Airflow provider for Cian.ru Builder API — collect calls and chats statistics.

Installation

pip install airflow-provider-cian

Requirements: Python 3.10+, Apache Airflow 2.9.1–2.x.

Connection Setup

Create an HTTP connection in Airflow (Admin → Connections):

Field	Value
Connection Id	cian_default (or any name)
Connection Type	HTTP
Host	https://public-api.cian.ru
Password	Bearer token from your Cian Builder cabinet

The provider reads conn.host as base URL and conn.password as Bearer token.

Operator Parameters

CianBuilderReportsOperator:

Parameter	Type	Default	Description
cian_conn_id	str	cian_default	Airflow connection ID
date	str	required	Collection date, YYYY-MM-DD. Supports {{ ds }} template
base_dir	str	/tmp/cian	Base directory for output files
output_format	str	json	json (JSONL) or csv

The operator returns the output file path via return_value XCom.

Output file path: {base_dir}/{safe_run_id}/{date}.{ext}

Output Schema (18 fields)

id, newbuilding_id, newbuilding_name, date, datetime, action_type, searcher_phone, searcher_ct_phone, builder_user_ct_phone, builder_user_phone, builder_sip_uri, call_duration, tariff_price, auction_bet, cashback_spent, billing_price, has_claim, is_targeted

• date — date extracted in Moscow time (YYYY-MM-DD), useful for partitioning
• datetime — original API datetime with explicit Moscow offset (YYYY-MM-DDTHH:MM:SS+03:00)
• is_targeted is computed: billing_price > 0.

Example DAG

from datetime import date, timedelta
from airflow.decorators import dag, task
from airflow.operators.python import PythonOperator
from airflow_provider_cian.operators.builder_reports import CianBuilderReportsOperator
import os

@dag(schedule=None, catchup=False, max_active_tasks=3)
def cian_reports():
    @task
    def get_dates():
        yesterday = date.today() - timedelta(days=1)
        return [(yesterday - timedelta(days=i)).isoformat() for i in range(7)]

    dates = get_dates()

    collect = CianBuilderReportsOperator.partial(
        task_id="collect",
        cian_conn_id="cian_default",
        base_dir="/tmp/cian",
        output_format="json",
    ).expand(date=dates)

    # Add upload here, e.g. LocalFilesystemToS3Operator.partial(...).expand(filename=collect)

    def cleanup(ti, **ctx):
        for path in (ti.xcom_pull(task_ids="collect") or []):
            if path and os.path.exists(path):
                os.remove(path)

    collect >> PythonOperator(task_id="cleanup", python_callable=cleanup, trigger_rule="all_done")

cian_reports()

Rate Limiting

The API limit is ≤10 req/s per token (per Cian account). The hook adds a 100ms sleep before each request. max_active_tasks=3 on the DAG level provides additional safety margin.

If multiple clients share the same IP and you still get 429 errors, create an Airflow Pool:

airflow pools set cian_api 5 "Cian API rate limit pool"

Then pass pool="cian_api" to CianBuilderReportsOperator.partial(...).

Retry Behaviour

On HTTP 429 or 5xx: exponential backoff — 1s, 2s, 4s (3 attempts total), then AirflowException.
