oj_capabilitiesread-only | Report the audited anonymous AtCoder read surface and explicitly unsupported operations. |
oj_fetch_problemread-only | Fetch one public problem statement from an exact contest/task pair or canonical atcoder.jp task URL. Returns sanitized HTML with preserved math, samples, limits, hashes, and source provenance. |
oj_healthread-only | Report local readiness and the latest observed AtCoder page-read status without probing upstream. |
oj_search_problemsread-only | Resolve exactly one contest/task id, atcoder:contest/task id, or canonical task URL. Free-text and catalog crawling are not supported. |
