Anonymous scraping confirmed feasible for marathonbet.by — site is fully SSR (nginx), no Cloudflare or JS challenge. HttpClient + AngleSharp + Polly v8 is sufficient; Playwright not required (kept as a future-flag). Spike outputs: - spike/SCRAPE_FINDINGS.md — page rendering, URL templates, anti-bot, rate limits, recommended scraping strategy for Phase 3. - spike/SCHEMA_DRAFT.md — customer-spec field → DOM selector mapping for Match + Period-N scope across football/basketball/tennis (hockey TBD). Phase 1+ handoff captured in subplan + CLAUDE.md. Critical Phase 8 finding: no public results endpoint at /su/results — phase 8 must switch to polling event-detail until eventJsonInfo.matchIsComplete=true (deviation flagged). Reviewer notes addressed: - Period market outcome codes corrected to RN_H/RN_D/RN_A (not 1/draw/3) and market name vocabulary clarified per-sport in SCHEMA_DRAFT §3.1. - results-page.html capture added to file list with caveat about live-landing score-state and unsampled hockey selectors.
maraphon-app
Sports betting odds analyzer for marathonbet.by.
Scrapes pre-match (/su) and live (/su/live) sports events, tracks coefficient changes
over time, and detects anomalies — in particular the "odds-flip" pattern where the
bookmaker freezes betting and then inverts underdog/favorite odds.
Tech stack
- .NET 8 + C# 12

- ClosedXML for Excel export
- AngleSharp for HTML scraping (with Playwright fallback for JS-rendered pages)
- Polly v8 for retry / circuit breaker / rate limiting
- MudBlazor UI components, Plotly.Blazor for charts
- Serilog structured logging
- xUnit / FluentAssertions / NSubstitute for tests
