# Human Design bodygraph (public, no key)

`POST https://api.astroway.info/v1/public/human-design`

Type, strategy, authority, profile, defined centres, channels and gates. Same input and same engine as the authed POST /human-design, served anonymously under the public rate limit. Responses carry the free-tier `_footer` watermark. Centre identifiers are PascalCase with no separator and are stable: `Head`, `Ajna`, `Throat`, `G`, `Heart`, `SolarPlexus`, `Spleen`, `Sacral`, `Root`; `channels[].centerA` and `centerB` use the same nine. `localized` carries type, strategy, authority and the centre names in the requested language, keyed by the same identifiers, so a caller reads `localized.centers.SolarPlexus` and never matches on a translated string. The English values above it are the stable ones and never change. Channel and gate names are prose rather than a closed set and stay English.

Group: Public. Auth: none, this endpoint answers without a key.

## Parameters

| Name | In | Required | Type | Description |
|---|---|---|---|---|
| `Accept-Language` | header | no | string | BCP-47 language (e.g. `uk`, `en`, `de`). Set it once on your HTTP client as its default; for a single call, `?lang=` overrides it. Unknown or inactive codes fall back to `uk`. |
| `lang` | query | no | string | Language for this call, overriding `Accept-Language`. The canonical per-call form: a page that renders in one language passes it here rather than reconfiguring its client. Unknown or inactive codes fall back to `uk`. |
| `fields` | query | no | string | Comma-separated dotted paths, relative to `data`, to keep in the response. A path is applied to every element of an array, so `planets.name` means the name of each planet. Paths that match nothing come back in `_fields_unmatched`; a list where nothing matches at all is a 400, because an empty object would be a confident wrong answer. |
| `precision` | query | no | integer | Round every non-integer number in the response to this many decimal places. Integers are left alone, because an id is not a measurement. Ecliptic longitudes ship with fourteen decimals by default; 2 is about a tenth of an arcminute. |

## Request body

| Field | Type | Required | Description |
|---|---|---|---|
| `date` | string | yes |  |
| `time` | string | yes |  |
| `timezoneOffset` | number | no | Hours from UTC at the given moment, not minutes. Fractional zones are hours too: 5.5 for India, 5.75 for Nepal, -3.5 for Newfoundland. Defaults to 0, meaning UTC. Ignored when timezone is sent. |
| `timezone` | string | no | IANA zone name such as Europe/Kyiv, or auto to look the zone up from latitude and longitude. The server takes the offset that zone kept at this local date and time, summer time included, and uses it in place of timezoneOffset. A clock time that happened twice takes the first occurrence; one skipped when clocks went forward takes the offset from before the change. Abbreviations such as EST are refused. Before 1970 the tz database is not reliable for every place, so send timezoneOffset when the local clock is known. |
| `latitude` | number | yes |  |
| `longitude` | number | yes |  |
| `houseSystem` | "P" \| "K" \| "R" \| "C" \| "E" \| "W" \| "B" \| "M" \| … | no |  |
| `name` | string | no |  |
| `city` | string | no |  |
| `zodiacType` | "tropical" \| "sidereal" | no |  |
| `ayanamsaId` | number | no |  |
| `ayanamsa` | "fagan-bradley" \| "lahiri" \| "de-luce" \| "raman" \| "krishnamurti" \| "kp" \| "yukteshwar" \| "jn-bhasin" \| … | no | Sidereal school by name. Lahiri when omitted. Equivalent to ayanamsaId; send either. |
| `cosmogram` | boolean | no |  |
