{"slug":"agents-factstamp-dev-vat-4c8d00c3","name":"agents.factstamp.dev/vat","summary":"An EU VAT number check — VAT validity, and the VAT registration behind it. Relevant wherever a VAT number is being relied on or cited: the check reads the official VIES service (European Commission), keyless, and returns valid, invalid or unknown — an outage is never reported as invalid — with the member state, the register's own request date, and the trader identity only where that member state discloses it. GB is out of scope after Brexit; XI (Northern Ireland) is covered. Not tax advice.","status":"live","indexable":true,"listed_since":"2026-10-25T17:52:52.490895Z","sources":[{"source":"x402_bazaar","external_id":"https://agents.factstamp.dev/vat","owner_address":"0xc3bcd24a2b350cc73b8516b2a0539a323b42cc32","seen_at":"2026-10-27T21:42:27.916077Z","removed_at":null}],"endpoints":[{"url":"https://agents.factstamp.dev/vat","host":"agents.factstamp.dev","protocol":"x402","state":"live","last_probe_at":"2026-10-28T02:32:14.132079Z","last_ok_at":"2026-10-28T02:32:14.132079Z","tools_count":null,"tools_changed_at":null,"uptime_24h":1.0,"uptime_30d":1.0}],"also_listed_as":[{"slug":"agents-factstamp-dev-e811d8a9","name":"agents.factstamp.dev"}],"payment_options":[{"endpoint_url":"https://agents.factstamp.dev/vat","network":"eip155:8453","scheme":"exact","rail":"exact","asset":"0x833589fcd6edb6e08f4c7c32d4f71b54bda02913","coin":"USDC","asset_label":"USD Coin","amount":"50000","pay_to":"0xc3bcd24a2b350cc73b8516b2a0539a323b42cc32","observed_at":"2026-10-28T02:32:14.132079Z"}],"usage":{"source":"x402_bazaar","unique_payers_30d":3,"paid_calls_30d":3,"last_paid_at":"2026-10-25T16:53:03.459Z","reported_at":"2026-10-27T21:42:27.916077Z"},"assessment":{"method":"2026.10.2","checks":[{"id":"answers","state":"pass","reason":"Answered a check 3 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 2 days; 30 are needed."},{"id":"real_customers","state":"fail","reason":"3 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":"2026-10-28T06:02:40.696808Z"},"identity":{"endpoint_domains":["factstamp.dev"],"proven_domains":[],"proven_wallets":[],"namesakes":[],"namesake_count":0,"identity_checks":[],"wallet_attestations":[],"human_backings":[]},"replies":[],"customers":null,"scan":null,"notice":"Not affiliated with addrbook — claim or request removal."}
