IRS nonprofit data is powerful, but hard to use

Raw IRS charity datasets are large, code-heavy, and difficult to query without preprocessing, metadata lookups, filtering logic, and location enrichment.

CharityQuery turns that data into a fast, predictable API with developer-friendly filtering, field selection, enriched code responses, and nearby nonprofit search.

Nearby nonprofit search

Find nonprofits within a radius using ZIP codes or coordinates, with distance included in each result.

Powerful filtering

Filter by state, ZIP, NTEE codes, IRS classifications, deductibility, financial ranges, geocode status, and more.

Field selection

Request only the fields your app needs for smaller responses and cleaner frontend data handling.

Enriched IRS codes

Many coded fields return readable descriptions, so your app does not need separate lookup tables.

Request

fetch("https://api.charityquery.com/nearby?origin_zip=28403&radius=10&fields=ein,name,city,state,ntee_group,distance_miles,lat,lng&limit=3", {
  headers: {
    "x-api-key": "YOUR_API_KEY"
