Installation

pip install smritea-sdk

Requires Python 3.9+.

Get your API key

1. Sign up at smritea.ai — free account, no credit card required
2. Create an app in the dashboard and copy your API key (sk-...) and App ID (app_...)
3. Export them as environment variables:

export SMRITEA_API_KEY="sk-..."
export SMRITEA_APP_ID="app_..."

Quickstart

import os
from smritea import SmriteaClient

client = SmriteaClient(
    api_key=os.environ["SMRITEA_API_KEY"],
    app_id=os.environ["SMRITEA_APP_ID"],
)

# Store something about a user
client.add("Alice is a vegetarian and loves hiking", user_id="alice")

# Retrieve it later in a different session
results = client.search("What are Alice's food preferences?", user_id="alice")
for r in results:
    print(f"{r.score:.2f}  {r.content}")

---

Constructor

from smritea import SmriteaClient

client = SmriteaClient(
    api_key="sk-...",                    # required
    app_id="app_...",                    # required
    base_url="https://api.smritea.ai",  # optional, default shown
    max_retries=2,                       # optional, default 2; 0 disables retry
)

Methods

add — Store a memory

memory = client.add(
    "User prefers concise replies",
    user_id="alice",               # shorthand for actor_id + actor_type="user"
    metadata={"source": "chat"},   # optional
    conversation_id="conv_123",    # optional
)
print(memory.id)  # mem_...

user_id is a shorthand — sets actor_id and forces actor_type="user". For agent or system memories use actor_id + actor_type directly.

Parameter	Default	Description
content	required	Memory text
user_id	None	Shorthand: actor_id + actor_type="user"
actor_id	None	Explicit actor ID
actor_type	"user"	"user" | "agent" | "system"
actor_name	None	Display name
metadata	None	Arbitrary key-value dict
conversation_id	None	Conversation context

---

search — Semantic search

results = client.search(
    "dietary restrictions",
    user_id="alice",
    limit=5,
    method="deep_search",  # "quick_search" | "deep_search" | "context_aware_search"
    threshold=0.7,          # min relevance score 0.0–1.0
)
for r in results:
    print(r.score, r.content)

Results are ordered by relevance (descending). Each result exposes score (0.0–1.0) and all Memory fields directly.

Search method	When to use
quick_search	Low-latency, keyword + vector hybrid
deep_search	Higher recall, traverses the memory graph
context_aware_search	Reranks results using conversation context

Parameter	Default	Description
query	required	Search text
user_id	None	Filter to this user's memories
actor_id	None	Filter by actor ID
actor_type	None	Filter by actor type
limit	app default	Max results to return
method	app default	Search strategy
threshold	None	Min relevance score 0.0–1.0
graph_depth	None	Graph traversal depth override
conversation_id	None	Conversation context

---

get — Retrieve a memory by ID

memory = client.get("mem_abc123")
print(memory.content, memory.created_at)
# Raises SmriteaNotFoundError if the ID does not exist

---

delete — Delete a memory by ID

client.delete("mem_abc123")
# Raises SmriteaNotFoundError if the ID does not exist

---

get_all — List all memories

Not yet implemented. Raises NotImplementedError. Use search() with a broad query as a workaround:

results = client.search("", user_id="alice", limit=100)

---

Error handling

from smritea import (
    SmriteaClient,
    SmriteaAuthError,
    SmriteaNotFoundError,
    SmriteaRateLimitError,
    SmriteaQuotaError,
    SmriteaValidationError,
    SmriteaError,
)

try:
    results = client.search("preferences", user_id="alice")
except SmriteaAuthError:
    print("Check your API key")
except SmriteaRateLimitError as e:
    print(f"Rate limited — retry after {e.retry_after}s")
except SmriteaQuotaError:
    print("Plan quota exceeded")
except SmriteaError as e:
    print(f"Unexpected error: {e}")

Exception	HTTP	When
SmriteaAuthError	401	Invalid or missing API key
SmriteaValidationError	400	Invalid request parameters
SmriteaNotFoundError	404	Memory ID does not exist
SmriteaQuotaError	402	Organisation quota exceeded
SmriteaRateLimitError	429	Rate limit hit — check .retry_after
SmriteaError	other	Unexpected server error
