Overview

The Humanitarian Data Exchange (HDX) API provides programmatic access to thousands of open humanitarian datasets covering crises, conflicts, disasters, and development indicators worldwide, shared by UN agencies, NGOs, and governments. Registration is free and an API key is available through your HDX account. It is a powerful resource for researchers and developers working on humanitarian or global development projects.

Beginner Tip

Start by searching datasets with the /api/3/action/package_search?q= endpoint before downloading anything — it lets you filter by country, organization, or topic to find exactly what you need without browsing the full catalog.

Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

Request
const url = "https://data.humdata.org/api/3/action/package_search?q=earthquake&rows=5";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

How This API Fails

We deliberately sent this API a broken request and recorded exactly what came back on 2026-08-10. Knowing the shape of an error before you hit it makes error handling much easier to write.

HTTP 404 Requesting a path that does not exist text/html

Returned an HTML error page rather than JSON — worth knowing if your client assumes every response can be parsed as JSON.

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.

Action not found error HDX uses the CKAN API, and the endpoint path must start with /api/3/action/ followed by the exact action name.
Consult the HDX API documentation at https://data.humdata.org/api/3 for the full list of valid action names.
Empty search results Search terms may not match dataset tags or titles if the query is too specific or misspelled.
Try broader terms (e.g., 'flood' instead of 'flash flood 2023') and use the fq (filter query) parameter to narrow down results.
403 Forbidden on private datasets Some datasets on HDX are restricted and require authentication or membership approval.
Register for an HDX account and include your API key in the Authorization header for access to restricted datasets.
