TTAPI Python API Docs | dltHub

Build a TTAPI-to-database pipeline in Python using dlt with AI harness support for Claude Code, Cursor, and Codex.

Last updated:

TTAPI provides a suite of AI-powered RESTful services for music, image, and language processing tasks. The REST API base URL is https://api.ttapi.io and All requests require an API key passed in the request 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 TTAPI data in under 10 minutes.


What data can I load from TTAPI?

Here are some of the endpoints you can load from TTAPI:

ResourceEndpointMethodData selectorDescription
midjourney_imaginemidjourney/v1/imaginePOSTdataGenerate images from a prompt
midjourney_fetchmidjourney/v1/fetchGETdataFetch job result
luma_generateluma/v1/generationsPOSTdataGenerate video job
luma_fetchluma/v1/fetchGETdataFetch video job result
llm_chat_completionsv1/chat/completionsPOSTChat/completion endpoint

How do I authenticate with the TTAPI API?

All requests must include the API key in the request header named 'TT-API-KEY'.

1. Get your credentials

To obtain credentials for the Trading Technologies (TT) REST API, follow these steps in the TT platform: 1. Ensure your company administrator has enabled the 'Can create TT Rest API key' permission for your user account. 2. Log into the TT Platform Setup application (use the UAT environment for development or Live for production). 3. Navigate to the 'Users' section, select your user, and go to the 'App Keys' tab. 4. Click 'New' to create a new application key. 5. Select 'TT REST API' as the Application Key Type, choose a usage plan, and click 'Create'. 6. Copy the generated application key value (displayed in the 'Value' column) and the application secret (displayed in the 'Secret' field or via 'Copy Secret to Clipboard'). You will need both to generate an authentication token.

2. Add them to .dlt/secrets.toml

[sources.ttapi_source] tt_api_key = "your_application_key_here" tt_api_secret = "your_application_secret_here"

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 TTAPI 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 ttapi_pipeline.py

If everything is configured correctly, you'll see output like this:

Pipeline ttapi_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset ttapi_data The duckdb destination used duckdb:/ttapi.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 /token and / (base API endpoints) from the TTAPI 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 ttapi_source(tt_api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.ttapi.io", "auth": {"type": "api_key", "api_key": tt_api_key, "name": "TT-API-KEY", "location": "header"}, }, "resources": [ {"name": "midjourney_imagine", "endpoint": {"path": "midjourney/v1/imagine", "data_selector": "data"}}, {"name": "midjourney_fetch", "endpoint": {"path": "midjourney/v1/fetch", "data_selector": "data"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="ttapi_pipeline", destination="duckdb", dataset_name="ttapi_data", ) load_info = pipeline.run(ttapi_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("ttapi_pipeline").dataset() sessions_df = data.midjourney_fetch.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM ttapi_data.midjourney_fetch LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("ttapi_pipeline").dataset() data.midjourney_fetch.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 TTAPI data to?

dlt supports loading into any of these destinations — only the destination parameter changes:

DestinationExample 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.
