Installation

pip install novyx

Async Support (Optional)

pip install novyx[async]

CLI Installation (Optional)

pip install novyx[cli]

Quick Start (Sync)

from novyx import Novyx

nx = Novyx(api_key="nram_your_key_here")

# Store a memory
nx.remember("User prefers dark mode and async communication", tags=["preferences"])

# Search memories semantically

nx.rollback("2 hours ago")

Quick Start (Async)

from novyx import AsyncNovyx

async with AsyncNovyx(api_key="nram_your_key_here") as nx:
    await nx.remember("User prefers dark mode", tags=["preferences"])
    memories = await nx.recall("user preferences")
    health = await nx.eval_run()
    print(f"Health: {health['health_score']}/100")

Complete Lifecycle Example

from novyx import Novyx

nx = Novyx(api_key="nram_your_key_here")

# 1. Store memories
nx.remember("User mentioned budget is $50K for Q1", tags=["sales", "budget"], importance=8)
nx.remember("User prefers email over phone calls", tags=["preferences"], importance=7)
nx.remember("User is building a real estate AI assistant", tags=["project"])

# 2. Search with semantic recall
memories = nx.recall("what is the user's budget?", limit=3)
print(f"Found: {memories[0]['observation']}")

# 3. Check audit trail
audit = nx.audit(limit=5, operation="CREATE")
print(f"Created {len(audit)} memories")

# 4. Rollback if needed (Pro+ only)
# Preview what will change
preview = nx.rollback_preview("1 hour ago")
if preview["safe_rollback"]:
    result = nx.rollback("1 hour ago")
    print(f"Rolled back {result['operations_undone']} operations")

# 5. Trace agent actions (Pro+ only)
trace = nx.trace_create("sales-agent", session_id="session-123")
nx.trace_step(trace["trace_id"], "thought", "Analyzing budget — user has $50K")
nx.trace_step(trace["trace_id"], "action", "draft_proposal", metadata={"budget": 50000})
result = nx.trace_complete(trace["trace_id"])
print(f"Trace completed with signature: {result['signature'][:16]}...")

Features

🧠 Persistent Memory

Store observations about users, contexts, and decisions. Your AI remembers everything across sessions.

# Store with metadata
nx.remember(
    "Customer mentioned budget is $50K for Q1",
    tags=["sales", "budget"],
    importance=8,
    metadata={"customer_id": "12345", "quarter": "Q1"}
)

# List all memories
all_memories = nx.memories(limit=100, min_importance=7)
print(f"Found {len(all_memories)} high-importance memories")

# Get specific memory
memory = nx.memory("urn:uuid:abc123...")

# Delete memory
nx.forget("urn:uuid:abc123...")

🔍 Semantic Search

Find relevant memories using natural language queries. No exact keyword matching required. Send plain text — Novyx handles embedding generation server-side.

memories = nx.recall("what is the user working on?", limit=3)
# Returns: "User is building a real estate AI assistant"

# Filter by tags
memories = nx.recall("budget constraints", tags=["sales"], limit=5)

⏮️ Magic Rollback (Pro+)

Made a mistake? Roll back your AI's memory to any point in time.

# Preview rollback first
preview = nx.rollback_preview("2 hours ago")
print(f"Will restore {preview['artifacts_restored']} artifacts")
print(f"Warnings: {preview['warnings']}")

# Execute rollback
result = nx.rollback("2 hours ago")
print(f"Rolled back to {result['rolled_back_to']}")

# View rollback history
history = nx.rollback_history(limit=10)
for rb in history:
    print(f"Rollback to {rb['target_timestamp']}")

📜 Cryptographic Audit Trail

Every operation is logged with SHA-256 hashing for tamper-proof history.

# Get recent audit entries
audit = nx.audit(limit=50, operation="CREATE")

# Filter by time range
from datetime import datetime, timedelta
since = (datetime.now() - timedelta(days=7)).isoformat()
audit = nx.audit(since=since, operation="ROLLBACK")

# Export audit log (Pro+)
csv_data = nx.audit_export(format="csv")
with open("audit.csv", "wb") as f:
    f.write(csv_data)

# Verify integrity
verification = nx.audit_verify()
if verification["valid"]:
    print("✅ Audit trail integrity verified!")

🔐 Trace Audit (Pro+)

Track agent actions with RSA signatures and real-time policy enforcement.

# Create trace session
trace = nx.trace_create("my-agent", session_id="session-123")

# Add steps
nx.trace_step(trace["trace_id"], "thought", "Planning email")
nx.trace_step(trace["trace_id"], "action", "send_email", metadata={"to": "[e-mail]"})
nx.trace_step(trace["trace_id"], "observation", "Email sent successfully")

# Finalize with RSA signature
result = nx.trace_complete(trace["trace_id"])

# Verify integrity later
verification = nx.trace_verify(trace["trace_id"])
print(f"Verified {verification['steps_verified']} steps")

🌐 Context Spaces (Multi-Agent)

Create shared memory spaces for multi-agent collaboration with fine-grained permissions.

# Share a tag with another user
result = nx.share_context("project-notes", "[e-mail]", permission="write")

# List shared spaces
ctx = nx.shared_contexts()
for s in ctx["shared_by_me"]:
    print(f"Shared '{s['tag']}' with {s.get('shared_with_email')}")

# Store memory in a space
nx.remember("Shared insight", space_id="cs_abc123", tags=["shared"])

# Recall from a space
memories = nx.recall("insights", space_id="cs_abc123")

🔄 Replay — Time-Travel Debugging (Pro+)

Inspect how your agent's memory changed over time.

# Timeline of operations
timeline = nx.replay_timeline(since="2026-01-01T00:00:00Z", limit=50)
for event in timeline["entries"]:
    print(f"{event['timestamp']} - {event['operation']}")

# Point-in-time snapshot
snapshot = nx.replay_snapshot("2026-01-15T10:00:00Z")
print(f"{snapshot['total']} memories at that point")

# Full lifecycle of a memory
lifecycle = nx.replay_memory("urn:uuid:abc123...")

# Diff between two timestamps
diff = nx.replay_diff("2026-01-01T00:00:00Z", "2026-01-15T00:00:00Z")
print(f"Added: {diff['added']}, Removed: {diff['removed']}")

# Counterfactual recall (Enterprise)
result = nx.replay_recall("user preferences", at="2026-01-10T00:00:00Z")

🧬 Cortex — Autonomous Memory Intelligence (Pro+)

Your memory gets smarter on its own. Cortex consolidates near-duplicates, boosts frequently-recalled memories, decays forgotten ones, and generates insights.

# Check cortex status
status = nx.cortex_status()
print(f"Enabled: {status['enabled']}, Last run: {status['last_run_at']}")

# Configure cortex
nx.cortex_update_config(
    consolidation_enabled=True,
    consolidation_threshold=0.90,
    decay_age_days=30,
)

# Trigger a manual cycle
result = nx.cortex_run()
print(f"Consolidated: {result['consolidated']}, Boosted: {result['boosted']}, Decayed: {result['decayed']}")

# Get insights (Enterprise)
insights = nx.cortex_insights(limit=10)
for insight in insights["insights"]:
    print(f"Insight: {insight['observation']}")

📊 Eval — Memory Health Scoring

Score your agent's memory health, detect regressions, and gate CI/CD deployments.

# Run a health evaluation
result = nx.eval_run()
print(f"Health: {result['health_score']}/100")
print(f"Recall: {result['breakdown']['recall_consistency']}")
print(f"Drift: {result['breakdown']['drift_score']}")

# CI/CD gate — block deploys below threshold
gate = nx.eval_gate(min_score=80.0)
if not gate["passed"]:
    raise Exception(f"Memory health too low: {gate['health_score']}")

# Save baselines for regression testing
nx.eval_baseline_create("capital of France", "The capital of France is Paris")

# Check drift over time
drift = nx.eval_drift()
print(f"Memory count delta: {drift['memory_count_delta']}")

# View eval history
history = nx.eval_history(limit=10)
for entry in history["entries"]:
    print(f"{entry['created_at']}: {entry['health_score']}")

📊 Usage & Plans

Monitor your usage and explore pricing options.

# Check current usage
usage = nx.usage()
print(f"Tier: {usage['tier']}")
print(f"API calls: {usage['api_calls']['current']}/{usage['api_calls']['limit']}")
print(f"Memories: {usage['memories']['current']}")

# View available plans
plans = nx.plans()
for plan in plans:
    print(f"{plan['name']}: {plan['price_display']}")
    print(f"  Memories: {plan['memory_limit'] or 'Unlimited'}")
    print(f"  Features: {', '.join([k for k, v in plan['features'].items() if v])}")
