Load BtcTurk data to DuckDB

BtcTurk is a cryptocurrency exchange platform that provides public and private REST APIs for market data and account management operations. Everything needed to build a working BtcTurk → DuckDB pipeline is on this page: the API's base URL, authentication, endpoints, pagination and incremental field — plus a prompt that hands the whole job to your coding agent.

Build your BtcTurk to DuckDB pipeline

Paste this prompt into Claude, Codex, or Cursor. The agent does the rest.

PromptCopy prompt
Run uvx dlthub-init@latest to build a pipeline from BtcTurk to DuckDB and run it on dltHub

That scaffolds a dltHub workspace and installs the dltHub AI harness — the project rules, the secrets-management skill, and the dlt MCP server your agent needs to work safely. From there it reads the BtcTurk API, proposes the endpoints to load, then writes, runs and validates the pipeline while you review rather than type. Credentials are inspected through MCP tools, so your agent never reads secrets.toml itself. How the LLM-native workflow works →

Prefer to write it yourself? Every fact the agent uses is below.

BtcTurk API at a glance

These values come from the BtcTurk API reference — the authoritative source if anything here looks out of date.

---

How do I authenticate with the BtcTurk API?

Authentication for private endpoints requires HMAC-SHA256 signing of a message (API Public Key + timestamp in milliseconds) using your Secret Key. The signature and timestamp must be passed in the 'X-Signature' and 'X-Stamp' headers respectively, alongside your public key in the 'X-PCK' header.

1. Get your credentials

To obtain API credentials for BtcTurk, log in to your BtcTurk PRO account, navigate to the Account menu, and select API Access. On the API Access page, click the button to create a new API key. You will be prompted to select desired permissions (such as account, trade, or WebSocket). After submitting the form, save both the generated Public API Key and the Private Secret Key. Keep the Secret Key secure, as it is required for computing the HMAC signature for private API requests.

2. Add them to .dlt/secrets.toml

Copy
[sources.btcturk_source]
api_key = "your_public_key_here"
api_secret = "your_private_key_here"

dlt reads this file automatically at runtime. With the harness, the setup-secrets skill prompts you for the values and never handles the raw credential in chat. For production, see setting up credentials with dlt.

What BtcTurk data can I load into DuckDB?

These are the BtcTurk endpoints dlt can load into DuckDB:

---

How do I load only new BtcTurk records?

The BtcTurk API reference does not document a timestamp or sequence field for these endpoints, so there is nothing to advertise here as verified. Pick a field from the endpoints table above that increases with every write, then set it as the cursor_path.

Copy
{"name": "all_orders", "endpoint": {
    "path": "api/v1/allOrders",
    # Replace with a field that increases on every write.
    "incremental": {"cursor_path": "REPLACE_ME", "initial_value": "2024-01-01T00:00:00Z"},
}}

On the first run dlt loads everything from initial_value; on every run after that it requests only what changed and appends with write_disposition="merge" if you set a primary key. See incremental loading.

What does the generated BtcTurk pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading balances and allOrders from the BtcTurk API into DuckDB:

Copy
import dlt
from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources

@dlt.source
def btcturk_source(api_key=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://api.btcturk.com",
            "auth": {"type": "api_key", "api_key": api_key},
        },
        "resources": [
            {"name": "all_orders", "endpoint": {"path": "api/v1/allOrders", "data_selector": "data"}},
            {"name": "crypto_transactions", "endpoint": {"path": "api/v1/users/transactions/crypto", "data_selector": "data"}}
        ],
    }
    yield from rest_api_resources(config)


def load_btcturk_to_duckdb() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="btcturk_pipeline",
        destination="duckdb",
        dataset_name="btcturk_data",
    )
    load_info = pipeline.run(btcturk_source())
    print(load_info)


if __name__ == "__main__":
    load_btcturk_to_duckdb()

Run it with python btcturk_pipeline.py. The agent iterates on this until it loads cleanly — you review and approve, rather than write it from scratch.

How do I query BtcTurk data in DuckDB?

dlt creates one table per resource. Query the loaded data with Python or SQL — or ask your agent to, through the MCP server's execute_sql_query tool.

Python (pandas DataFrame):

Copy
import dlt

data = dlt.pipeline("btcturk_pipeline").dataset()
df = data.orderbook.df()
print(df.head())

SQL:

Copy
SELECT * FROM btcturk_data.orderbook LIMIT 10;

See querying your data with dataset and exploring it in marimo notebooks.

---

How do I deploy the BtcTurk to DuckDB pipeline in production?

The pipeline runs locally, which is ideal for prototyping and one-off analysis. When you need it on a schedule, monitored on every load, and shared with your team, deploy the same dlt code on the dltHub platform — no infrastructure to maintain. The prompt above already ends with "run it on dltHub", so your agent can take it there directly.

• Deploy & schedule — run the pipeline as a managed job with automatic retries.
• Monitor — observable job queues, alerting, and load metrics for every run.
• Transform — promote raw BtcTurk loads into governed, documented models.
• Visualize & share — explore data in notebooks and publish live dashboards instead of static screenshots.

What other destinations can I load BtcTurk data to?

dlt loads into any of these — only the destination argument changes:

Set dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. On the dltHub platform the same pipeline runs against a managed Iceberg lakehouse. See the full destinations list.
