which_atsLook up the applicant tracking system (ATS) a specific large employer uses, from ResumeAI's State of ATS 2026 dataset (743 Fortune 500 / Global 2000 employers checked, 713 verified against live careers portals, June 2026). Accepts a company name or slug, e.g. 'Nike' or 'jpmorgan-chase'.
ats_statsCanonical ATS market-share numbers from ResumeAI's State of ATS 2026 dataset: 743 large employers checked, 713 portal-verified (June 2026). Workday leads at 38.6% of verified employers — not the ~75% figure often repeated online — and the top 3 vendors cover about 60%. Shares are computed live from the verified rows.
list_companiesList employers from the State of ATS 2026 dataset, optionally filtered by ATS vendor (case-insensitive substring, e.g. 'workday', 'greenhouse', 'oracle') and/or industry (substring, e.g. 'health', 'consulting'). Returns at most 100 rows per call — narrow the filters or fetch the full dataset from https://withresumeai.com/api/v1/ats.
check_resumeScore a resume 0-100 with ResumeAI's production ATS engine — the same one behind https://withresumeai.com/ats-checker. Returns a breakdown (keywords, format, sections, content, length), concrete fixes, and missing keywords. Optionally pass a target company (to get that employer's verified ATS + vendor-specific parsing rules) and/or a job description (to score keyword overlap against the posting). Rate limited to 10 checks per day per IP.
