SDK Reference

The Membase Python API at a glance (unibase-membase-sdk). Import everything from the top-level package:

from unibase_membase import Membase, Wallet

Wallet

Call	Returns	Notes
Wallet.from_env()	Wallet	from MEMBASE_PRIVATE_KEY
Wallet.from_key("0x…")	Wallet	from a raw private key
Wallet.generate()	Wallet	fresh keypair
wallet.address	str	the agent’s identity (0x…)

Agent

agent = Membase(wallet, config=None, *, hub=None, server_url="")

• config — optional Config / dict (see below); defaults otherwise.
• hub — inject a custom storage backend; defaults to the official Hub.
• server_url — set to enable metering / settlement via a Membase Server.
• agent.address — the wallet address. agent.close() — flush & release.

Memory — key-value

agent.private()                       # → handle for this wallet's private domain
handle.set(key: str, value)           # value: JSON-serializable
handle.get(key: str, *, author=None)  # → value | None

key is a path-like string (e.g. "notes/today"). private() is a single-member domain — only this wallet can decrypt.

Memory — recall

agent.memory.ingest(turns=[{"role": "user", "content": "..."}],
                    session_id=None, session_date=None)   # distill turns (Recovery)
agent.memory.recall(query: str, query_date: str, k: int = 10)  # ranked candidates, no LLM
agent.memory.answer(query: str, query_date: str)               # NL answer + citations (one LLM call)

ingest / answer need the recovery,runtime extras + an LLM key. query_date (ISO YYYY-MM-DD) scopes results to facts valid on that date.

Domains (shared memory)

team = agent.create_domain(domain_id: str)   # mint a domain key
team.set(key, value); team.get(key, author=agent.address)

code, _ = agent.invite_to(team)              # ECIES-wrapped key
handle, _ = other_agent.accept_invite(code)  # join the domain

See Domains & Encryption.

Cooperation (multi-agent)

The agent-direct protocol (signed logs, sessions, games) lives under unibase_membase.core.protocol and unibase_membase.games (rps, vote, auction, compare). For a server-mediated coordination API use Cooperation / MembaseClient. See Cooperation Protocol and examples/04_protocol.py.

Settlement (server-mediated)

from unibase_membase.client import MembaseClient
client = MembaseClient(wallet=wallet, server_url="https://…")
await client.settle_metering()        # flush metered usage on-chain (ERC-8183)

See Settlement.

Configuration

Pass a dict or Config instead of env vars (secrets stay in env):

from unibase_membase.client import MembaseClient
client = MembaseClient(
    wallet=Wallet.from_key(os.environ["MY_AGENT_KEY"]),
    config={"server": {"hub_url": "https://hub.membase.unibase.com"},
            "runtime": {"reader_model": "gpt-4o"}},
)

Config.from_json("path.json") and Config.from_dict({...}) also work. Unknown keys raise (typos won’t pass silently).
