title: 'PromptSpend'
abstract: >-
  A web application and open dataset for estimating, comparing and understanding
  what large language model API usage will cost. Prices are re-checked every
  morning by an automated pipeline that reconciles two independent upstream
  sources against hand-verified vendor overrides; every price carries its source
  URL and the date it was last confirmed, and every change lands as a reviewable
  commit. Ships with a public keyless pricing API, an MCP server, and a VS Code
  extension.
