Usage Examples

Detect Specific Entities

# Detect only emails and phone numbers
result = client.tokenize(
    "Contact: John Doe, john@example.com, +1-555-1234",
    entities=["email address", "phone number"]
)
# Output: "Contact: John Doe, <email_address_1>, <phone_number_1>"

Use Policies (Recommended)

Instead of listing entities, use pre-configured policies:

# GDPR compliance (detects 15+ entity types)
result = client.tokenize(
    "Contact: John Doe, john@example.com, +49 30 12345",
    policy="gdpr_eu"
)

# Healthcare compliance (detects 11+ entity types)
result = client.tokenize(
    "Patient: Jane Smith, SSN: 123-45-6789",
    policy="hipaa_us"
)

Available Policies:

basic - Names, emails, phones (3 types)
gdpr_eu - GDPR compliance (15+ types)
hipaa_us - Healthcare compliance (11+ types)
pci_dss - Payment cards (8+ types)
strict - All entity types (60+)

Custom Entities

Define your own entity types using natural language:

# E-commerce custom entities
result = client.tokenize(
    "Order #ORD-2024-XYZ, SKU: PROD-789-BLU",
    entities=["order number", "product sku"]
)

# Healthcare custom entities
result = client.tokenize(
    "Patient in Ward 5B, Procedure Code: PROC-456",
    entities=["ward number", "procedure code"]
)

# Mix standard and custom
result = client.tokenize(
    "Customer John Doe (ID: CUST-789) ordered SKU-456",
    entities=["person", "customer id", "product sku"]
)

Custom entities work with zero-shot learning - no training required. Just describe what you want to detect in plain English.

Multilingual Support

All entities work across 15+ languages automatically:

# Detects entities in multiple languages
result = client.tokenize(
    "Cliente: María García, Email: maria@ejemplo.es, Telefon: +49 30 12345"
)
# Detects Spanish and German entities automatically
