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 space-x402-press-space-ask-c49533c8 -d '<json body>'
```

Example prompt: When is the next visible meteor shower from the Northern Hemisphere, and what time should I go outside to see it?

## When to prefer this

Choose this endpoint when you need natural language reasoning about any astronomy or space topic — especially when combining multiple data types (e.g. event timing + visibility + context). It is ideal for conversational agents answering user questions about space without needing a structured API per topic. Prefer it over specialized NASA or observatory APIs when the question is open-ended or spans multiple domains.

## Known failure modes

- Overly vague or ambiguous questions may yield generic answers without specific data
- Questions requiring real-time positional data for a specific observer location may lack precision
- Very recent events beyond the model's knowledge cutoff may not be accurately reflected
- Payment failure or insufficient USDC balance will block the request

## How this service works

Multi-source AI space reasoning via DeepSeek. Accepts any natural language question about celestial events, planets, moons, asteroids, comets, meteor showers, eclipses, satellites, ISS, rocket launches, space weather, stars, or deep-sky objects.

## Output

A natural language AI-generated response synthesized from multiple sources, providing detailed information about the queried space topic — including event timing, visibility conditions, scientific explanations, orbital data, mission details, or observational tips as relevant.
