Loro Python API Docs | dltHub

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

Last updated:

Loro is a high-performance CRDT library for real-time collaboration. It provides JavaScript/TypeScript bindings and Rust API documentation. The API supports container management and conflict-free replication. The REST API base URL is https://api.lorotemplates.com and All requests require an API key in the X-API-Key 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 pip install "dlt[workspace]" and start loading Loro data in under 10 minutes.


What data can I load from Loro?

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

ResourceEndpointMethodData selectorDescription
templates/api/templatesGETReturns a top‑level JSON array of template objects.
template_detail/api/templates/{id}GETReturns a JSON object representing a single template.
render_template/api/templates/renderPOSTRenders a template with supplied data; response includes success flag and rendered result.

How do I authenticate with the Loro API?

The API uses an API key passed in the X-API-Key request header.

1. Get your credentials

  1. Visit https://lorotemplates.com and sign up for an account.
  2. Log in to the dashboard.
  3. Navigate to the "API Keys" or "Integrations" section.
  4. Click "Create New API Key" and give it a descriptive name.
  5. Copy the generated key; you will use it as the value for the X-API-Key header.
  6. Store the key securely (e.g., in dlt's secrets.toml).

2. Add them to .dlt/secrets.toml

[sources.loro_source] api_key = "your_api_key_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 venv && source .venv/bin/activate uv pip install "dlt[workspace]"

1. Install the dlt AI Workbench:

dlt 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:

dlt ai toolkit rest-api-pipeline install

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 Loro 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:

python loro_pipeline.py

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

Pipeline loro_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset loro_data The duckdb destination used duckdb:/loro.duckdb location to store data Load package 1749667187.541553 is LOADED and contains no failed jobs

Inspect your pipeline and data:

dlt pipeline loro_pipeline 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 templates and template_detail from the Loro 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 loro_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.lorotemplates.com", "auth": { "type": "api_key", "api_key": api_key, }, }, "resources": [ {"name": "templates", "endpoint": {"path": "api/templates"}}, {"name": "template_detail", "endpoint": {"path": "api/templates/{id}"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="loro_pipeline", destination="duckdb", dataset_name="loro_data", ) load_info = pipeline.run(loro_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("loro_pipeline").dataset() sessions_df = data.templates.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM loro_data.templates LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("loro_pipeline").dataset() data.templates.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 Loro 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.
