Dota 2 Verified Sep 2026
OpenDota provides open Dota 2 match, player, and hero statistics parsed from Valve's WebAPI and replay files, including hero win rates, benchmarked performance percentiles, and full match/player history. The core API is entirely keyless and free, with a 60-call-per-minute / 3,000-call-per-day limit; registering a free account for an API key only raises those limits, it doesn't gate access.
OpenDota provides open Dota 2 match, player, and hero statistics parsed from Valve's WebAPI. A live GET this run against /players/1 returned a genuine 837 B player profile at HTTP 200, content-type: application/json; charset=utf-8 — fully keyless.

Auth quickstart No API key, signup, or credit card required — the live GET above returned real player data with no auth header attached. An optional free API key only raises the rate limit; it never gates access. A keyless request this run carried x-rate-limit-remaining-minute: 57 and x-rate-limit-remaining-day: 2987, consistent with the documented 60/minute, 3,000/day keyless ceiling. Stored key No key stored Clear key
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.

Developer reference Base URL https://api.opendota.com/api
Rate limit 60 requests/minute and 3,000 requests/day per IP, unauthenticated (an API key raises the limit) -- live x-rate-limit-remaining-minute/x-rate-limit-remaining-day headers on api.opendota.com/api/status.
Key endpoints GET /players/{account_id} GET /heroStats GET /heroes GET /matches/{match_id} Gotchas & limits CORS echoes the caller's Origin instead of a wildcard — a live GET this run with Origin: https://greatapis.com returned access-control-allow-origin: https://greatapis.com, access-control-allow-credentials: true, and vary: Origin; the same GET with no Origin header carried no access-control-allow-origin at all (though access-control-allow-credentials: true was still present either way). A bare curl with no Origin showing no ACAO is expected behavior, not an outage. Rate-limit headers use a non-standard hyphenation — a live GET this run returned x-rate-limit-remaining-minute and x-rate-limit-remaining-day (not the conventional x-ratelimit-* spelling), and there is no x-rate-limit-limit and no retry-after header. The only way to infer the ceiling is by watching the remaining count decrement across calls. Unknown IDs return a clean 404, not an empty or malformed body — live GETs this run against both /players/999999999 and /matches/1 returned HTTP 404 with the identical 21 B body {"error":"Not Found"}. A valid low account ID still resolves normally, confirmed live above with /players/1 — a small numeric ID is not itself a sign of an invalid one. /players/{account_id} takes the 32-bit Dota account ID, not the 64-bit Steam ID — confirmed live above: the same profile carries account_id: 1 and steamid: "76561197960265729" side by side, and only the former works in the path.The free tier is not a trial — a live keyless GET this run to /heroStats (164,790 B) and /heroes (21,804 B) both returned full HTTP 200 datasets with no key, no truncation, and no upsell fields; registering a key only raises the 60/min, 3,000/day ceiling reported in the rate-limit headers above, it doesn't unlock additional data.
