Common Errors & Troubleshooting

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.
