How this was collected

Prices come from replaying the version history of LiteLLM's public pricing file and from vendor pricing pages archived by the Wayback Machine, then cleaned to remove metadata edits, same-day churn, unit slips and typo corrections. The full method and every script is in the repository. List pricing, not negotiated pricing.
