print(response.report_type.value, response.sign, response.period.value)
for section in response.sections:
    print(f"[{section.section.value}] {section.summary}")

        target_date=date(2026, 4, 3),
        birth=BirthData(
            date=date(1997, 8, 17),
            time="09:30",
            coordinates=Coordinates(latitude=4.0511, longitude=9.7679),
            timezone="Africa/Douala",
        ),
    )
)

print(response.sign)
print(response.data.snapshot.rising_sign)
print(response.data.snapshot.house_cusps)

3) Planet-Focused Report

from datetime import date

from horoscope_engine.config import ServiceConfig
from horoscope_engine.models import Period, PlanetHoroscopeRequest, PlanetName
from horoscope_engine.service import HoroscopeService

service = HoroscopeService(ServiceConfig())

response = service.generate_planet(
    PlanetHoroscopeRequest(
        period=Period.MONTHLY,
        planet=PlanetName.MERCURY,
        sign="TAURUS",
