Foundations and boundaries
We researched GivingTuesday's MIT-licensed Form 990 XML mapper, ProPublica's Nonprofit Explorer API, RPublica and CharityLens. This initial release uses original summaries and source links, and includes a small original adapter for live registry lookup. We do not mirror ProPublica's raw dataset or copy unlicensed code. The source and license record explains the choices.
Registry lookup is not impact evaluation
US tax-filing records can identify entities and describe reported finances. Registration, a filing, an overhead ratio or a returned API result cannot establish systemic impact. The optional registry tool runs locally and keeps raw responses out of the public dataset.
Reproducible review
Each profile records source URLs, rationales, review date, selection reason and limitations. Validation rejects missing provenance, invalid scores and accidental publication of credentials. Changes can be proposed through GitHub issues and reviewed before publication.
