Get asset metadata

Authenticated asset lookup. GET accepts required ids and fields as comma-separated or repeated query parameters; at most 100 IDs before deduplication. Supported fields: name, symbol, decimals, price, logo. QUERY /assets is also supported (not representable as an OpenAPI 3.1 operation): send application/json {"ids":["eip155:1:native"],"fields":["symbol","price"]}, at most 100 IDs and a 64 KiB body. Both methods return exact submitted ID keys, omit unrequested fields and use null for unresolved requested fields; item errors remain HTTP 200. An invalid request returns 400 with {"error":{"code":"invalid_request","message":"..."}}.
