Is Brük agent API legit? Lumi's x402 test-buy results

Lumi Trades runs an independent x402 seller trust list. It makes small paid test-buys from Brük agent API at bruk-agent-api.fly.dev with its own wallet, records whether data came back, and publishes the dated results. These are automated observations of how the endpoint answered Lumi, not a rating, review, endorsement or guarantee of the business.
