Project description

ai-memory — Python SDK

Typed Python client for the ai-memory HTTP API. Wraps the daemon's /api/v1/ surface with sync and async clients, Pydantic v2 models that mirror the Rust structs, and HMAC-SHA256 webhook verification.

Status: 0.6.0-alpha.0 — scaffolding, unpublished. API may change before GA.

Install

# Not yet published; install from a local checkout:
pip install -e ./sdk/python

Requires Python 3.10+.

Quickstart

from ai_memory import AiMemoryClient, Tier

with AiMemoryClient(base_url="http://localhost:9077") as client:
    created = client.store(
        title="BIND9 build notes",
        content="Use --with-openssl=/opt/openssl, disable DoH for the lab.",
        tier=Tier.LONG,
        tags=["dns", "bind9"],
    )
    print(created["id"])

    hits = client.recall(context="how do I build BIND9?")
    for memory in hits.memories:
        print(memory.title, memory.confidence)

Async

import asyncio
from ai_memory import AsyncAiMemoryClient

async def main() -> None:
    async with AsyncAiMemoryClient(base_url="http://localhost:9077") as client:
        resp = await client.recall(context="hello")
        for memory in resp.memories:
            print(memory.title)

asyncio.run(main())

Authentication

API key

AiMemoryClient(base_url="https://memory.example.com", api_key="sk-...")

The key is sent as the X-API-Key header on every request. The server exempts /api/v1/health from auth.

mTLS

AiMemoryClient(
    base_url="https://memory.example.com",
    verify="/etc/ssl/certs/server-ca.pem",
    cert=("/etc/ssl/client/client.pem", "/etc/ssl/client/client.key"),
)

Agent identity (NHI)

Set agent_id to stamp the X-Agent-Id header on every request. The server writes metadata.agent_id accordingly (see CLAUDE.md §Agent Identity).

AiMemoryClient(base_url="http://localhost:9077", agent_id="ai:claude-opus-4.7@host")

All methods

Method	Endpoint	Notes
`health()`	`GET /api/v1/health`	Exempt from auth.
`metrics()`	`GET /api/v1/metrics`	Prometheus text format.
`store(...)`	`POST /api/v1/memories`	Upsert on `(title, namespace)`.
`bulk_store([...])`	`POST /api/v1/memories/bulk`	Up to 1000 per call.
`get(id)`	`GET /api/v1/memories/{id}`	Returns `Memory`.
`update(id, UpdateMemory)`	`PUT /api/v1/memories/{id}`	Partial update.
`delete(id)`	`DELETE /api/v1/memories/{id}`
`promote(id)`	`POST /api/v1/memories/{id}/promote`	Tier -> `long`.
`list(...)`	`GET /api/v1/memories`	Filters: namespace, tier, tags, agent_id.
`search(q, ...)`	`GET /api/v1/search`	FTS AND search.
`recall(context, ...)`	`POST /api/v1/recall`	Hybrid semantic + FTS.
`forget(...)`	`POST /api/v1/forget`	Bulk delete by pattern.
`link(a, b, relation)`	`POST /api/v1/links`	`related_to`, `supersedes`, `contradicts`, `derived_from`.
`get_links(id)`	`GET /api/v1/links/{id}`
`stats()`	`GET /api/v1/stats`
`namespaces()`	`GET /api/v1/namespaces`
`gc()`	`POST /api/v1/gc`
`export()` / `import_()`	`GET` / `POST /api/v1/export	import`
`subscribe(req)` / `unsubscribe(id)` / `subscriptions()`	`/api/v1/subscriptions`	Webhook mgmt.
`notify(req)` / `inbox(...)`	`/api/v1/notify`, `/api/v1/inbox`	Agent-to-agent messaging.
`grant(id, agent)` / `revoke(id, agent)`	`/api/v1/memories/{id}/grant	revoke`
`cluster(req)`	`POST /api/v1/cluster`	Peer management.
`agents()` / `register_agent(...)`	`/api/v1/agents`	NHI registry.

Webhook verification

from ai_memory import verify_webhook_signature

def handle(request) -> None:
    sig = request.headers["X-AI-Memory-Signature"]
    if not verify_webhook_signature(request.body, sig, secret="..."):
        raise PermissionError("bad signature")
    ...

body must be the raw bytes as received — do not re-encode a parsed JSON payload; whitespace differences will break the HMAC.

Errors

All SDK errors derive from AiMemoryError:

Exception	HTTP
`ValidationError`	400
`AuthError`	401
`ForbiddenError`	403
`NotFoundError`	404
`ConflictError`	409
`RateLimitError`	429
`ServerError`	5xx
`TransportError`	network failure
