

For lower divisions (1e/2e/3e Divisie, regional, youth, beach — 6,400+ poules), use get_poules to discover them.

See references/competition-ids.md for the full reference with team counts and the Dutch volleyball pyramid.

Commands

CommandDescription
get_competitionsList all available competitions and leagues
get_standingsLeague table (rank, team, matches, points)
get_scheduleUpcoming matches (teams, venue, date)
get_resultsMatch results (score, set-by-set scores)
get_clubsList volleyball clubs (name, city, province)
get_club_scheduleClub's upcoming matches across all teams
get_club_resultsClub's results across all teams
get_poulesBrowse Nevobo poules (for lower divisions discovery)
get_tournamentsTournament calendar
get_newsFederation news

See references/api-reference.md for full parameter lists and return shapes.

Current season only. Nevobo removes past-season poules and exports, so get_standings, get_schedule and get_results always cover the current season. Their optional season ("2026-2027" or 2026) returns a clear error for any other season. Matches without a date yet have date: null; cancelled matches carry status: "vervallen".

Examples

Example 1: Eredivisie standings User says: "What are the current Dutch volleyball standings?" Actions:

  1. Call get_standings(competition_id="nevobo-eredivisie-heren") for men
  2. Call get_standings(competition_id="nevobo-eredivisie-dames") for women Result: League tables with rank, team name, matches played, and points

Example 2: Recent match results User says: "Show me recent Eredivisie volleyball results" Actions:

  1. Call get_results(competition_id="nevobo-eredivisie-heren") Result: Match results with home/away teams, match score (e.g. "3-1"), and set scores (e.g. ["25-21", "25-18", "21-25", "25-20"])

Example 3: Club schedule User says: "What matches does LSV have coming up?" Actions:

  1. Call get_clubs(limit=10) and find LSV's organisatiecode (CKL5C67)
  2. Call get_club_schedule(club_id="CKL5C67") Result: Upcoming matches for all of LSV's teams with venues and dates

Example 4: Second tier standings User says: "Show me the Topdivisie standings" Actions:

  1. Call get_standings(competition_id="nevobo-topdivisie-heren-a") for men pool A
  2. Call get_standings(competition_id="nevobo-topdivisie-heren-b") for men pool B Result: Two pool tables with 10 teams each

Example 5: Discover lower divisions User says: "What divisions are available in Dutch volleyball?" Actions:

  1. Call get_poules(regio="nationale-competitie", limit=20) Result: List of national-level poules including 1e/2e/3e Divisie with their abbreviations and descriptions

Commands that DO NOT exist — never call these

  • get_scoreboard — does not exist. Use get_results for recent match results.
  • get_rankings — does not exist. Volleyball uses get_standings for league tables.
  • get_team_roster — does not exist. Use get_clubs for club information.
  • get_player_info — does not exist. Player-level data is not available via this API.

If a command is not listed in the Commands table above, it does not exist.

Error Handling

When a command fails, do not surface raw errors to the user. Instead:

  1. Catch silently and try alternatives
  2. If a club name is given instead of ID, use get_clubs to find the organisatiecode first
  3. If a competition_id returns no data, use get_competitions to verify available leagues
  4. Only report failure with a clean message after exhausting alternatives

Troubleshooting

Error: sports-skills command not found Cause: Package not installed Solution: Run pip install sports-skills. If not on PyPI, install from GitHub: pip install git+https://github.com/machina-sports/sports-skills.git

Error: Standings returns empty list Cause: The competition's regular season phase may have ended, or the season hasn't started yet Solution: Use get_results to check recent results, or get_poules to discover current active poule paths

Error: Schedule returns 0 matches Cause: The competition phase has completed and no more matches are scheduled for that poule Solution: This is expected between season phases. Check other leagues (Topdivisie/Superdivisie may still be active)

Error: Club schedule/results returns error Cause: The club_id may be incorrect Solution: Use get_clubs to find valid club IDs (the organisatiecode field, e.g. "CKL5C67")

Error: Connection errors or timeouts Cause: The Nevobo API may be temporarily unavailable Solution: Wait a moment and retry. The API is public and unauthenticated but may have brief outages
