About this skill

ESPN Public API Skill

You are an expert at using ESPN's undocumented public JSON APIs to fetch sports data. These APIs power espn.com and the ESPN mobile app. They require no authentication and return JSON.

Important: These are unofficial, undocumented APIs. They may change without notice. Be respectful with request volume, implement caching when possible, and handle errors gracefully.

How to Use This Skill

  1. Identify what the user needs (scores, standings, player stats, odds, etc.)
  2. Determine the sport and league using the slug reference in references/league-slugs.md
  3. Pick the right API domain and endpoint from references/endpoints.md
  4. Construct the URL and fetch the data
  5. Parse the JSON response using patterns from references/response-schemas.md
  6. Watch for common pitfalls documented in references/gotchas.md

API Domains

There are six ESPN API domains. Choose based on your data need:

Domain Base URL Use For
Site API https://site.api.espn.com/apis/site/v2/sports/{sport}/{league}/ Scores, teams, rosters, news, injuries, game summaries
Site API v2 https://site.api.espn.com/apis/v2/sports/{sport}/{league}/ Standings only (the site/v2 path returns a stub for standings)
Core API v2 https://sports.core.api.espn.com/v2/sports/{sport}/leagues/{league}/ Athletes, detailed stats, odds, play-by-play, venues, coaches
Core API v3 https://sports.core.api.espn.com/v3/sports/{sport}/{league}/ Enriched athlete data, leaders
Web API v3 https://site.web.api.espn.com/apis/common/v3/sports/{sport}/{league}/ Player season stats, gamelogs, splits, leaderboards
CDN https://cdn.espn.com/core/{league-abbrev}/ Full game packages (boxscore + plays + win prob). Requires ?xhr=1
Now API https://now.core.api.espn.com/v1/sports/news Real-time news feed

Quick Start Recipes

Get real-time news

curl "https://now.core.api.espn.com/v1/sports/news?sport=basketball&league=nba&limit=20"

Get full game package via CDN (richest data)

# Returns gamepackageJSON with drives, plays, win probability, boxscore, odds
curl "https://cdn.espn.com/core/nba/game?xhr=1&gameId=401765432"
curl "https://cdn.espn.com/core/nfl/boxscore?xhr=1&gameId=401671793"

Writing Code

When the user wants to write code that calls the ESPN API:

Python (requests or httpx)

import requests

def get_nba_scoreboard(date=None):
    url = "https://site.api.espn.com/apis/site/v2/sports/basketball/nba/scoreboard"
    params = {}
    if date:
        params["dates"] = date  # YYYYMMDD format
    resp = requests.get(url, params=params, timeout=30)
    resp.raise_for_status()
    data = resp.json()
    return data["events"]

JavaScript/TypeScript (fetch)

async function getNBAScoreboard(date?: string) {
  const url = new URL("https://site.api.espn.com/apis/site/v2/sports/basketball/nba/scoreboard");
  if (date) url.searchParams.set("dates", date);
  const resp = await fetch(url.toString());
  if (!resp.ok) throw new Error(`ESPN API error: ${resp.status}`);
  const data = await resp.json();
  return data.events;
}

Best practices for ESPN API code

  • Always set a timeout (30s recommended)
  • Implement caching for data that does not change frequently (teams, standings, rosters)
  • Handle 404s gracefully (invalid IDs, offseason endpoints)
  • Handle 429s (rate limiting) with exponential backoff
  • The API is undocumented, so always validate response shape before accessing nested fields
  • Use User-Agent header to identify your app
