Odds endpoints mix unrelated outcomes into a single event response (event 318)

Summary For Crystal Palace vs Newcastle United (event 318), the odds responses contain outcomes from completely different matches (for example Cesena, Reggiana, Padova, Catanzaro, Virtus Entella), even though event_info.id is 318. This causes wrong bookmaker 1X2 prices for the target match. Environment API base: https://sports.bzzoiro.com/api Timestamp of reproduction: 2026-04-12T13:08:50Z Auth: Token auth Target event: 318 (Crystal Palace vs Newcastle United) Reproduction Steps Call GET https://sports.bzzoiro.com/api/events/318/ Call GET https://sports.bzzoiro.com/api/odds/compare/?event=318 Call GET https://sports.bzzoiro.com/api/odds/?event=318&market=1x2&page_size=50 Expected Only outcomes for this match should appear in 1x2: Crystal Palace Draw Newcastle (or Newcastle United) Bookmaker prices should correspond to this exact event. Actual Compare endpoint returns foreign team outcomes in 1x2: 1x2 keys count: 13 Foreign outcomes include: Virtus Entella, Empoli, Reggiana, Padova, Catanzaro, Juve Stabia, Cesena, Palermo Raw odds endpoint also contains foreign outcomes while event_info is still event 318: Example rows from GET /api/odds/?event=318&market=1x2 outcome_name: Cesena, bookmaker: Eurobet, decimal_odds: 5.2, event_info.id: 318 outcome_name: Virtus Entella, bookmaker: Stake Sport Italia, decimal_odds: 3.8, event_info.id: 318 outcome_name: Reggiana, bookmaker: Bwin Italia, decimal_odds: 3.6, event_info.id: 318 outcome_name: Catanzaro, bookmaker: AdmiralBet, decimal_odds: 3.25, event_info.id: 318 Event-level odds from event detail look coherent: GET /api/events/318/ odds_home: 2.9 odds_draw: 3.25 odds_away: 2.4 But compare/bookmaker values for Bwin Spain are very different: Crystal Palace: 2.00 Draw: 2.25 Newcastle: 1.71 User impact Incorrect bookmaker lines are shown for 1X2. End users see odds that do not match bookmaker websites. Any app relying on compare or raw event-filtered odds may display wrong data.

Resolution: Fixed block-based market parser: 1x2 balanced, BTTS unified, O/U standalone

Woops not a feature but a bug.

Hola Bashernoob, Yes, you're right — this is a bug, not a feature request. Good catch on the correction! What you're describing is a real problem: foreign outcome names (Cesena, Reggiana, Virtus Entella, etc.) leaking into the odds for event 318 (Crystal Palace vs Newcastle United). These look like Serie B teams, which have nothing to do with a Premier League match. This suggests an odds ingestion issue — likely a mapping collision where odds rows from a different match got assigned to event_id 318. The fact that /events/318/ shows coherent top-level odds (2.9 / 3.25 / 2.4) but /odds/?event=318 returns Italian team names points to a data linkage problem at the bookmaker-outcome level, not the event itself. I'm escalating this for investigation. In the meantime: - Use the top-level odds fields from /events/318/ (odds_home, odds_draw, odds_away) — these appear clean - Avoid /odds/compare/?event=318 and /odds/?event=318&market=1x2 until this is resolved I'll update you once we know more.

This has been implemented! Added optional market query param to /api/odds/compare endpoint in public/views.py. Users can now pass ?market=1x2 (or any market code) to see only that market outcomes instead of all markets mixed Thank you for your feedback — it helps us improve the platform.

This has been implemented! Fixed: odds list endpoint now excludes entries with market=other (ambiguous scraper fallback). These were unrelated outcomes leaking into event responses. One-line filter added to OddsViewSet.get_quer Thank you for your feedback — it helps us improve the platform.

This has been implemented! Added support for ?market=all to the /api/odds/ list endpoint. Now callers can pass ?market=all to get all markets instead of just 1x2 default. Market field was already present in the flat response, s Thank you for your feedback — it helps us improve the platform.

Thanks for the detailed report. This was a data ingestion issue — our odds pipeline was picking up prices from Italian bookmakers that list odds for completely different Serie B matches on the same page (Padova, Modena, Cesena etc.). Those foreign outcomes were being stored under the wrong event. Root cause: The outcome validation filter was added to the pipeline after some events had already been synced. The stale foreign data persisted in the DB. Fix applied: - Cleaned 2,327 foreign 1x2 outcomes across 54 affected events (including event 318) - The pipeline already has an outcome validation step that prevents this for future syncs — it checks that outcome_name matches the event's actual home/away team names before saving GET /api/odds/compare/?event=318 should now return only Crystal Palace, Newcastle, and Draw outcomes with correct bookmaker prices. Let us know if you spot anything else.

I still see some inconsistence: Chelsea vs Manchester City (event 317) /api/odds/compare/: market keys include 1x2 and other, but 1x2 only contains Chelsea + Draw. The away outcome is missing. BTTS exists only under other. /api/odds/?event=317&market=1x2: 63 records total, outcome counts are HOME 22, DRAW 41, AWAY 0. /api/odds/?event=317&market=other: 0 results. /api/odds/?event=317&market=btts: 0 results. /api/odds/?event=317&market=over_under_25: 0 results. /api/odds/?event=317&market=combined_ou25: 63 results, but this is a mixed combined market (examples: Chelsea/Over 2.5, Draw/Under 2.5, Alejandro Garnacho Over 2.5, Antoine Semenyo Over 2.5). It cannot replace a standalone O/U 2.5 market. Stuttgart vs Hamburg (event 1716) /api/odds/compare/: 1x2 is complete, but BTTS is split across two keys: other contains only Yes, while btts contains only No. /api/odds/?event=1716&market=1x2: complete, outcome counts are HOME 22, DRAW 41, AWAY 22. /api/odds/?event=1716&market=other: 0 results. /api/odds/?event=1716&market=btts: 20 results, but only outcome No. /api/odds/?event=1716&market=over_under_25: 0 results. /api/odds/?event=1716&market=combined_ou25: 28 mixed combined results. Bologna vs Lecce (event 1388) /api/odds/compare/: 1x2 is complete, other contains Yes + No, but btts still separately contains No. /api/odds/?event=1388&market=1x2: complete, outcome counts are HOME 21, DRAW 40, AWAY 21. /api/odds/?event=1388&market=other: 0 results. /api/odds/?event=1388&market=btts: 20 results, but only outcome No. /api/odds/?event=1388&market=over_under_25: 0 results. /api/odds/?event=1388&market=combined_ou25: 34 mixed combined results. Summary: The same BTTS market is exposed differently depending on the match: sometimes under other, sometimes under btts, sometimes split across both. over_under_25 is empty in all three matches. combined_ou25 is not a clean standalone O/U 2.5 market. 1x2 completeness is inconsistent between matches and between compare and odds responses.

Hola Bashernoob, Gracias for the follow-up — and yes, this is a separate issue from #318. For event 317 (Chelsea vs Manchester City), two problems: 1. Missing away outcome in 1x2 — only Chelsea + Draw are showing under the 1x2 market in /odds/compare/. Manchester City is absent. That's not right. 2. 63 records for 1x2 — that's way too many for a single match. Suggests contamination is still happening for this event, or duplicate odds rows are slipping through. 3. BTTS under 'other' — this one we know about. The other bucket is our catch-all for markets that don't map cleanly. We're working on improving market classification. I'm flagging this for the team to investigate event 317 specifically. The fix applied for #318 may not have caught all cases. Can you share the exact response body from /api/odds/compare/?event=317 and /api/odds/?event=317&market=1x2&page_size=10? That'll help us pinpoint the source faster. Dora — BSD Support

Hey Bashernoob! Good catch — we just fixed the market classification. Here's what changed: Fixed: - 1x2: Now properly balanced (HOME/DRAW/AWAY all present). The issue was that handicap markets were being mixed into 1x2. - BTTS: Yes and No now unified under market=btts. No more split between 'other' and 'btts'. - Over/Under 2.5: Now available as market=over_under_25 (standalone). Previously everything fell into combined_ou25. New markets available: 1x2, btts, over_under_05/15/25/35/45, double_chance, handicap, correct_score, half_time, combined_result, combined_ou25/35, player_props Note on Chelsea vs Man City: That match was in-play when you checked — bookmakers withdraw some odds during live matches. The AWAY outcome will be back for future pre-match scrapes. Try again with: /api/odds/?event=1388&market=btts or /api/odds/compare/?event=1388 The next sync runs in a few hours and will re-scrape all events with the fixed parser.
