{"slug":"base-payee-safety-780adafe","name":"Base Payee Safety","summary":"Check a Base address before an agent pays or approves it. Input: one address. Output: allow or warn. Reports wallet or contract, whether the wallet has sent a transaction, whether a contract already had code 7 days ago, and whether it is a proxy (EIP-1967, EIP-1167, or implementation()). Warns on contract_is_new, proxy, or no_outgoing_transactions. Wallet age is unknown. A deleted contract looks like a wallet. Not proof of theft.","status":"live","indexable":true,"listed_since":"2026-10-25T17:52:18.674275Z","sources":[{"source":"x402_bazaar","external_id":"https://base-token-check.fly.dev/v1/counterparty-check","owner_address":"0x540c2aa2526c9c8c2fb4632f0fed668c36424cd5","seen_at":"2026-10-26T22:04:02.558337Z","removed_at":null}],"endpoints":[{"url":"https://base-token-check.fly.dev/v1/counterparty-check","host":"base-token-check.fly.dev","protocol":"x402","state":"live","last_probe_at":"2026-10-26T04:59:14.978315Z","last_ok_at":"2026-10-26T04:59:14.978315Z","tools_count":null,"tools_changed_at":null,"uptime_24h":1.0,"uptime_30d":1.0}],"also_listed_as":[{"slug":"base-token-check-fly-dev-bef96e08","name":"base-token-check.fly.dev"}],"payment_options":[],"usage":{"source":"x402_bazaar","unique_payers_30d":2,"paid_calls_30d":3,"last_paid_at":"2026-10-10T18:02:10.043Z","reported_at":"2026-10-26T22:04:02.558337Z"},"assessment":{"method":"2026.10.1","checks":[{"id":"answers","state":"pass","reason":"Answered a check 9 hours ago."},{"id":"owner","state":"fail","reason":"No one has proven control of its domain or of the wallet it is paid at."},{"id":"track_record","state":"fail","reason":"Listed for 0 days; 30 are needed."},{"id":"real_customers","state":"fail","reason":"2 different wallets paid it in 30 days, as the x402 Bazaar reports (not yet counted by addrbook); 10 are needed."},{"id":"clean_scan","state":"not_applicable","reason":"Not an MCP server."}],"passed":1,"applicable":4,"contradicted":false,"computed_at":"2026-10-26T14:49:59.163755Z"},"identity":{"endpoint_domains":["base-token-check.fly.dev"],"proven_domains":[],"proven_wallets":[],"namesakes":[],"namesake_count":0,"identity_checks":[],"wallet_attestations":[]},"replies":[],"customers":null,"scan":null,"notice":"Not affiliated with addrbook — claim or request removal."}
