Load Bittensor data to DuckDB

Taostats is a platform providing access to Bittensor blockchain data, subnet analytics, and staking operations via a REST API. Everything needed to build a working Bittensor → 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 Bittensor 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 Bittensor 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 Bittensor 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.

Bittensor API at a glance

These values come from the Bittensor API reference — the authoritative source if anything here looks out of date.

---

How do I authenticate with the Bittensor API?

The API authenticates requests using a project-specific API key provided in the request headers.

1. Get your credentials

To obtain API credentials for the Taostats-managed Bittensor REST API, follow these steps: 1. Navigate to the Taostats dashboard at https://dash.taostats.io and sign in. 2. Create an organization by providing the required name and description. 3. Within your organization, create a new project. 4. Navigate to the Project's API Keys section and select 'Create API key'. 5. Copy the generated key immediately and store it in a secure location, as it will not be displayed again.

2. Add them to .dlt/secrets.toml

Copy
[sources.bittensor_source]
api_key = "your_taostats_api_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 Bittensor data can I load into DuckDB?

These are the Bittensor endpoints dlt can load into DuckDB:

---

How do I load only new Bittensor records?

The Bittensor 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": "pallets", "endpoint": {
    "path": "pallets",
    # 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 Bittensor pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading api_status and blocks from the Bittensor API into DuckDB:

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

@dlt.source
def bittensor_source(api_key=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://management-api.taostats.io/api/v1",
            "auth": {"type": "bearer", "token": api_key},
        },
        "resources": [
            {"name": "pallets", "endpoint": {"path": "pallets"}},
            {"name": "events", "endpoint": {"path": "events"}}
        ],
    }
    yield from rest_api_resources(config)


def load_bittensor_to_duckdb() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="bittensor_pipeline",
        destination="duckdb",
        dataset_name="bittensor_data",
    )
    load_info = pipeline.run(bittensor_source())
    print(load_info)


if __name__ == "__main__":
    load_bittensor_to_duckdb()

Run it with python bittensor_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 Bittensor 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("bittensor_pipeline").dataset()
df = data.pallets.df()
print(df.head())

SQL:

Copy
SELECT * FROM bittensor_data.pallets LIMIT 10;

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

How do I deploy the Bittensor 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 Bittensor 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 Bittensor 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.
