Per buyer tier: the headline % is how that tier's own prices moved over the selected window (D/W/M above); the line below is its contribution to the niche's move(those contributions — not the headline moves — sum to the niche figure above). A thin tier (1–2 comparable agents) is shown and flagged, not hidden.

Methodology. Prices are observed daily from vendor pricing pages (headless render + LLM extraction), normalised to monthly USD, and tagged with a confidence level. Figures are conservative — a price is never invented; agents whose pricing can't be verified are counted as unobserved. Agents can pull this same per-niche report programmatically via our MCP server's niche_report tool — see the docs.
