## How to call it through Zero

```sh
zero fetch --capability multi-framework-birth-chart-api-a2c3a228
```

Example prompt: Can you pull a full multi-system birth chart for someone born on March 14, 1988 at 7:30 AM in Chicago, USA — I want western astrology, Vedic, BaZi, numerology, I-Ching bodygraph, and biorhythms all in one shot, and their full name is James Alan Cooper?

## When to prefer this

Use this endpoint when you need all major esoteric personality systems (western astrology, Vedic, BaZi, numerology, I-Ching bodygraph, biorhythms) in a single deterministic call rather than calling separate specialized endpoints. Prefer this over the western-only natal astrology sibling endpoint when multi-framework output is needed. Ideal for holistic personality profiling apps, astrology platforms, or AI agents that need comprehensive birth-chart data without chaining multiple API calls.

## Known failure modes

- Missing required 'date' parameter returns a validation error
- Invalid date format (not YYYY-MM-DD) causes a parsing error
- Unrecognized 'place' string fails geocoding and returns an error
- Passing both 'tz' and 'utc_offset' may cause ambiguity or conflict
- No 'time' provided results in a no-time chart with houses, Ascendant, and exact Moon degree flagged as unavailable
- Invalid lat/lon values outside valid ranges cause a coordinate error

## How this service works

Multi-framework birth-chart in ONE call: western natal astrology, Vedic sidereal positions, Chinese BaZi, Pythagorean numerology, a neutral I-Ching bodygraph and biorhythms. Give a birth date (optional time, place or lat and lon, and tz or utc_offset) and get cited JSON across every system. Deterministic, no LLM, no keys.

## Output

A cited JSON object containing: tropical planet placements by sign and degree with retrograde flags, Vedic sidereal positions, Chinese BaZi four pillars, Pythagorean numerology life path and name numbers, I-Ching gate and line activations for personality and design, and biorhythm cycle percentages — all derived deterministically with no LLM.
