Crustdata API / Get autocomplete suggestions for person search fields

Return ranked field-value suggestions for any supported person search field. Use this endpoint to discover the exact indexed values that /person/search filters expect — feed the suggestion value back into a search filter verbatim to retrieve the matching profiles. Pass a partial query string for type-ahead behaviour, or pass an empty query to retrieve the most common values for the field by frequency. Suggestions always come from the whole dataset. There is no filters scope; a filters key is ignored. The top-level field must be one of the supported autocomplete fields — an allowlisted subset of the field names used by /person/search, not every field exposed in its request and response schemas. Sending an unsupported field returns a 400 whose error message lists every accepted field. Default rate-limit is 45 requests per minute. Send an email to gtm@crustdata.co to discuss higher limits if needed for your use case.
