Overview

The Lamen Python SDK is a backend / machine-to-machine client for interacting with Lamen infrastructure services.

It provides API-key-authenticated access to:

• Messaging — send events, direct send, register device identities, register email identities, manage web tokens
• Storage — presigned upload, confirm upload, download URL, list objects, folders, privacy, delete
• Streaming / CDN — signed streaming and playback URLs
• Athena — ingest logic and analytics events
• Geocoding — structured location search

---

Authentication

All operations require a valid Lamen API key.

Authentication is handled automatically using the x-api-key header.

Example:

from lamen import Lamen

lamen = Lamen(api_key="lam_sk_live_...")

---

Quick Start (Sync)

from lamen import Lamen

lamen = Lamen(api_key="lam_sk_live_...")

response = lamen.messaging.post_event( event="user_signed_up", external_user_id="user_123", )

print(response)

---

Quick Start (Async)

import asyncio from datetime import datetime, timezone from lamen import AsyncLamen

async def main(): async with AsyncLamen(api_key="lam_sk_live_...") as lamen: await lamen.athena.ingest_event( external_user_id="user_123", event_name="signed_up", occurred_at=datetime.now(timezone.utc), properties={"plan": "free"}, idempotency_key="athena:signed_up:user_123:2026-02-01", )

asyncio.run(main())

---

Example: Storage Upload Flow

from lamen import Lamen

lamen = Lamen(api_key="lam_sk_live_...")

upload = lamen.storage.create_upload_url( filename="image.jpg", content_type="image/jpeg", size_bytes=1024, )

print(upload.uploadUrl)

Upload the file to upload.uploadUrl using your HTTP client

confirmed = lamen.storage.confirm_upload(object_id=upload.object_id)

print(confirmed)

---

Example: Streaming URL

stream = lamen.stream.get_stream_url( object_id="your-object-uuid", expiry_in_seconds=3600, )

print(stream.url)

---

Error Handling

The SDK raises typed exceptions:

AuthenticationError
BillingError
ValidationError
RateLimitError
TimeoutError
NetworkError
ApiError

Example:

from lamen import ValidationError

try: lamen.messaging.post_event(event="") except ValidationError as e: print("Invalid request:", e)

---

Retries & Idempotency

Retries are automatically enabled for transient failures:

408, 409, 425, 429, and 5xx responses.

For POST, PATCH, and PUT requests, retries are only enabled if an idempotency_key is provided.

Example:

from datetime import datetime, timezone

lamen.athena.ingest_event( external_user_id="user_123", event_name="purchase", occurred_at=datetime.now(timezone.utc), idempotency_key="purchase:user_123:1234", )

---

Status

Current version: BETA Testing.

Breaking changes may occur before version 1.0.0.
