product-dl 0.0.0.dev0

Youtube-DL but for product pages.

product-dl / product-ui / list-dl

This repository contains three packages:

• product-dl — "youtube-dl but for product pages". Given a URL it detects the right provider, scrapes the product page, and returns a normalised ParsedProduct as JSON. Exposes a CLI and a FastAPI JSON API (default port 7001).
• product-ui — UI companion. Calls the product-dl API, persists crawls to disk, and serves a Bootstrap web interface for browsing and triggering crawls (default port 7002).
• list-dl — Scrapes order histories and wishlists on demand. Like product-dl but for lists (Amazon orders, public wishlists, etc.). Returns structured Order objects. Exposes a CLI and a FastAPI JSON API (default port 7003).

Install

pip install product-dl        # or: uv add product-dl

CLI

# Fetch a product page and print JSON
product-dl fetch <url>

# Extra options
product-dl fetch <url> \
  --headers '{"Accept-Language": "de-DE"}' \
  --cookies path/to/cookies.json \
  --data-dir ./data \
  --save-example my-label \
  --indent 4

# Parse a locally saved HTML file
product-dl parse amazon path/to/product.html --url https://www.amazon.de/dp/B08N5WRWNW

# Start the API server
product-dl serve --host 0.0.0.0 --port 7001

# Export the OpenAPI schema (default: YAML)
product-dl openapi
product-dl openapi --format json --output ./openapi.json

# List discovered providers
product-dl providers
product-dl providers --format json

--data-dir / PRODUCT_DL_DATA_DIR

When set, the CLI (and API server via env var) will:

• Auto-load <data-dir>/cookies/<provider>.json and <data-dir>/headers/<provider>.json before each request.
• Detect Akamai CDN bot-detection and switch to httpx-curl-cffi (Chrome TLS impersonation) automatically:
  • If any Akamai cookie key (ak_bmsc, _abck, bm_sz, bm_sv, RT) is present in the merged cookies.
  • Or if a 503 response body contains Akamai signatures (errors.edgesuite.net / Zero size object).
• Save Akamai cookies received in curl_cffi responses back to <data-dir>/cookies/<provider>.json for reuse.

# CLI
product-dl fetch https://www.ebay.de/itm/123 --data-dir ./data

# env var (also used by the API server)
export PRODUCT_DL_DATA_DIR=./data
product-dl fetch https://www.ebay.de/itm/123

API

product-dl serve          # http://127.0.0.1:7001
# or
uvicorn product_dl.api.app:app

GET  /fetch?url=<url>
POST /fetch  {"url": "<url>"}

Both return a ParsedProduct JSON object. PRODUCT_DL_DATA_DIR is read server-side from the environment — it is not an API parameter.

Latest generated API descriptions are published to the repository gh-pages branch as:

• product_dl/openapi.json
• product_dl/openapi.yml
• product_dl/providers.json
• list_dl/openapi.json
• list_dl/openapi.yml
• list_dl/providers.json
• list_dl/login_providers.json
• catalog/commit_map.json

Adding a provider

Built-in — create src/product_dl/providers/<name>/__init__.py exposing:

PROVIDER_NAME: str
def can_provide(url: str, parsed_url: ParseResult) -> T | None: ...
async def provide(
    url: str,
    parsed_url: ParseResult,
    provide_check: T,
    *,
    save_files: SaveFiles | None = None,
    local_html: str | None = None,
    extra_headers: dict[str, str] | None = None,
    extra_cookies: dict[str, str] | None = None,
    data_dir: Path | None = None,
) -> ParsedProduct: ...

Auto-discovered via pkgutil — no pyproject.toml changes needed. Use product_dl.utils.http.fetch_html for HTTP requests so Akamai handling and cookie persistence work automatically.

Third-party — publish a package with a product_dl.providers entry point. No changes to this project needed.

list-dl

Scrapes order histories and wishlists from e-commerce sites on demand. Mirror of product-dl architecture but for lists instead of individual products.

Supported providers

Provider	Status	Notes
amazon_orders	Active	Amazon order history scraper (pagination, delivery states, items). Requires authentication.

Install

# Bundled with product-dl
pip install product-dl

Login & Credentials

list-dl uses a pluggable login provider system. Each provider handles site-specific authentication and stores credentials locally for reuse.

Login Command

# Interactive login (prompts for password)
list-dl login amazon --username [e-mail]

# Non-interactive login (provide all credentials)
list-dl login amazon --username [e-mail] --password mypassword

# Login to a specific flavor (e.g., amazon.de)
list-dl login amazon --flavor de --username [e-mail] --password mypassword

Credentials are stored in ./crawl_data/list_dl/login/{site}/login.json.

Environment Variables

Credentials can be loaded from environment variables. Precedence (highest to lowest):

1. CLI arguments (--username, --password, --code)
2. LOGIN_{SITE}_{FLAVOR}_{FIELD} (e.g., LOGIN_AMAZON_DE_USERNAME)
3. LOGIN_{SITE}_{FIELD} (e.g., LOGIN_AMAZON_USERNAME)
4. Generic field name (e.g., USERNAME, PASSWORD, CODE) — Warning: generic USERNAME defaults to the Linux user if not explicitly set

# Load credentials from environment
export LOGIN_AMAZON_USERNAME=[e-mail]
export LOGIN_AMAZON_PASSWORD=mypassword
list-dl login amazon

# Or with flavor
export LOGIN_AMAZON_DE_USERNAME=[e-mail]
export LOGIN_AMAZON_DE_PASSWORD=mypassword
list-dl login amazon --flavor de

# Non-interactive (no TTY)
echo mypassword | list-dl login amazon --username [e-mail]

.env File Support

The login command reads from .env.local (highest priority) and .env files:

# .env.local (excluded from git)
LOGIN_AMAZON_USERNAME=[e-mail]
LOGIN_AMAZON_PASSWORD=mypassword

Then:

list-dl login amazon

Two-Factor Authentication (2FA / TOTP)

When a site requires 2FA, list-dl supports three workflows:

Workflow 1: Single command (all credentials at once)

list-dl login amazon --username [e-mail] --password mypass --code 123456

Automatically chains login → 2FA → stores final credentials.

Workflow 2: Two separate commands

# First run: login, save partial credentials with TOTP form
list-dl login amazon --username [e-mail] --password mypass
# Output: ⚠ TOTP code required. Run: list-dl login amazon --code <code> --flavor com

# Second run: submit 2FA code using stored credentials
list-dl login amazon --code 123456

Workflow 3: Interactive mode (detects TTY)

# Prompts for missing credentials, including 2FA code when required
list-dl login amazon
# Email address: [e-mail]
# Password: (hidden input)
# 2FA Code (6 digits): 123456

2FA codes can also be provided via the CODE environment variable:

export CODE=123456
list-dl login amazon

CLI

# Fetch orders from Amazon (requires prior login)
list-dl fetch amazon orders --mode my_orders

# Fetch a public wishlist (no login required)
list-dl fetch amazon wishlist --url https://www.amazon.de/hz/wishlist/ls/ABC123

# Fetch from a different flavor (amazon.de)
list-dl fetch amazon orders --flavor de --mode my_orders

# Start the API server
list-dl serve --host 0.0.0.0 --port 7003

# Export the OpenAPI schema (default: YAML)
list-dl openapi
list-dl openapi --format json --output ./openapi.json

# List discovered providers
list-dl providers
list-dl providers --format json
list-dl login-providers --format json

API

list-dl serve          # http://127.0.0.1:7003

Credentials can be supplied in the request:

POST /fetch
{
  "site": "amazon",
  "category": "orders",
  "mode": "my_orders",
  "credentials": {"username": "...", "password": "...", "cookies": {...}},
  "fetch_details": true
}

Or, if already logged in, credentials are auto-loaded from disk:

curl -X POST http://localhost:7003/fetch \
  -H "Content-Type: application/json" \
  -d '{"site": "amazon", "category": "orders", "mode": "my_orders"}'

Adding a provider

Built-in — create src/list_dl/providers/<name>/__init__.py with:

from list_dl.providers.base import ListProviderBase, register

@register
class MyOrdersProvider(ListProviderBase[CHECK_TYPE, MyOrderExtra, MyItemExtra]):
    PROVIDER_NAME = "my_orders"

    @classmethod
    def can(cls, provider_name, mode, url) -> CHECK_TYPE | None:
        """Return truthy if this provider can handle the request."""
        ...

    async def init(self) -> None:
        """Initialize (e.g., open HTTP client)."""
        ...

    async def fetch_orders(self) -> AsyncIterator[Order]:
        """Yield Order objects."""
        ...

    async def fetch_order_detail(self, order: Order) -> Order:
        """Enrich order with detail page data (items, summary, payment)."""
        return order  # or enriched order

Auto-discovered via pkgutil — no pyproject.toml changes needed. Use httpx with optional Akamai bypass via curl_cffi (same pattern as product-dl).
