Format only, never validity - no VIES call, and the response says so. Reports every published pattern with its match status, enforces note 4 for ES, honours case sensitivity, and names the source's own contradictions: BE prints two patterns while note 2 denies one, RO prints nine digits while its description allows two to ten.","status":"live","indexable":true,"listed_since":"2026-10-25T17:51:04.369098Z","sources":[{"source":"x402_bazaar","external_id":"https://api.ozdreamtools.de/api/vat/format","owner_address":"0x4dd5e59475a55f1c2c0816469600663cb74cc1dc","seen_at":"2026-10-26T05:59:27.692861Z","removed_at":null}],"endpoints":[{"url":"https://api.ozdreamtools.de/api/vat/format","host":"api.ozdreamtools.de","protocol":"x402","state":"live","last_probe_at":"2026-10-25T20:31:43.184051Z","last_ok_at":"2026-10-25T20:31:43.184051Z","tools_count":null,"tools_changed_at":null,"uptime_24h":1.0,"uptime_30d":1.0}],"also_listed_as":[{"slug":"api-ozdreamtools-de-20aa3b61","name":"api.ozdreamtools.de"}],"payment_options":[],"usage":{"source":"x402_bazaar","unique_payers_30d":1,"paid_calls_30d":1,"last_paid_at":"2026-10-15T07:53:55.405Z","reported_at":"2026-10-26T05:59:27.692861Z"},"notice":"Not affiliated with addrbook — claim or request removal."}
