TAP Certified referee fee for one job with a budget up to $25.00: the seller's code is judged on the buyer's hidden tests in a sealed sandbox, and the escrow pays out or refunds on the verdict.
What this grade does and doesn't measure: it scores the paid-request handshake — whether the service returns a spec-valid 402 payment challenge, how fast, and whether its price is honest. We do not pay these endpoints yet, so we do not verify that the paid response returns correct or complete content. Availability is a probe success rate measured hourly, corroborated by a second network path for this service.
