Beginner Tip

Start with a simple name search using the searchTerm query parameter. The free tier returns up to 10 results per request.

Available Data

Use case: Integrate non-profit charity data data into web and mobile applications

Example Response

Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

401 Unauthorized Missing or invalid API key in the request

✓ Add your key as a query parameter: ?apiKey=YOUR_KEY or in the Authorization header as documented.

Empty results array The search term is too specific or includes typos

✓ Try a shorter, broader keyword (e.g. "cancer" instead of "american cancer society foundation").

429 Too Many Requests Exceeded the rate limit for your plan tier

✓ Add a small delay between requests and cache results you fetch frequently.

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
