Signature Analysis

Endpoint POST https://starsapi.com/api/v3/numerology/analyze/signature

Analyzes the numerological vibration of a signature (name as signed). Compares it against birth numbers for alignment. Supports three letter-value systems — Chaldean (default), Pythagorean, and Indian — via the optional system parameter.

Authentication

Required. Three methods accepted:

Method	Example
Header (recommended)	`X-Api-Key: am_live_xxxxxxxxxxxx`
Bearer	`Authorization: Bearer am_live_xxxxxxxxxxxx`
Body	`"api_key": "am_live_xxxxxxxxxxxx"`

Request body

Send a JSON object with Content-Type: application/json.

Field	Type	Required	Description
`name`	string	Yes	Full name (first + last). Used for letter-value calculations.
`year`	integer	No	Birth year (enables personalization).
`month`	integer	No	Birth month, `1`–`12`.
`day`	integer	No	Day of month, `1`–`31`.
`system`	string	No	Letter-value system: `pythagorean`, `chaldean`, or `indian`. Default `chaldean`.

Response

Returns a v3 envelope with data containing the numerology results and meta with request metadata. See the code pane for a sample response.
