The provider pricing page that our daily tracker reads for this model.
fetch_url is the official .md twin of page_url (same document, also fetched by platform-claude-com-docs-en-about-claude-pricing-md). page_url itself returns markdown only when the Accept header lists text/markdown (the server sends Vary: Accept; an HTML-only Accept gets the 936 KB HTML page), so the .md twin, which returns markdown for any Accept, is fetched with an explicit accept header. Recipes read only the "## Model pricing" table: section anchors on its header row "| Model | Base input tokens | 5m cache writes | 1h cache writes | Cache hits and refreshes | Output tokens |" (the two cache-write names are wildcards), which proves the column order the patterns rely on; section_end ^(?!\|) stops at the first line that is not a table row. Each pattern ends the model name with " |" (Opus 5 cannot match Opus 5.5, Fable 5 cannot match Fable 5.1, Sonnet 5 cannot match Sonnet 5.5) and requires exactly six cells, so an added, removed or reordered column fails loudly instead of shifting fields. Page rows that MPW does not cite for this page are not tracked: Mythos 5.1, Mythos 5, Opus 4.1, Opus 4, Sonnet 4, Haiku 5.5 (two prompt-length tiers) and Haiku 3.5. Fable 5.1 is tracked by the -md source.
