NASA Open APIs (APOD + Mars rover)
NASA's Open APIs expose various Mars rover and astronomy datasets for public use — including the famously-popular Astronomy Picture of the Day. Tiny Command exposes two actions, no triggers: Astronomy Picture of the Day (returns the day's NASA-curated image with title, explanation, and image URL — popular for daily Slack bots and "image of the day" workflows in news/education contexts), Mars Rover Photos (paginated photos from the Curiosity, Opportunity, and Spirit rovers — filterable by Earth date and camera). The connection uses a NASA API key from api.nasa.gov (free, registration takes one minute). For workflows that want to display daily fresh NASA content (educational Slack channels, science newsletters, ambient displays), this is the source. APOD is the most widely-used NASA endpoint; Mars Rover photos are useful for "show me a fresh Mars image" workflows.

Every action accepts dynamic inputs from upstream nodes, whether that's an AI output, a form field, or a search result.
| Action | What it does | Open action |
|---|---|---|
| Get NASA APOD | Returns the day's astronomy image with title, explanation, image URL. For "daily NASA image in Slack" or "weekly science newsletter image" workflows. | |
| Get NASA Mars Rover Photos | Returns photos from Curiosity/Opportunity/Spirit rovers for a specific Earth date. For "today on Mars" workflows (query yesterday's Earth date for lag in Mars-to-Earth transmission). |

Tiny Command counts a run the moment a trigger fires. Filtering early means only matching events spend your usage budget.
Connect NASA once and every workflow on your account can use its triggers and actions. You don't have to re-auth per workflow.
Every NASA field shows up in the visual picker for downstream nodes. The raw payload is there for power users, optional for everyone else.
