Changelog
kstartup/announcements and kstartup/business-info are hard-breaking contract standardizations. The provider still sends K-Startup's required returnType=json, page, and perPage parameters internally, but callers now use APIFuse semantic field names.
For announcements, replace perPage with limit, biz_pbanc_nm with query, supt_regin with support_region, supt_biz_clsfc with support_field, pbanc_rcpt_bgng_dt with application_start_date in YYYY-MM-DD format, pbanc_rcpt_end_dt with application_end_date in YYYY-MM-DD format, aply_trgt with target_audience, biz_enyy with startup_age, biz_trgt_age with target_age, rcrt_prgs_yn Y/N with recruitment_status open/closed, and intg_pbanc_yn Y/N with integrated_announcement true/false. For business-info, replace perPage with limit, biz_yr with year, biz_category_cd with category_code, and supt_biz_titl_nm with query. Read results from items and summary instead of data and query.
