Peecho Python API Docs | dltHub
Build a Peecho-to-database pipeline in Python using dlt with AI Workbench support for Claude Code, Cursor, and Codex.
Last updated:
Peecho is a print‑on‑demand API that enables global dropshipping of printed products. The REST API base URL is https://www.peecho.com/rest/v3/ and Requests require a merchant API key (merchant_api_key) included in the JSON body of each request..
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 Peecho data in under 10 minutes.
What data can I load from Peecho?
Here are some of the endpoints you can load from Peecho:
| Resource | Endpoint | Method | Data selector | Description |
|---|---|---|---|---|
| orders | /order/ | GET | items | Retrieve a list of orders. |
| order_detail | /order/{order_id}/ | GET | Retrieve details of a specific order. | |
| publications | /publications/ | GET | publications | List available publications. |
| offerings | /offerings/ | GET | offerings | List product offerings. |
| async_print | /async/print/ | POST | Submit an asynchronous print request. |
How do I authenticate with the Peecho API?
Authentication is performed by including the merchant API key (merchant_api_key) in the JSON payload of each request; no Authorization header is needed.
1. Get your credentials
- Log in to your Peecho account at https://www.peecho.com.
- Navigate to Settings → API in the main dashboard menu.
- Locate the Merchant API Key (sometimes shown as "merchant_api_key") and copy the value.
- (Optional) Locate the Secret Key if you need to generate SHA‑256 signatures for certain endpoints.
- Store these values securely; they will be used in the dlt
secrets.tomlfile.
2. Add them to .dlt/secrets.toml
[sources.peecho_print_api_source] merchant_api_key = "your_merchant_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 Peecho 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 peecho_print_api_pipeline.py
If everything is configured correctly, you'll see output like this:
Pipeline peecho_print_api_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset peecho_print_api_data The duckdb destination used duckdb:/peecho_print_api.duckdb location to store data Load package 1749667187.541553 is LOADED and contains no failed jobs
Inspect your pipeline and data:
dlt pipeline peecho_print_api_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 orders and publications from the Peecho 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 peecho_print_api_source(merchant_api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://www.peecho.com/rest/v3/", "auth": { "type": "api_key", "api_key": merchant_api_key, }, }, "resources": [ {"name": "orders", "endpoint": {"path": "order/", "data_selector": "items"}}, {"name": "publications", "endpoint": {"path": "publications/", "data_selector": "publications"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="peecho_print_api_pipeline", destination="duckdb", dataset_name="peecho_print_api_data", ) load_info = pipeline.run(peecho_print_api_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("peecho_print_api_pipeline").dataset() sessions_df = data.orders.df() print(sessions_df.head())
SQL (DuckDB example):
SELECT * FROM peecho_print_api_data.orders LIMIT 10;
In a marimo or Jupyter notebook:
import dlt data = dlt.pipeline("peecho_print_api_pipeline").dataset() data.orders.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 Peecho 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.
Troubleshooting
Authentication Errors
- 403 Forbidden – Returned when the
merchant_api_keyis missing, invalid, or does not have permission. Verify the key is correct and included in the request body. - 400 Bad Request – May indicate an incorrectly formatted key or missing required fields.
Rate Limits
- Peecho enforces a request rate limit per merchant. Exceeding the limit returns 429 Too Many Requests with a
Retry-Afterheader indicating when to retry. - Implement exponential back‑off in your pipeline to handle occasional throttling.
Pagination
- List endpoints return a maximum number of records per page (default 50). The response includes a
next_page_urlfield; use this URL to fetch subsequent pages. - Continue fetching until
next_page_urlis null or absent.
Ensure that the API key is valid to avoid 401 Unauthorized errors. Also, verify endpoint paths and parameters to avoid 404 Not Found errors.
