Options for parse_type ‘discover’, where Browser Run discovers URLs through link following and sitemaps. Ignored for ‘sitemap’.
parse_options: optional object { content_selector, include_headers, include_images, 2 more }
content_selector: optional array of object { path, selector } List of path-to-selector mappings for extracting specific content from crawled pages. Each entry pairs a URL glob pattern with a CSS selector. The first matching path wins. The crawler stores and indexes only the matched HTML fragment. Omit the field to disable content selection; the API rejects empty arrays.

Up to 5 custom HTTP headers sent with each crawl request. Names must use RFC-7230 token characters, excluding spaces, colons, and control characters. Values must use HTAB and printable ASCII only, excluding CR and LF.
sync_interval: optional 900 or 1800 or 3600 or 5 moreInterval between automatic syncs, in seconds. Allowed values: 900 (15min), 1800 (30min), 3600 (1h), 7200 (2h), 14400 (4h), 21600 (6h), 43200 (12h), 86400 (24h). Defaults to 21600 (6h); instances crawling a domain outside the account may be set to 86400.

InstanceStatsResponse object { completed, degraded, engine, 8 more }
True when the API cannot compute status counts (e.g. the legacy stats query exceeded the D1 statement-size limit). The response omits counts in this case.

chunks: array of object { id, score, text, 6 more }
Audio/video transcript chunks only: end, in milliseconds from the start of the media (whole seconds), of the last transcript section the matched chunk covers. Describes the matched chunk before any context expansion, not the expanded text.
