Gematria API
Gematria and isopsephy as an API, computed locally and deterministically — turning words into the numeric sums of their letters. The hebrew endpoint computes Hebrew gematria: the standard value (Mispar Hechrachi) that adds the base value of each letter (alef 1, bet 2 … tav 400), the gadol value that counts the five final letters as 500–900, and the reduced digital root; for example שלום (shalom) is 376. The greek endpoint computes Greek isopsephy with the Milesian numeral system (alpha 1 … omega 800, plus the archaic stigma 6, koppa 90 and sampi 900), case-insensitively; for example λογος (logos) is 373. The english endpoint computes English gematria three ways — the ordinal or simple value (a 1 … z 26), the Pythagorean value that reduces each letter to a single digit 1–9, and the Sumerian value (ordinal × 6) — with the digital root; for example HELLO is 52 ordinal. Non-letter characters are ignored and unrecognised letters are listed. Everything is computed locally and deterministically, so it is instant and private. Ideal for word-game, puzzle, esoteric, study and language app developers, name-numerology and text-analysis tools, and Bible and classics study. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is letter-value gematria; for Roman numerals use a Roman-numeral API and for general number bases a base-conversion API.
