pip install lara-sdk

Basic Usage

import os
from lara_sdk import Credentials, Translator

# Set your credentials using environment variables (recommended)
credentials = Credentials(
  os.environ.get('LARA_ACCESS_KEY_ID'),
  os.environ.get('LARA_ACCESS_KEY_SECRET')
)

# Create translator instance
lara = Translator(credentials)

# Simple text translation
try:
  result = lara.translate("Hello, world!", target="fr-FR", source="en-US")
  print(f"Translation: {result.translation}")
  # Output: Translation: Bonjour, le monde !
except Exception as error:
  print(f"Translation error: {error}")

🔧 API Reference

Core Components

🔐 Authentication

The SDK supports authentication via access key and secret:

from lara_sdk import Credentials, Translator

credentials = Credentials("your-access-key-id", "your-access-key-secret")
lara = Translator(credentials)

Environment Variables (Recommended):

export LARA_ACCESS_KEY_ID="your-access-key-id"
export LARA_ACCESS_KEY_SECRET="your-access-key-secret"

import os
from lara_sdk import Credentials

credentials = Credentials(
    os.environ['LARA_ACCESS_KEY_ID'],
    os.environ['LARA_ACCESS_KEY_SECRET']
)

Alternative Constructor:

# You can also pass credentials directly to Translator
lara = Translator(
    access_key_id="your-access-key-id",
    access_key_secret="your-access-key-secret"
)

🌍 Translator

# Create translator with credentials
lara = Translator(credentials)

Text Translation

# Basic translation
result = lara.translate("Hello", target="fr-FR", source="en-US")

# Multiple strings
result = lara.translate(["Hello", "World"], target="fr-FR", source="en-US")

# TextBlocks (mixed translatable/non-translatable content)
from lara_sdk import TextBlock

text_blocks = [
    TextBlock(text="Translatable text", translatable=True),
    TextBlock(text="<br>", translatable=False),  # Non-translatable HTML
    TextBlock(text="More translatable text", translatable=True)
]
result = lara.translate(text_blocks, target="fr-FR", source="en-US")

# With advanced options

result = lara.translate(
    "Hello",
    target="fr-FR",
    source="en-US",
    instructions=["Formal tone"],
    adapt_to=["memory-id"],  # Replace with actual memory IDs
    glossaries=["glossary-id"],  # Replace with actual glossary IDs
    style="fluid",
    timeout_ms=10000
)

📖 Document Translation

Simple document translation

translated_content = lara.documents.translate(
    file_path="/path/to/your/document.txt",  # Replace with actual file path
    filename="document.txt",
    source="en-US",
    target="fr-FR"
)

# With options
translated_content = lara.documents.translate(
    file_path="/path/to/your/document.txt",  # Replace with actual file path
    filename="document.txt",
    source="en-US",
    target="fr-FR",
    adapt_to=["mem_1A2b3C4d5E6f7G8h9I0jKl"],  # Replace with actual memory IDs
    glossaries=["gls_1A2b3C4d5E6f7G8h9I0jKl"],  # Replace with actual glossary IDs
    style="fluid"
)

Document translation with status monitoring

Document upload

#Optional: upload options
document = lara.documents.upload(
    file_path="/path/to/your/document.txt",  # Replace with actual file path
    filename="document.txt",
    source="en-US",
    target="fr-FR",
    adapt_to=["mem_1A2b3C4d5E6f7G8h9I0jKl"],  # Replace with actual memory IDs
    glossaries=["gls_1A2b3C4d5E6f7G8h9I0jKl"]  # Replace with actual glossary IDs
)

Document translation status monitoring

status = lara.documents.status(document.id)

Download translated document

translated_content = lara.documents.download(document.id)

🖼️ Image Translation

Simple image translation

translated_image = lara.images.translate(
  source="en-US",
  target="fr-FR",
  image_path="/path/to/your/image.png",  # Replace with actual file path
  model="overlay"
)

Text-only image translation

text_results = lara.images.translate_text(
  source="en-US",
  target="it-IT",
  image_path="/path/to/your/image.png",  # Replace with actual file path
  include_layout=True
)

When include_layout=True, the result is typed as ImageTextResult[ImageLayoutParagraph], and every paragraph includes the layout required by classic rendering models. Pass the paragraphs directly to the renderer:

from lara_sdk import ImageParagraph

# Edit the translation while retaining the layout returned by translate_text.
text_results.paragraphs[0].translation = "Ciao mondo!"

rendered_image = lara.images.render_translated(
    image_path="/path/to/your/image.png",
    source=text_results.source_language,
    target="it-IT",
    paragraphs=text_results.paragraphs,
    model="overlay",
)

# Generative models accept text-only paragraphs. When model is omitted, the
# API uses generative_fast.
text_only_paragraphs = [
    ImageParagraph(text=p.text, translation=p.translation)
    for p in text_results.paragraphs
]
rendered_image = lara.images.render_translated(
    image_path="/path/to/your/image.png",
    source=None,
    target="it-IT",
    paragraphs=text_only_paragraphs,
)

render_translated renders supplied translations without translating them again. overlay and inpainting require every paragraph to be an ImageLayoutParagraph, containing bbox, lines_bboxes, text_info, and alignment. generative, generative_fast, and the omitted-model default accept either ImageParagraph or ImageLayoutParagraph. The overloads express these model-dependent requirements to Python type checkers. Set no_trace=True to disable request tracing.

🎵 Audio Translation

Simple audio translation

audio_content = lara.audio.translate(
    file_path="/path/to/your/audio.mp3",  # Replace with actual file path
    filename="audio.mp3",
    source="en-US",
    target="fr-FR"
)

# With options
audio_content = lara.audio.translate(
    file_path="/path/to/your/audio.mp3",  # Replace with actual file path
    filename="audio.mp3",
    source="en-US",
    target="fr-FR",
    adapt_to=["mem_1A2b3C4d5E6f7G8h9I0jKl"],  # Replace with actual memory IDs
    glossaries=["gls_1A2b3C4d5E6f7G8h9I0jKl"]  # Replace with actual glossary IDs
)

    target="fr-FR",
    adapt_to=["mem_1A2b3C4d5E6f7G8h9I0jKl"],  # Replace with actual memory IDs
    glossaries=["gls_1A2b3C4d5E6f7G8h9I0jKl"]  # Replace with actual glossary IDs
)

audio_content = lara.audio.download(audio.id)

🎙️ Audio Transcript Translation

Simple transcript translation

result = lara.audio.translate_transcript(
    file_path="/path/to/your/audio.mp3",  # Replace with actual file path
    filename="audio.mp3",
    source="en-US",
    target="fr-FR"
)

# With options
result = lara.audio.translate_transcript(
    file_path="/path/to/your/audio.mp3",  # Replace with actual file path
    filename="audio.mp3",
    source="en-US",
    target="fr-FR",
    adapt_to=["mem_1A2b3C4d5E6f7G8h9I0jKl"],  # Replace with actual memory IDs
    glossaries=["gls_1A2b3C4d5E6f7G8h9I0jKl"]  # Replace with actual glossary IDs
)

result = lara.audio.get_translated_transcript(audio.id)

🧠 Memory Management

# Create memory
memory = lara.memories.create("MyMemory")

# Create memory with external ID (MyMemory integration)
memory = lara.memories.create("Memory from MyMemory", external_id="aabb1122")  # Replace with actual external ID

# Important: To update/overwrite a translation unit you must provide a tuid. Calls without a tuid always create a new unit and will not update existing entries.
# Add translation to single memory
memory_import = lara.memories.add_translation("mem_1A2b3C4d5E6f7G8h9I0jKl", "en-US", "fr-FR", "Hello", "Bonjour", tuid="greeting_001")

# Add translation to multiple memories

# TMX import with a callback URL (notified when the import completes)
memory_import = lara.memories.import_tmx(
    "mem_1A2b3C4d5E6f7G8h9I0jKl",
    "/path/to/your/memory.tmx",
    callback_url="https://your-server.example.com/lara/import-callback"

lara.memories.revoke_group_share(team_memory.id, "grp_1A2b3C4d5E6f7G8h9I0jKl")
lara.memories.revoke_account_share(team_memory.id)

📚 Glossary Management

# Create glossary
glossary = lara.glossaries.create("MyGlossary")

# Import a glossary file (use content_type="tbx" for TBX files)
glossary_import = lara.glossaries.import_file("gls_1A2b3C4d5E6f7G8h9I0jKl", "/path/to/your/glossary.csv")

# All options are keyword-only. The default content_type is "csv/table-uni".
# lara.glossaries.import_file(glossary.id, "/path/to/glossary.tbx", content_type="tbx")

# Import CSV with a callback URL (async notification when the import completes)
glossary_import = lara.glossaries.import_file(
    "gls_1A2b3C4d5E6f7G8h9I0jKl",
    "/path/to/your/glossary.csv",
    callback_url="https://your-server.example.com/lara/import-callback"
)

# Check import status
import_status = lara.glossaries.get_import_status(import_id)

# Wait for import completion
completed_import = lara.glossaries.wait_for_import(glossary_import, max_wait_time=300)  # 5 minutes

# Export glossary
csv_data = lara.glossaries.export("gls_1A2b3C4d5E6f7G8h9I0jKl", "csv/table-uni", "en-US")

# Async glossary export - returns a job_id; the result is delivered to your callback URL when ready
glossary_export = lara.glossaries.export_async(
    "gls_1A2b3C4d5E6f7G8h9I0jKl",
    callback_url="https://your-server.example.com/lara/export-callback",
    content_type="csv/table-uni",
    source="en-US"
)
job_id = glossary_export.job_id

# Get glossary terms count
counts = lara.glossaries.counts("gls_1A2b3C4d5E6f7G8h9I0jKl")

# Account and group sharing use the same add, rename, list, and revoke workflow
lara.glossaries.add_account_share(glossary.id, "Team glossary")
glossary_shares = lara.glossaries.get_shares(glossary.id)
lara.glossaries.revoke_account_share(glossary.id)

📋 Styleguide Management

# Create styleguide
styleguide = lara.styleguides.create("MyStyleguide", "Always use formal language.")

# List all styleguides
styleguides = lara.styleguides.list()

# Get a specific styleguide
styleguide = lara.styleguides.get("stg_1A2b3C4d5E6f7G8h9I0jKl")

# Update styleguide — pass None for fields you don't want to change
# Update only the name
styleguide = lara.styleguides.update("stg_1A2b3C4d5E6f7G8h9I0jKl", "UpdatedStyleguide")

# Update only the content
styleguide = lara.styleguides.update("stg_1A2b3C4d5E6f7G8h9I0jKl", content="Always use informal language.")

# Update both
styleguide = lara.styleguides.update("stg_1A2b3C4d5E6f7G8h9I0jKl", "UpdatedStyleguide", "Always use informal language.")

# Share a styleguide and inspect all visible account, group, and user shares
lara.styleguides.add_group_share(styleguide.id, "grp_1A2b3C4d5E6f7G8h9I0jKl", "Marketing styleguide")
styleguide_shares = lara.styleguides.get_shares(styleguide.id)

# Delete styleguide
styleguide = lara.styleguides.delete("stg_1A2b3C4d5E6f7G8h9I0jKl")

🌐 Language Detection

# Basic language detection
result = lara.detect("Hello, world!")
print(f"Detected language: {result.language}")
print(f"Content type: {result.content_type}")

# Detect multiple strings
result = lara.detect(["Hello", "Bonjour", "Hola"])

# Detection with hint
result = lara.detect("Hello", hint="en")

# Detection with passlist (restrict to specific languages)
result = lara.detect(
    "Guten Tag",
    passlist=["de-DE", "en-US", "fr-FR"]
)

# Combined hint and passlist
result = lara.detect(
    "Buongiorno",
    hint="it",
    passlist=["it-IT", "es-ES", "pt-PT"]
)

🎯 Quality Estimation

Use quality_estimation() to score how well a translation matches its source. Pass a single sentence/translation pair to get a single result, or two parallel lists to get one result per pair.

# Single pair
single = lara.quality_estimation(
    source="en-US",
    target="it-IT",
    sentence="Hello, how are you today?",
    translation="Ciao, come stai oggi?",
)
print(single.score)  # e.g. 0.768

# Batch
batch = lara.quality_estimation(
    source="en-US",
    target="it-IT",
    sentence=["Good morning.", "The weather is nice."],
    translation=["Buongiorno.", "Il tempo è bello."],
)
print([r.score for r in batch])  # e.g. [0.751, 0.713]

Translation Options

result = lara.translate(
    text,
    target="fr-FR",                          # Target language (required)
    source="en-US",                          # Source language (optional, auto-detect if None)
    source_hint="en",                        # Hint for source language detection
    adapt_to=["memory-id"],                  # Memory IDs to adapt to
    glossaries=["glossary-id"],              # Glossary IDs to use
    instructions=["instruction"],            # Translation instructions
    style="fluid",                           # Translation style (fluid, faithful, creative)
    content_type="text/plain",               # Content type (text/plain, text/html, etc.)
    multiline=True,                          # Enable multiline translation
    timeout_ms=10000,                        # Request timeout in milliseconds
    no_trace=False,                          # Disable request tracing
    verbose=False,                           # Enable verbose response
)

Language Codes

The SDK supports full language codes (e.g., en-US, fr-FR, es-ES) as well as simple codes (e.g., en, fr, es):

# Full language codes (recommended)
result = lara.translate("Hello", target="fr-FR", source="en-US")

# Simple language codes
result = lara.translate("Hello", target="fr", source="en")

🌐 Supported Languages

The SDK supports all languages available in the Lara API. Use the languages() method to get the current list:

languages = lara.languages()
print(f"Supported languages: {', '.join(languages)}")

Asset permissions

Memory, Glossary, and Styleguide expose permission_mask: Optional[PermissionMask]. All existing resource classes and method return types are unchanged. The value is None when the API omits the field, including POST, PUT, and DELETE resource responses.

GET list and detail responses contain the combined effective mask from the caller's applicable shares. Resources embedded in GET /shares responses contain the selected share's stored mask; individual share entries contain their own stored masks. Masks use read (r), write (w), export (e), and share (s) positions, with - for absent permissions. Supported values are r---, rw--, r-e-, r--s, rwe-, rw-s, r-es, and rwes.

Share entries expose a required permission_mask, matching the service contract. Resource masks remain optional. The legacy permissions field and the MemorySharePermission, GlossarySharePermission, and StyleguideSharePermission aliases have been removed. Use permission_mask to inspect the read, write, export, and share bits.

⚙️ Configuration

Error Handling

The SDK provides detailed error information:

from lara_sdk import LaraApiError, LaraError

try:
    result = lara.translate("Hello", target="fr-FR", source="en-US")
    print(f"Translation: {result.translation}")
except LaraApiError as error:
    print(f"API Error [{error.status_code}]: {error.message}")
    print(f"Error type: {error.type}")
except LaraError as error:
    print(f"SDK Error: {error}")
except Exception as error:
    print(f"Unexpected error: {error}")
