# Bu0y
> Best-execution inference router. One OpenAI-compatible endpoint quotes every marketplace and fills at the cheapest source that can actually deliver. Site https://bu0y.com. API https://api.bu0y.com.

Money is prepaid non-refundable credits in integer microdollars ($1 = 1_000_000). Routing is source-blind. Bu0y does not store prompts or completions; billing metadata only; the fill marketplace still receives the prompt. Agents mint `bu0y_…` keys with a Solana wallet signature. Humans use passkeys on the account desk, then mint keys there.
