durbl-sdk 0.2.2

Official Python client for the Durbl memory engine

Durbl Python SDK

The official Python client for the Durbl memory engine — a single backend that gives AI agents persistent, queryable memory across runs, sessions, and users. One API for write, recall, state, context, lifecycle, and signals — replacing a stack of vector DB + cache + queue + state store + summarizer.

Install

pip install durbl-sdk

Quickstart

from durbl_sdk import Durbl

client = Durbl(api_key="drbl_...")  # or set DURBL_API_KEY

# Write a memory
client.memory.write(
    entity="user/ahmed",
    content="Prefers TypeScript over JavaScript",
    type="preference",
    importance=0.8,
)

# Update entity state
client.state.update("user/ahmed", {"plan": "pro", "seats": 5})

# Recall by semantic search
hits = client.memory.recall(entity="user/ahmed", query="language preference", limit=3)
for m in hits:
    print(m["content"])

# Build a context window for an LLM call
ctx = client.context.build(entity="user/ahmed", goal="suggest a stack", max_memories=10)
print(ctx.assembled_context)

Async usage

Every resource has an a* mirror that uses httpx.AsyncClient:

import asyncio
from durbl_sdk import Durbl

async def main():
    async with Durbl(api_key="drbl_...") as client:
        await client.memory.awrite(entity="user/me", content="Likes coffee", type="preference")
        state = await client.state.aget("user/me")

asyncio.run(main())

Resources

Resource	Operations
client.memory	write · get · update · delete · list · recall
client.state	get · update · history
client.context	build · recall
client.events	write · list
client.intelligence	(analytics endpoints)
client.lifecycle	(memory lifecycle)
client.policies	(per-project policies)

Entity IDs

Entity IDs are free-form strings and may contain / (user/ahmed, team/acme/billing). The SDK percent-encodes them automatically when they appear in URL paths.

Error handling

from durbl_sdk.exceptions import DurblAPIError

try:
    client.memory.write(entity="user/me", content="...")
except DurblAPIError as e:
    print(e.status_code, e.message)

Examples

The examples/ directory has runnable sample apps:

• personal_coach — habit/goal tracker with semantic + preference memory
• recipe_memory — diet/preference-aware meal suggestions
• support_agent — per-customer briefs that demonstrate isolation
