Python API
from seedfaker import SeedFaker
f = SeedFaker(seed="ci", locale="en")
# Single values
f.field("name")
f.field("phone", e164=True)
f.field("credit-card", space=True)
f.field("email", omit=30) # "" for 30% of calls
# Weighted locales: 70% English, 20% German, 10% French
mixed = SeedFaker(seed="ci", locale="en=7,de=2,fr=1")
# Single correlated record
f.record(["name", "email", "phone"], ctx="strict")
# → {"name": "Zoe Kumar", "email": "zoe.kumar@...", "phone": "+1..."}
# Batch
f.records(["name", "email", "phone"], n=5, ctx="strict")
# Validate without generating
f.validate(["name", "email:e164"]) # raises ValueError if invalid
# Corruption
f.records(["name", "email", "ssn"], n=100, corrupt="high")
# Determinism — same seed = same output
a = SeedFaker(seed="test")
b = SeedFaker(seed="test")
assert a.field("name") == b.field("name")
# Fingerprint — detect algorithm changes after upgrade
SeedFaker.fingerprint() # 'sf0-...'
# All field names
SeedFaker.fields()
