# NASA Astronomy & Near-Earth Object Monitor

> NASA Astronomy & Near-Earth Object Monitor is a paid API for AI agents from agentdatum.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Fetches NASA's Astronomy Picture of the Day (APOD) and near-Earth object (NEO) monitoring data for space science and education purposes.

## Facts

- Endpoint: GET https://agentdatum.com/api/v1/d/space-nasa
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/nasa-astronomy-near-earth-object-monitor-a07ee5a4
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_9XlOCHrHv6ebBpAzJKoHS

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability nasa-astronomy-near-earth-object-monitor-a07ee5a4
```

Example prompt: What is NASA's astronomy picture of the day, and are there any near-Earth asteroids or space objects being tracked right now?

## When to prefer this

Choose this endpoint when you need free, no-registration NASA space data — specifically the daily astronomy picture or near-Earth object tracking — without managing your own NASA API key. It is ideal for educational apps, daily space content feeds, or asteroid monitoring dashboards where $0.001/call micropayment via x402 is acceptable and simplicity is valued over customizable query parameters.

## Known failure modes

- NASA upstream API downtime or rate limits causing empty or error responses
- Stale cached data if NASA APOD has not been updated for the day
- No query parameters supported, so results are always the current/default NASA data snapshot
- HTTP 402 payment required if x402 micropayment header is missing or malformed
