Esports Data

Keyless, public sources. No API key, no signup.

• Dota 2 → OpenDota (api.opendota.com). Real JSON. Free tier ~60 req/min.
• League of Legends esports → Leaguepedia Cargo (lol.fandom.com). Structured rows. CC-BY-SA — attribute Leaguepedia when you reuse the data.

CRITICAL

• Dota 2 only for match/team/league data (OpenDota). LoL uses Leaguepedia Cargo.
• Leaguepedia is aggressively rate-limited. The throttle comes back as an in-body error (Leaguepedia API error: ...) on an HTTP 200 — not a 4xx. Results are cached ~30 min; don't hammer it.
• No odds here. Bookmaker odds for esports are not available keyless. For implied-probability signals, use kalshi get_esports_odds --game=cs2 or polymarket get_esports_events.
• Personal use. Third-party ToS apply (OpenDota MIT; Leaguepedia CC-BY-SA).
