}价格数据缓存
getAsset返回的价格数据是缓存的，可能不是最新的。价格信息有600秒的缓存，这意味着数据可能有最多600秒的延迟。
token_info.price_info部分找到。对于需要实时定价的应用程序，请考虑实施额外的验证。
MPL Core 代理和 MIP-11 组
当存在时，响应可以包括is_agent、agent_token、asset_signer、interface 等值，例如 MplCoreGroup，以及一个用于 MIP-11 成员资格的 plugins.groups 对象。相同的可选字段由 getAssetBatch、getAssetsByOwner、getAssetsByGroup、getAssetsByCreator、getAssetsByAuthority 和 searchAssets 返回。请参阅 资产搜索指南 以获取 searchAssets 过滤器。
