Best Practices for Danish Parliament API

Optimal Query Patterns:

# Efficient pagination
def get_all_data(entity, batch_size=1000):
    skip = 0
    all_data = []

    while True:
        url = f"https://oda.ft.dk/api/{entity}?$top={batch_size}&$skip={skip}"
        response = requests.get(url)
        data = response.json()

        if not data['value']:
            break

        all_data.extend(data['value'])
        skip += batch_size

    return all_data

Performance Optimization: - Use $select to limit field returns - Batch related queries with $expand - Implement client-side caching for static data - Monitor response times and adjust query complexity

Multi-API Integration Architecture

Recommended Stack:

# API abstraction layer
class ParliamentAPI:
    def __init__(self, country):
        self.config = self.get_config(country)
        self.session = requests.Session()
        if self.config.get('auth'):
            self.session.headers.update({
                'Authorization': self.config['auth']
            })

    def query(self, entity, filters=None):
        # Standardized interface across different APIs
        pass
