Nasa

NASA data API for near-Earth objects, planetary imagery, satellite orbits, technical reports, atmospheric data, and CMR metadata.

Helps space and earth-science apps that browse asteroids, request orbital graphs, download NTRS citations, and read AGAGE atmospheric data.

Example Use Cases

These are the Nasa actions Snow can use when building apps with you. Connecting an account does not make Snow run these on its own.

Browse Near Earth Objects

Browse the complete NASA near-Earth object (asteroid) dataset with pagination support. Returns comprehensive asteroid data including orbital parameters, estimated diameters, close approach events, and hazard classifications. Use this when you need to explore the entire NEO catalog or retrieve multiple asteroids across pages.

Get Astronomy Picture of the Day

Retrieves NASA's Astronomy Picture of the Day (APOD) for a specified date or today. Returns image/video URL, title, explanation, and metadata including copyright and high-resolution URLs when available. Use this when you need to access NASA's daily astronomy images or their descriptions. Valid for dates from June 16, 1995 to present.

Get Citation by ID

Tool to retrieve detailed citation information from NASA Technical Reports Server (NTRS) by citation ID. Use when you need complete metadata for a specific NASA scientific or technical document, including abstract, authors, publication details, copyright information, export control status, and download links.

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. Omitting or broadening spatial/temporal filters can return extremely large datasets; always constrain both when possible. Returns metadata including download links, temporal coverage, spatial extent, and file size for each granule.

Get DONKI CME Data

Tool to retrieve Coronal Mass Ejection (CME) data from NASA's DONKI database. Use when you need detailed information about solar CME events including their speed, direction, source location, instrument detections, and impact predictions. Returns comprehensive CME analysis with ENLIL model simulations for space weather forecasting.

Get DONKI Solar Flares

Tool to retrieve Solar Flare (FLR) events from NASA's DONKI (Space Weather Database Of Notifications, Knowledge, Information). Use when you need data about solar flares including their classification (B, C, M, X-class), timing (begin/peak/end), source location, and associated instruments. Returns events within the specified date range, defaulting to the last 30 days if no dates provided.

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. Note: category IDs are EONET-specific and do not map to CMR (Common Metadata Repository) IDs; use them only for EONET-internal filtering, not cross-system lookups.

Get EONET Events

Tool to retrieve natural events from NASA's Earth Observatory Natural Event Tracker (EONET). Use when you need structured JSON data about wildfires, storms, floods, volcanoes, earthquakes, and other natural phenomena. Supports filtering by source, category, status, date range, magnitude, and geographic bounding box.

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.
