Parasail Python API Docs | dltHub
Build a Parasail-to-database pipeline in Python using dlt with AI Workbench support for Claude Code, Cursor, and Codex.
Last updated:
Parasail offers a direct replacement for OpenAI's batch API, supporting the same file formats and processing large-scale AI tasks efficiently. The API reference provides detailed documentation for its batch processing capabilities. Parasail's dedicated endpoint management API allows for deployment and management of dedicated services. The REST API base URL is https://api.parasail.io/v1 and All requests require a Bearer API key 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 pip install "dlt[workspace]" and start loading Parasail data in under 10 minutes.
What data can I load from Parasail?
Here are some of the endpoints you can load from Parasail:
| Resource | Endpoint | Method | Data selector | Description |
|---|---|---|---|---|
| models | /v1/models | GET | data | List available models (OpenAI-compatible models). |
| dedicated_devices | /dedicated/devices | GET | (top-level array) | Retrieve supported hardware/device configs for a model. |
| dedicated_support | /dedicated/support | GET | (object) | Check whether a model is supported; response contains supported (bool) and errorMessage. |
| dedicated_deployments | /dedicated/deployments | GET | (top-level array) | Retrieve all dedicated deployments. |
| dedicated_deployment | /dedicated/deployments/{deployment_id} | GET | (object) | Retrieve a single deployment; status is at status.status and externalAlias is the OpenAI-compatible model identifier. |
| chat_completions | /v1/chat/completions | POST | (object) | OpenAI-compatible chat completion (used for inference against serverless or externalAlias models). |
| batch_submit | /v1/batch | POST | (batch output is JSONL per-line objects) | Submit a batch job (OpenAI Batch API compatibility). |
How do I authenticate with the Parasail API?
Parasail uses a single API key (Bearer token). Include header: Authorization: Bearer <PARASAIL_API_KEY>. For some control/management endpoints the control base is https://api.parasail.io/api/v1 and uses the same Bearer header.
1. Get your credentials
- Sign in to the Parasail SaaS dashboard (https://www.saas.parasail.io). 2) Open the Keys page (https://www.saas.parasail.io/keys) or Profile -> API Keys. 3) Create a new API key; copy it immediately (it is shown only once). 4) Store as environment variable PARASAIL_API_KEY or in your dlt secrets.toml.
2. Add them to .dlt/secrets.toml
[sources.parasail_source] api_key = "your_parasail_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 Parasail 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 parasail_pipeline.py
If everything is configured correctly, you'll see output like this:
Pipeline parasail_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset parasail_data The duckdb destination used duckdb:/parasail.duckdb location to store data Load package 1749667187.541553 is LOADED and contains no failed jobs
Inspect your pipeline and data:
dlt pipeline parasail_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 models and dedicated_deployments from the Parasail 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 parasail_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.parasail.io/v1", "auth": { "type": "bearer", "token": api_key, }, }, "resources": [ {"name": "models", "endpoint": {"path": "v1/models", "data_selector": "data"}}, {"name": "dedicated_deployments", "endpoint": {"path": "dedicated/deployments"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="parasail_pipeline", destination="duckdb", dataset_name="parasail_data", ) load_info = pipeline.run(parasail_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("parasail_pipeline").dataset() sessions_df = data.models.df() print(sessions_df.head())
SQL (DuckDB example):
SELECT * FROM parasail_data.models LIMIT 10;
In a marimo or Jupyter notebook:
import dlt data = dlt.pipeline("parasail_pipeline").dataset() data.models.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 Parasail 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.
