Indices — TTPI · TKX-GI

TKX publishes reproducible price benchmarks distilled from the same measured offers that power the boards. Methodology is versioned (M-2026.1) and public at /methodology/.

TTPI — TKX Token Price Index

The median completion-token price across all ranked offers, in USD per 1M tokens. It is reproducible: published values carry the constituent set so a third party can recompute any historical figure.

TKX-GI — GPU spot indices

Two legs: an international leg (live USD prices from Vast's public market) and a domestic leg (curated CNY snapshot). Prices are per GPU-hour.

History

Daily history windows are available for both legs — see History endpoints (/api/v1/history/ttpi.json and /api/v1/history/gpu.json).
