Sovant Memory-as-a-Service Python SDK

Sovant Python SDK

Sovant is Memory-as-a-Service: a durable, queryable memory layer for AI apps with cross-model recall, hybrid (semantic + deterministic) retrieval, and simple SDKs.

Installation

pip install sovant

Quick Start

from sovant import Sovant

# Initialize the client
client = Sovant(api_key="sk_live_your_api_key_here", base_url="https://sovant.ai")

# Create a memory
mem = client.memory.create({
    "content": "User prefers dark mode",
    "type": "preference",
    "tags": ["ui", "settings"]
})

# Search memories
results = client.memory.search({
    "query": "user preferences",
    "limit": 10
})

# Update a memory
updated = client.memory.update(mem["id"], {
    "tags": ["ui", "settings", "theme"]
})

# Delete a memory
client.memory.delete(mem["id"])

Chat in 60 Seconds

Stream real-time chat responses with memory context:

from sovant import Sovant
import sys

client = Sovant(api_key="sk_live_your_api_key_here", base_url="https://sovant.ai")

# Create a chat session
session = client.chat.create_session({"title": "Demo"})

# Stream a response
stream = client.chat.send_message(
    session["id"],
    "hello",
    {
        "provider": "openai",
        "model": "gpt-4o-mini",
        "use_memory": True
    },
    stream=True
)

for ev in stream:
    if ev["type"] == "delta":
        sys.stdout.write(ev.get("data", ""))
    elif ev["type"] == "done":
        print("\n[done]")

# Get chat history
messages = client.chat.get_messages(session["id"])

Profile Recall Helpers

Save and recall user profile facts with canonical patterns:

# Extract profile entity from text
fact = client.recall.extract_profile("i'm from kuching")
# -> {"entity": "location", "value": "kuching"} | None

if fact:
    client.recall.save_profile_fact(fact)  # canonicalizes and persists

# Get all profile facts
profile = client.recall.get_profile_facts()
# -> {"name": "...", "age": "...", "location": "...", "preferences": [...]}

Configuration

from sovant import Sovant

client = Sovant(
    api_key="sk_live_your_api_key_here",  # Required
    base_url="https://sovant.ai",         # Optional, API endpoint
    timeout=30.0,                          # Optional, request timeout in seconds (default: 30.0)
    max_retries=3,                         # Optional, max retry attempts (default: 3)
    debug=False,                           # Optional, enable debug logging (default: False)
)

The SDK handles dual authentication automatically, preferring the x-sovant-api-key header over Authorization: Bearer.

API Reference

Memory Operations

Create Memory

memory = client.memory.create({
    "content": "Customer contacted support about billing",
    "type": "observation",          # 'journal' | 'insight' | 'observation' | 'task' | 'preference'
    "tags": ["support", "billing"],
    "metadata": {"ticket_id": "12345"},
    "thread_id": "thread_abc123",   # Optional thread association
})

List Memories

memories = client.memory.list({
    "limit": 20,                    # Max items per page (default: 20)
    "offset": 0,                    # Pagination offset
    "tags": ["billing"],            # Filter by tags
    "type": "observation",          # Filter by type
    "is_archived": False,           # Filter archived status
})

print(memories["memories"])         # Array of memories
print(memories["total"])            # Total count
print(memories["has_more"])         # More pages available

Get Memory by ID

memory = client.memory.get("mem_123abc")

Update Memory (Partial)

updated = client.memory.update("mem_123abc", {
    "tags": ["support", "billing", "resolved"],
    "metadata": {
        **memory.get("metadata", {}),
        "resolved": True,
    },
    "is_archived": True,
})

Replace Memory (Full)

replaced = client.memory.put("mem_123abc", {
    "content": "Updated content here",  # Required for PUT
    "type": "observation",
    "tags": ["updated"],
})

Delete Memory

client.memory.delete("mem_123abc")

Search Memories

# Semantic search
semantic_results = client.memory.search({
    "query": "customer preferences about notifications",
    "limit": 10,
    "type": "preference",
})

# Filter-based search
filter_results = client.memory.search({
    "tags": ["settings", "notifications"],
    "from_date": "2024-01-01",
    "to_date": "2024-12-31",
    "limit": 20,
})

Batch Operations

batch = client.memory.batch({
    "operations": [
        {
            "op": "create",
            "data": {
                "content": "First memory",
                "type": "journal",
            },
        },
        {
            "op": "update",
            "id": "mem_123abc",
            "data": {
                "tags": ["updated"],
            },
        },
        {
            "op": "delete",
            "id": "mem_456def",
        },
    ],
})

print(batch["results"])         # Individual operation results
print(batch["summary"])         # Summary statistics

Thread Management

Associate memories with conversation threads:

# Create a thread
thread = client.threads.create({
    "title": "Customer Support Session",
    "metadata": {"user_id": "user_123"}
})

# List threads
threads = client.threads.list({
    "limit": 10,
    "offset": 0
})

# Get thread by ID
thread = client.threads.get("thread_abc123")

# Update thread
updated_thread = client.threads.update("thread_abc123", {
    "title": "Resolved: Billing Issue",
    "metadata": {"status": "resolved"}
})

# Delete thread
client.threads.delete("thread_abc123")

# Link memory to thread
client.threads.link_memory("thread_abc123", "mem_123abc")

# Create memories within a thread
memory1 = client.memory.create({
    "content": "User asked about pricing",
    "type": "observation",
    "thread_id": "thread_abc123",
})

memory2 = client.memory.create({
    "content": "User selected enterprise plan",
    "type": "observation",
    "thread_id": "thread_abc123",
})

# List memories in a thread
thread_memories = client.memory.list({
    "thread_id": "thread_abc123",
})

API Key Management

Manage API keys programmatically:

# List all API keys
keys = client.keys.list()
print(keys)  # Array of key objects

# Create a new API key
new_key = client.keys.create({"name": "CI key"})
print(new_key["key"])  # The actual secret key (only shown once!)

# Update key metadata
client.keys.update(new_key["id"], {"name": "Production key"})

# Revoke a key
client.keys.revoke(new_key["id"])

Memory Types

• journal - Chronological entries and logs
• insight - Derived patterns and conclusions
• observation - Factual, observed information
• task - Action items and todos
• preference - User preferences and settings

Error Handling

The SDK provides typed errors for better error handling:

from sovant import Sovant, SovantError, AuthError, RateLimitError, NetworkError, TimeoutError

try:
    memory = client.memory.get("invalid_id")
except AuthError as e:
    print(f"Authentication failed: {e}")
    # Handle authentication error
except RateLimitError as e:
    print(f"Rate limit exceeded: {e}")
    print(f"Retry after: {e.retry_after}")
    # Handle rate limiting
except NetworkError as e:
    print(f"Network error: {e}")
    # Handle network issues
except TimeoutError as e:
    print(f"Request timed out: {e}")
    # Handle timeout
except SovantError as e:
    print(f"API Error: {e}")
    print(f"Status: {e.status}")
    print(f"Request ID: {e.request_id}")

    if e.status == 404:
        # Handle not found
        pass
    elif e.status == 400:
        # Handle bad request
        pass

Advanced Features

Retry Configuration

The SDK automatically retries failed requests with exponential backoff:

client = Sovant(
    api_key="sk_live_...",
    max_retries=5,           # Increase retry attempts
    timeout=60.0,            # Increase timeout for slow connections
)

Debug Mode

Enable debug logging to see detailed request/response information:

client = Sovant(
    api_key="sk_live_...",
    debug=True,              # Enable debug output
)

Custom Base URL

Connect to different environments:

client = Sovant(
    api_key="sk_live_...",
    base_url="https://staging.sovant.ai",
)

Best Practices

1. Use appropriate memory types - Choose the correct type for your use case
2. Add meaningful tags - Tags improve searchability and organization
3. Use threads - Group related memories together
4. Handle errors gracefully - Implement proper error handling
5. Batch operations - Use batch API for multiple operations
6. Archive don't delete - Consider archiving instead of deleting

Examples

Customer Support Integration

# Track customer interaction
interaction = client.memory.create({
    "content": "Customer reported slow dashboard loading",
    "type": "observation",
    "thread_id": f"ticket_{ticket_id}",
    "tags": ["support", "performance", "dashboard"],
    "metadata": {
        "ticket_id": ticket_id,
        "customer_id": customer_id,
        "priority": "high",
    },
})

# Record resolution
resolution = client.memory.create({
    "content": "Resolved by clearing cache and upgrading plan",
    "type": "insight",
    "thread_id": f"ticket_{ticket_id}",
    "tags": ["support", "resolved"],
    "metadata": {
        "ticket_id": ticket_id,
        "resolution_time": "2h",
    },
})

User Preference Tracking

# Store preference
preference = client.memory.create({
    "content": "User prefers email notifications over SMS",
    "type": "preference",
    "tags": ["notifications", "email", "settings"],
    "metadata": {
        "user_id": user_id,
        "setting": "notification_channel",
        "value": "email",
    },
})

# Query preferences
preferences = client.memory.search({
    "query": "notification preferences",
    "type": "preference",
    "tags": ["notifications"],
})

Rate Limiting

The API implements rate limiting. The SDK automatically handles rate limit responses with retries. Rate limit headers are included in responses:

• X-RateLimit-Limit - Request limit per window
• X-RateLimit-Remaining - Remaining requests
• X-RateLimit-Reset - Reset timestamp
