NASA offers a suite of APIs providing access to a wide range of data, including Earth science, planetary imagery, and technology transfer information.
Tools
Get Cmr Collections
Tool to retrieve collections from the Common Metadata Repository (CMR). Use when you need to search NASA science data collections by spatial, temporal, or metadata filters. Call after confirming search criteria.
Get Cmr Granules
Search for data granules in NASA's Common Metadata Repository (CMR). Granules are individual data files within a collection. REQUIRED: Specify at least one collection identifier (concept_id, provider, short_name, or version). OPTIONAL: Add spatial (bounding_box), temporal, or pagination filters to refine results. Returns metadata including download links, temporal coverage, spatial extent, and file size for each granule.
Get Eonet Categories
Tool to retrieve a list of all event categories from EONET. Use when you need current category IDs, titles, descriptions, and info links.
Get Eonet Events (atom)
Tool to retrieve a list of natural events in ATOM format. Use when you need a machine-readable XML feed of recent natural events from EONET.
Get Eonet Events Rss
Retrieve natural events from NASA's Earth Observatory Natural Event Tracker (EONET) in RSS/GeoRSS XML format. This tool provides a standardized RSS 2.0 feed with GeoRSS extensions, ideal for RSS readers, mapping applications, or systems that need spatial event data in XML format. The feed includes wildfires, storms, floods, volcanoes, icebergs, and other natural phenomena with geographical coordinates, magnitudes, and source references. Use this when you need RSS/XML format specifically. For programmatic access with structured data, consider using the JSON events endpoint instead.
Get Eonet Layers
Retrieves NASA EONET imagery layers for visualizing natural events. Returns web map service (WMS/WMTS) layer definitions that can be used to display satellite imagery related to events like wildfires, volcanoes, severe storms, etc. Each layer includes service URLs and parameters needed to fetch imagery tiles. Use the optional category parameter to get layers specific to an event type (recommended to avoid empty results).
