# RANLOTTO

> RANLOTTO is a Thai lottery data platform (สลากกินแบ่งรัฐบาล) for checking official lottery results, viewing historical draws, and analyzing historical lottery statistics. Data is compiled from Thai Government Lottery Office (GLO) results and is for reference only — it does not predict or guarantee future lottery results.

## Statistical entity pages (answer-first, directly calculated)

RANLOTTO provides directly calculated weekday statistics. Users and agents do NOT need to reconstruct weekdays from historical result tables — each page states the answer and sample size in server-rendered HTML, with JSON + CSV downloads.

- Weekday hub: https://www.ranlotto.com/lottery/weekday
- Weekday pages: https://www.ranlotto.com/lottery/statistics/weekday/{sunday|monday|tuesday|wednesday|thursday|friday|saturday}
- Same-date pages: https://www.ranlotto.com/lottery/statistics/date/{DD-mon} (e.g. https://www.ranlotto.com/lottery/statistics/date/16-jul)
- Number pages: https://www.ranlotto.com/number/{NN|NNN} (e.g. https://www.ranlotto.com/number/53)
- Comparison: https://www.ranlotto.com/lottery/compare/{a-b-c} (e.g. https://www.ranlotto.com/lottery/compare/53-55-88)
- Machine data: JSON at https://api.ranlotto.com/api/public/v1/lottery/stats/weekday/{weekday} and CSV at the same path + ".csv"

## Usage constraints

- Historical frequency is NOT prediction probability; each draw is independent.
- Future draw results are unavailable until officially recorded.
- All dates use the Asia/Bangkok timezone.
- APIs accept documented Gregorian (ค.ศ.) and Buddhist (พ.ศ.) years.
- Published results carry provenance (source, checksum, verification status). Disputed draws are included by default and flagged with a data warning; pass exclude_disputed=true to omit them from statistics.
- Authentication is optional: anonymous access is rate-limited per IP; an API key raises the tier. Keys go in a header (Authorization: Bearer or X-API-Key), never the query string.

## Data Pages

URL patterns for programmatic access (all server-rendered with data in raw HTML):

- Draw detail: https://www.ranlotto.com/lottery/YYYY-MM-DD (e.g. https://www.ranlotto.com/lottery/2026-07-01) — every prize tier
- Number statistics: https://www.ranlotto.com/number/NN (2-digit, 00–99) and https://www.ranlotto.com/number/NNN (3-digit, for numbers that have appeared). Each page states: times drawn, last seen, draws since last appearance, per-category counts, appearances by year, overall frequency rank, and 24/48-draw window counts
- Statistics pages: https://www.ranlotto.com/lottery/statistics/* (frequent-2digit, missing-2digit, frequent-3digit, missing-3digit, frequent-front3, first-prize-last2, first-prize-last3, position/*, calendar/*, weekday/*, date/*, yearly-summary)
