pbn-client 0.1.0

Framework-independent client for the Polish Bibliography Network API

pbn-client

pbn-client is a framework-independent Python client for communication with the Polish Bibliography Network (PBN) API. It provides HTTP authentication, pagination, dictionary and publication endpoints, and institution-profile statement operations.

The package does not depend on Django or an external error-reporting service. Projects that persist downloaded PBN data in Django should use the companion django-pbn-client package.

Installation

pip install pbn-client

Python 3.10 through 3.14 is supported.

Basic usage

from pbn_client import PBNClient, RequestsTransport

transport = RequestsTransport(
    app_id="application-id",
    app_token="application-token",
    base_url="https://pbn-micro-alpha.opi.org.pl",
    user_token="user-token",
    timeout=(30, 120),
)
client = PBNClient(transport)

languages = list(client.get_languages())

Credentials should normally be supplied explicitly. The interactive command helpers also understand PBN_CLIENT_APP_ID, PBN_CLIENT_APP_TOKEN, PBN_CLIENT_BASE_URL, PBN_CLIENT_USER_TOKEN, and PBN_CLIENT_HTTP_TIMEOUT. A timeout may be a single number or a connect,read pair.

Error reporting

The standalone default reporter is a no-op. An application can inject any object implementing ErrorReporter when it constructs a transport:

import rollbar

from pbn_client import RequestsTransport

transport = RequestsTransport(
    "application-id",
    "application-token",
    "https://pbn-micro-alpha.opi.org.pl",
    reporter=rollbar,
)

The reporter receives only scrubbed diagnostic metadata. Response bodies and authentication header values are not sent to it. LoggingReporter, NullReporter, and set_default_reporter() are also available for applications that prefer a process-wide policy.
