CharitySense

CharitySense Data API

Canonical REST API for U.S. nonprofit due diligence compiled from public IRS Form 990 filings and official-source profile enrichment. 21 operations across five tags: Profiles (bounded charity page, advertised sections, filings, brand icon, money network, awards, subawards, grantees, funders), Discovery (identity and discovery search, top lists, cohort funders, related-organization discovery, bulk diligence summary), Dataset (health, stats), Assistant (charity question, agent feedback, capabilities, SSE chat stream) and Usage (per-key daily allowance). Public research GETs need no token and are limited to 1,000 requests per UTC day per client; derived reads and every POST are Advanced operations that require a paid bearer token or X-CharitySense-API-Key and return 403 EntitlementRequired anonymously. Responses use UpperCamelCase fields. Published as OpenAPI 3.1.0 at https://data.charitysense.com/openapi.yaml with servers[] https://data.charitysense.com.

  description: >
    Canonical CharitySense API for nonprofit research compiled from the canonical research overlay.
    Research data reads are available without a token and are limited to 1,000
    requests per UTC day per client. Advanced operations require a paid bearer
    token or X-CharitySense-API-Key and consume that key's daily Advanced allowance.
    An authenticated key can read its own current-day usage at `/api/v2/usage`
    without consuming a research-data request.
    Responses use UpperCamelCase fields and return the documented resource
    directly.
