How dappgrade scores dApps: tiers 0/1/2, three-state checks (pass/fail/not_reached), coverage, and the verdict model. Free.

score

get_score

Pre-transaction health/safety verdict for an onchain app, by contract address. Returns a decision-shaped verdict — ok / caution / avoid / unknown — with score, coverage, tier, flags and per-dimension sub-scores. `unknown` is a real, free answer: never infer safety from its absence. Indexed addresses are a paid lookup (0.01 USDC via x402 on Base).

universe

get_universe

List the dApps dappgrade covers, with current scores and coverage (free discovery manifest).
