Look up multiple IDs in one request

Deprecated. Prefer POST /batch/resolve for all bulk lookups — it is provider-aware, supports the targets parameter for response narrowing, and echoes each input back in the from field for easy correlation.

Batch lookup by Reep IDs or Wikidata QIDs. Accepts a mix of both. A single QID may return multiple records if the person is both a player and coach. Results are flattened into a single array, so the response count may exceed the number of ids in the request. Maximum 100 IDs per request.
