Robinhood Chain (id 4663) early-token risk radar. Ranked risk score 0-100 (higher = riskier).

Also: deployer class, fresh-pool age, sell pressure, volume-vs-depth, microcap. Intelligence only.

Claim Verifier (adversarial)$0.005
Adversarial claim verification. POST {claim, checks:[...]} — each check is an independent probe against the primary source (HTTP/x402 challenge/DNS/EVM tx/call/balance/hash). Returns per-check PASS / FAIL / UNVERIFIABLE with raw evidence and a reproduce command, plus an overall verdict (CONFIRMED / REFUTED / PARTIALLY_VERIFIED). Claims are never scored on plausibility: FAIL means the primary source contradicts the claim, UNVERIFIABLE means the claim cannot be probed and is therefore not evidence. Use it to audit another agent's stated numbers, payment addresses, treasury balances, contract ownership, or x402 pricing before you pay them. Check type x402_enforce goes further: it asks whether a seller's paywall actually holds, by re-requesting with no payment header, a forged tx hash, and a malformed header — a 2xx with a body on any of those means the seller charges for data that free-riders already get, so your payment buys nothing. It also reports the size of the x402 v2 challenge header: past 16KB, undici (every Node/JS agent) fails with UND_ERR_HEADERS_OVERFLOW and cannot buy at all, while a curl-based check still reports the endpoint healthy.
