The provider pricing page that our daily tracker reads for this model.
Surface (checked 2026-10-08): page_url returns HTTP 500 (a 1542-byte Facebook error page, as in the hint local_probe) to the tracker's browser User-Agent, also with the .md suffix. With a non-browser User-Agent the same host returns HTTP 200, but it serves an older CMS copy (front matter 'cms: alias: /model-api/docs/pricing-rate-limits', no SAM 3.1 section). https://ai.developer.meta.com/ redirects (302) to https://dev.meta.ai/, Meta's current developer site. The fetch_url is its official Markdown twin (text/markdown, about 9 KB), linked from https://dev.meta.ai/llms.txt ('Meta Model API documentation'). The rendered page https://dev.meta.ai/docs/pricing-rate-limits (HTML, about 220 KB) shows the same Standard tier table. Muse Spark 1.3, 1.2 and 1.1 share one 'Standard tier' table (Usage | Price per 1M tokens: Cached input, Input, Output). Each model has one recipe per field. The section requires the model id (in backticks) on the 'Models:' line directly under the 'Standard tier' heading (an optional {#anchor} suffix is allowed). section_end stops at the next heading or 'Models:' line, so no recipe can read the Contributor table. Each pattern starts at a two-column table header 'Price per 1M tokens' (unit guard), steps only through table rows, and reads the exact label cell with a single price cell, so row order and added rows do not matter. The Contributor tier (muse-spark-1.3-contributor, muse-spark-1.2-contributor: training-eligible, 100 RPM) is intentionally not tracked, per MPW price_note. Web search grounding ($2.50 per 1,000 queries) is billed separately and is not part of the token rate.
