API Documentation

The latindictionary.io REST API lets you look up Latin words, translate between Latin and English, parse Latin text with AI, and generate inflection tables — all programmatically.

Base URL: https://api.latindictionary.io/api/v1Python Package →GitHub →

Python Client

The easiest way to use the API is with the official Python client:

pip install latindictionary-io

from latindictionary_io import Client

client = Client()

# Latin → English
result = client.latin_to_english("canis")
print(result)

# English → Latin
result = client.english_to_latin("love")
print(result)

# Auto-detect language
result = client.auto_detect("amor")
print(result)

# AI-powered Latin parsing
result = client.latin_parse("arma virumque cano")
print(result)

# Inflection tables
result = client.inflection_table("amo")
print(result)

The Python client also supports async usage via AsyncClient. See the README for full documentation.
