GET https://402.com.tr/api/x402/wallet-drain-watch · 2 observations
One GO/REVIEW/STOP across every drain vector: EIP-7702 delegation (a hostile delegate is total takeover), Base Account spend permissions (unbounded, non-expiring pulls), and ERC-20 approvals (unlimited allowance to unknown spenders). Composes wallet-delegation + spend-audit + approval-advisor so an agent checks its whole surface in one call instead of three; drill into each vector for detail. A vector that could not be read is 'unknown', never clear. Not financial advice.

Wallet age in days, first & last activity timestamps, and outgoing transaction count for any Base address — read straight from the Base archive, not a 30-day feed, so it dates wallets of any age. Counts and last-activity cover what the wallet SENT; inbound transfers don't raise the nonce and aren't counted. Built for sybil screening and counterparty trust checks.

GET https://402.com.tr/api/x402/wash-trading · 2 observations
Hot volume is often fake. This reads a token's transfer events and flags the wash/circular shape: the share of transfers round-tripping through addresses active on BOTH the send and receive side, plus participant concentration. Returns clean / elevated / likely_wash with the top round-trippers. A heuristic signal, not proof — LPs and routers legitimately sit on both sides — so size off it, don't convict on it. Pass days= (default 7). Not financial advice.

Flow, not snapshot: the largest transfers of a Base token in the last 24h, classified by whether whales are sending INTO DEX pools (sell pressure) or pulling OUT (accumulation) — a net sell-pressure read that decays in hours. Complements holder-forensics ('who could dump') with 'is anyone dumping now'. CDP-indexed events.

x402 proves payment, not trust: an agent handed a URL pays blind, and the payee may be a real service or a burner that takes the USDC and vanishes. Give a url and/or a payTo wallet and get GO/WARN/STOP: is the URL a well-formed 402 resource, does its price match, and is the seller wallet sanctioned, a fresh throwaway, or paying a different address than you expected. Screens the PAYMENT side the protocol drops — not a guarantee the service returns good data.

Use it to check a site is live, detect stale data, monitor a page for changes, or decide whether to invalidate a cache before your agent acts on what it says. Returns a signed attestation.

Counts describe directory coverage, including testnets. Each resource groups the same URL, HTTP method or MCP tool across sources. A catalog sighting records published terms. A live 402 records the endpoint’s reply to an unpaid request.
