dpp-sdk 0.1.1

Python SDK for interacting with Digital Product Passport (DPP) System Infrastructure

dpp-sdk (Python)

Python SDK for Digital Product Passports (DPP), built on Pydantic v2.

It provides typed models, validation, and JSON transport for digital product passports, plus HTTP clients for the two DPP backend APIs:

• the DPP registry — hosted by the European Commission, and
• the DPP repository — hosted by economic operators or service providers.

Both APIs conform to the draft standardisation documents published by CEN/CENELEC.

Install

pip install dpp-sdk

Requires Python 3.11+.

Quickstart

from dpp_sdk import Dpp4Fun, from_json, to_json, validate_dpp4fun

# Parse an incoming passport (accepts both flat and nested JSON shapes)
dpp = from_json(raw_json)

# Validate against the DPP rule set (raises on violations)
validate_dpp4fun(dpp)

# Serialize back to the flattened wire JSON
payload = to_json(dpp)

The httpx-based clients for the registry and repository APIs live in dpp_sdk.clients:

from dpp_sdk.clients import DppRepoClient, DppRegistryClient
