## 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 orrery-astrology-api-23445821 -d '<json body>'
```

Example prompt: Pull up the full astrological natal chart stack for someone born on June 14, 1988 at 3:22am in Chicago, Illinois — use the standard four-way spread.

## When to prefer this

Choose this endpoint when you need programmatic, machine-readable astrological natal chart computation — especially when you need planetary positions, house placements, and angular data for a specific birth moment and location. Ideal for astrology apps, personality profiling tools, or AI agents that incorporate astrological context. Supports unknown birth times and multiple astrological framework presets.

## Known failure modes

- Invalid or unparseable date-time string returns a validation error
- Unrecognizable place name fails geocoding and returns an error
- Unknown framework preset ID returns an error
- Missing required 'when' or 'where' fields returns a 400-level error
- Payment not included or insufficient results in 402 Payment Required

## How this service works

Astrology for robots.

## Output

Returns a structured astrological 'stack' object containing planetary positions, house cusps, angular points, and framework-specific spread data computed for the given birth moment and location. When time_unknown is set, house and angle data are flagged as unreliable. The response is a flexible object with additional properties reflecting the chosen framework.
