CharitySense

CharitySense is a product of Osci Labs LLC (US) with two public surfaces. charitysense.com is an edge-AI verification platform that plugs into cameras already installed at funded hospitals, schools, water wells and orphanages, processes video on-device, and gives donors, foundations, NGOs and governments live dashboards proving a funded project is actually running. data.charitysense.com is CharitySense Data, an agent-ready nonprofit due-diligence API over public IRS Form 990 filings for about 2.2 million U.S. nonprofits: charity search, bounded profile pages with lazily fetched sections, filing history, money-network and grant-flow evidence, related-organization discovery, dataset statistics and a paid assistant. It is a 21-operation OpenAPI 3.1.0 contract at https://data.charitysense.com/openapi.yaml; research reads need no key (1,000 per UTC day), Advanced operations need a paid key. The host also serves an RFC 9727 API catalog, an A2A-shaped agent card, ai-plugin.json and llms.txt.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/charitysense-com: open an issue to ask a question, or submit a pull request to add artifacts.
