Overview

Package propublica is the library behind the propublica command line: the HTTP client, request shaping, and the typed data models for the ProPublica Nonprofit Explorer API.

The Client here is the spine every command shares. It sets a real User-Agent, paces requests so a busy session stays polite, and retries the transient failures (429 and 5xx) that any public site throws under load.
