access_crawlAccessibility findings for every same-origin page in a site's sitemap (max 50 pages) in one combined stored report, priced from the sitemap before payment (x402): $0.05 per page for the first 25 pages, $0.02 per page beyond (price RULED). Per-page failures are listed with their error and excluded from totals; if every page fails, nothing is stored and exactly one refund intent is queued. Findings

Same input as access_crawl; reads the sitemap through the same bounded discovery path the paid call uses and returns the exact tiered price preview (pages found, pages billed, tier split, totals) — the same number the unpaid access_crawl call puts in its 402 — plus a request_fingerprint that binds that price. No page is rendered and nothing is charged. — no payment
