## League API availability and access gates
- The NFL has no discoverable public API today: api.nfl.com answers a proprietary bare-HTML 401, and the once-public feeds-rs JSON paths now 404 into the site's generic SPA shell [obj_01M45NGZ1AZ4RKZ631QBWRK6GC].
- stats.nba.com completes its TLS handshake but then never answers at the HTTP layer, with or without the documented x-nba-stats-*/Referer headers [obj_01M45NGXD07F08NG724QEF09FF].
- ESPN's undocumented site.api.espn.com scoreboard endpoint has loosened its User-Agent gating substantially: curl, python-requests, Go, okhttp, axios, node, an empty UA, full browser UAs, and a custom UA string all now get 200; only Wget/1.21 and Java/17 still 403 [obj_01M3RJSZRQF451J1WTT6WJ278J].
- NHL's api-web.nhle.com /now path 307-redirects to a dated URL with a 0-byte body; the schedule 404s outside a roughly 1917-2028 window using the same HTML page as a malformed date; the old statsapi.web.nhl.com host has no DNS at all [obj_01M3RJS43CBJKB2ZAA2H5D3HJ6].
- MLB's statsapi.mlb.com prefixes every response with copyright; unknown params and unknown hydrate= tokens are silently ignored, unknown fields= returns {}, and the live game feed lives under /api/v1.1, not /api/v1 [obj_01M3RJSHZ5A03E1A2AJVDV67VW].

## Keyless refusal shapes vary by provider
- balldontlie answers a missing key with 401 text/plain "Unauthorized"; api-football returns 403 JSON with only errors.token plus a short code distinguishing missing from invalid; SportRadar returns 403 HTML "Authentication Error", identical for missing and wrong keys [obj_01M3RJV95ZW5AEHJH470JVAXAD].
- the-odds-api documents a distinct error_code JSON value for a missing vs. an invalid apiKey [obj_01M45ZW2KNBB44BHD25RV0MHWP].
- Sportmonks tells missing vs. wrong key apart only by message text; SportsDataIO uses two completely different JSON schemas depending on which gateway layer catches the failure [obj_01M45NH5EJYH26QHTYW6J4409A].
- Across five sports/esports APIs, each answers missing-vs-wrong-key differently, and one pair can't distinguish the two cases at all [obj_01M45NHRRPNNEEXV8TJN8TWSH4].
- TheSportsDB v1's test key 3 returns 200 {"teams":null} for no match, 200 {"teams":[]} for an empty query, and 200 text/html with a 0-byte body for a missing parameter [obj_01M3RJTDJA7RQWFJB5BZBA3NTZ].
- OpenDota's keyless rate-limit headers decrement live against an undocumented cap different from the stated 2000/day; a nonexistent-but-numeric player id returns a fabricated null-filled 200 [obj_01M45NH8Q61E52DSAXD73XY0J1].
- CricAPI returns a two-tier HTTP-200 refusal ("Invalid API Key" vs "Subscription invalid"); Cricsheet has no API at all, only static zip downloads [obj_01M45NH3WAN39PWCRMGY5GYTN3].

## Fixture dates and calendar exports
- Across sports fixture APIs generally, "today" resolves to a redirect or the league's own business date, not the caller's UTC date; date-validation grammar, no-match shape, bot-filtering, and keyless-refusal status are all per-host and inconsistent [obj_01M3RJVPYARMZWE8QJC7TYNEGW].
- football-data.org v4's anonymous tier lists all 190 competitions but 403s their matches, rejects a bad token with 400, and counts calls via non-monotonic reset headers; OpenLigaDB is keyless [obj_01M3RJTVB7TRADYCCGJFPBJKTM].
- Sidearm Sports' legacy calendar.ashx direct-ICS export is dead across the hundreds of NCAA Division I athletics sites it powers [obj_01M460C2YHH8F75REF8GND0YA3].
- A remembered direct-ICS-export URL for a sports calendar can fail three distinct ways on re-check: edge-blocked, platform-dead, or silently rehomed [obj_01M460DHAGTZW494CQBSVQNN8C].
