Cinchy Python API Docs | dltHub
Build a Cinchy-to-database pipeline in Python using dlt with AI harness support for Claude Code, Cursor, and Codex.
Last updated:
Cinchy is an enterprise data platform that provides a REST API for executing CQL queries, accessing saved queries, health checks, jobs, and secrets management. The REST API base URL is https://cinchy.net and all requests require a Bearer token in the Authorization header.
dlt is an open-source Python library that handles authentication, pagination, and schema evolution automatically. dlthub provides AI context files that enable code assistants to generate production-ready pipelines. Install with uv add "dlt[hub]" and start loading Cinchy data in under 10 minutes.
What data can I load from Cinchy?
Here are some of the endpoints you can load from Cinchy:
| Resource | Endpoint | Method | Data selector | Description |
|---|---|---|---|---|
| saved_queries | /api/v1.0/[Domain]/[QueryName] | GET | Executes a saved query and returns data via REST API | |
| execute_cql | /API/ExecuteCQL | POST | Executes Cinchy Query Language directly | |
| jobs | /api/jobs | POST | Triggers a configured batch data sync job | |
| healthcheck | /healthcheck | GET | Standard system health check endpoint | |
| token | /identity/connect/token | POST | Retrieves an OAuth 2.0 bearer access token |
How do I authenticate with the Cinchy API?
All requests require an 'Authorization' header containing the token prefixed with the word 'Bearer' (e.g., 'Bearer ').
1. Get your credentials
To obtain credentials for the Cinchy REST API, you must first register a client within the Cinchy platform to receive a 'client_id' and 'client_secret'. Once you have these, you can obtain a Bearer access token by making a POST request to the identity endpoint (typically 'https:///identity/connect/token'). The request body must be form-urlencoded and include your 'client_id', 'client_secret', 'username', 'password', and 'grant_type=password'. Alternatively, for Cinchy v5.5+, you may generate a 'Personal Access Token' (PAT) directly through the Cinchy user interface.
2. Add them to .dlt/secrets.toml
[sources.cinchy_source] cinchy_client_id = "your_client_id_here" cinchy_client_secret = "your_client_secret_here" cinchy_username = "your_username_here" cinchy_password = "your_password_here" cinchy_base_url = "https://your-cinchy-instance.com"
dlt reads this automatically at runtime — never hardcode tokens in your pipeline script. For production environments, see setting up credentials with dlt for environment variable and vault-based options.
How do I set up and run the pipeline?
Set up a virtual environment and install dlt:
uv init uv add "dlt[hub]"
1. Install the dlt AI harness:
uv run dlthub ai init --agent <your-agent> # <agent>: claude | cursor | codex
This installs project rules, a secrets management skill, appropriate ignore files, and configures the dlt MCP server for your agent. Learn more →
2. Install the rest-api-pipeline toolkit:
uv run dlthub ai toolkit install rest-api-pipeline
This loads the skills and context about dlt the agent uses to build the pipeline iteratively, efficiently, and safely. The agent uses MCP tools to inspect credentials — it never needs to read your secrets.toml directly. Learn more →
3. Start LLM-assisted coding:
Use /find-source to load data from the Cinchy API into DuckDB.
The rest-api-pipeline toolkit takes over from here — it reads relevant API documentation, presents you with options for which endpoints to load, and follows a structured workflow to scaffold, debug, and validate the pipeline step by step.
4. Run the pipeline:
uv run python cinchy_pipeline.py
If everything is configured correctly, you'll see output like this:
Pipeline cinchy_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset cinchy_data The duckdb destination used duckdb:/cinchy.duckdb location to store data Load package 1749667187.541553 is LOADED and contains no failed jobs
Inspect your pipeline and data:
uv run dlthub show
This opens the Pipeline Dashboard where you can verify pipeline state, load metrics, schema (tables, columns, types), and query the loaded data directly.
Python pipeline example
This example loads /identity/connect/token and /api/v1.0/ (for accessing saved query APIs) from the Cinchy API into DuckDB. It mirrors the endpoint and data selector configuration from the table above:
import dlt from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources @dlt.source def cinchy_source(access_token=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://cinchy.net", "auth": {"type": "bearer", "token": access_token}, }, "resources": [ {"name": "saved_queries", "endpoint": {"path": "api/v1.0/[Domain]/[QueryName]"}}, {"name": "token", "endpoint": {"path": "identity/connect/token"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="cinchy_pipeline", destination="duckdb", dataset_name="cinchy_data", ) load_info = pipeline.run(cinchy_source()) print(load_info)
To add more endpoints, append entries from the resource table to the "resources" list using the same name, path, and data_selector pattern.
How do I query the loaded data?
Once the pipeline runs, dlt creates one table per resource. You can query with Python or SQL.
Python (pandas DataFrame):
import dlt data = dlt.pipeline("cinchy_pipeline").dataset() sessions_df = data.saved_queries.df() print(sessions_df.head())
SQL (DuckDB example):
SELECT * FROM cinchy_data.saved_queries LIMIT 10;
In a marimo or Jupyter notebook:
import dlt data = dlt.pipeline("cinchy_pipeline").dataset() data.saved_queries.df().head()
See how to explore your data in marimo Notebooks and how to query your data in Python with dataset.
What destinations can I load Cinchy data to?
dlt supports loading into any of these destinations — only the destination parameter changes:
| Destination | Example value |
|---|---|
| DuckDB (local, default) | "duckdb" |
| PostgreSQL | "postgres" |
| BigQuery | "bigquery" |
| Snowflake | "snowflake" |
| Redshift | "redshift" |
| Databricks | "databricks" |
| Filesystem (S3, GCS, Azure) | "filesystem" |
Change the destination in dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. See the full destinations list.
