grade evidence: hourly probes of /defi/yields. Availability, latency and protocol measure the operator's shared infrastructure and generalize across its products; the price check applies to the probed product. We now also probe one other product per hour, rotating; "live price we measured" shows what each answered.

Compare DeFi pool yields across chains with built-in risk screening. Filters by chain, asset and minimum TVL, and flags trap yields — unsustainable APY, reward-token dependence, low TVL, impermanent-loss and ML-predicted decline — so agents don't chase …

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.
