yod 0.1.3

Official Python SDK for the Yod personal memory assistant API

Yod Python SDK

Official Python client for the Yod personal memory assistant API.

Installation

pip install yod

Quick Start

from yod import YodClient

# Initialize with your API key (get one from the dashboard)
client = YodClient(api_key="sk-yod-...")

# Ingest information
client.ingest_chat("My favorite color is blue and I love hiking on weekends")

# Query your memories
response = client.chat("What are my hobbies?")
print(response.answer)
# Output: "You love hiking on weekends."

print(response.citations)
# Output: [Citation(source_id='...', quote='I love hiking on weekends')]

Authentication

The SDK supports multiple authentication methods:

API Key (Recommended)

client = YodClient(api_key="sk-yod-...")

JWT Bearer Token

client = YodClient(bearer_token="eyJ...")

Development Mode (X-User-Id header)

client = YodClient(
    base_url="http://localhost:8000",
    user_id="test-user-123"
)

API Reference

Client Initialization

from yod import YodClient, AsyncYodClient

# Sync client
client = YodClient(
    api_key="sk-yod-...",           # API key
    base_url="https://api.yod.agames.ai",  # API base URL (optional)
    timeout=30.0,                      # Request timeout in seconds
    max_retries=3,                     # Max retry attempts
)

# Async client
async_client = AsyncYodClient(api_key="sk-yod-...")

Ingest Text

Store text and extract memories:

response = client.ingest_chat(
    text="I started learning piano last month. My teacher is Sarah.",
    source_id="conversation-123",  # Optional: track the source
    timestamp="2024-01-15T10:30:00Z",  # Optional: set timestamp
)

print(response.source_id)  # Source identifier
print(response.chunks)     # Number of chunks processed
print(response.entities)   # Extracted entities (people, places, etc.)
print(response.memories)   # Extracted memories

Chat / Query

Query your memories with natural language:

response = client.chat(
    question="Who is my piano teacher?",
    language="en",  # Optional: response language
    as_of="2024-06-01T00:00:00Z",  # Optional: temporal query
)

print(response.answer)          # "Your piano teacher is Sarah."
print(response.citations)       # Source citations with quotes
print(response.used_memory_ids) # Memory IDs used to generate answer

List Memories

memories = client.list_memories(
    limit=50,              # Max memories to return
    kind="preference",     # Filter by type (preference, event, fact, etc.)
    search="piano",        # Search term
    include_inactive=False # Include superseded memories
)

for memory in memories.memories:
    print(f"[{memory.kind}] {memory.summary} (confidence: {memory.confidence})")

Get Single Memory

memory = client.get_memory("mem_abc123")
print(memory.summary)
print(memory.entity_ids)  # Related entities
print(memory.support)     # Supporting sources with quotes

Update Memory

client.update_memory(
    "mem_abc123",
    summary="Updated summary text",
    confidence=0.95,
    kind="fact"
)

Delete Memory

client.delete_memory("mem_abc123")

Memory History

Get temporal versions of a memory:

history = client.get_memory_history("mem_abc123")
for version in history.memories:
    print(f"{version.updated_at}: {version.summary}")

Health Checks

# Basic health check
health = client.health()
print(health.status)  # "ok"

# Detailed readiness check
ready = client.ready()
print(ready.status)      # "ok" or "degraded"
print(ready.neo4j.ok)    # Neo4j status
print(ready.qdrant.ok)   # Qdrant status

Async Usage

All methods are available as async:

from yod import AsyncYodClient

async def main():
    async with AsyncYodClient(api_key="sk-yod-...") as client:
        # Ingest
        await client.ingest_chat("I enjoy reading science fiction")

        # Query
        response = await client.chat("What kind of books do I like?")
        print(response.answer)

        # List memories
        memories = await client.list_memories()
        for m in memories.memories:
            print(m.summary)

import asyncio
asyncio.run(main())

Error Handling

The SDK provides specific exception types:

from yod import (
    YodError,           # Base exception
    YodAPIError,        # API returned an error
    AuthenticationError,  # 401 - Invalid credentials
    AuthorizationError,   # 403 - Insufficient permissions
    NotFoundError,        # 404 - Resource not found
    ValidationError,      # 422 - Invalid request
    RateLimitError,       # 429 - Rate limit exceeded
    ServerError,          # 5xx - Server error
    YodConnectionError, # Network error
    YodTimeoutError,    # Request timeout
)

try:
    response = client.chat("What's my name?")
except AuthenticationError:
    print("Invalid API key")
except RateLimitError as e:
    print(f"Rate limited. Retry after {e.retry_after} seconds")
except YodAPIError as e:
    print(f"API error {e.status_code}: {e}")
except YodError as e:
    print(f"SDK error: {e}")

Models

Response Models

from yod import (
    ChatResponse,
    Citation,
    IngestResponse,
    MemoryItem,
    MemoryListResponse,
    MemorySupport,
    HealthResponse,
    ReadyResponse,
)

Enums

from yod import MemoryKind, MemoryStatus, EntityType

# Memory kinds
MemoryKind.PREFERENCE   # User preferences
MemoryKind.FACT         # General facts
MemoryKind.EVENT        # Events and activities
MemoryKind.RELATIONSHIP # Relationships between entities
MemoryKind.GOAL         # Goals and aspirations
MemoryKind.OPINION      # Opinions and beliefs

Configuration

Custom Base URL

# Self-hosted instance
client = YodClient(
    api_key="sk-yod-...",
    base_url="https://yod.yourcompany.com"
)

# Local development
client = YodClient(
    base_url="http://localhost:8000",
    user_id="dev-user"
)

Timeouts

client = YodClient(
    api_key="sk-yod-...",
    timeout=60.0,        # Request timeout
    connect_timeout=10.0 # Connection timeout
)

Retry Configuration

The SDK automatically retries failed requests with exponential backoff:

client = YodClient(
    api_key="sk-yod-...",
    max_retries=5  # Default: 3
)

Retries are performed for:

• 429 Too Many Requests (respects Retry-After header)
• 500, 502, 503, 504 Server Errors
• Connection errors
