{"slug":"email-verification-smtp-2f0fd7fb","name":"Email Verification SMTP","summary":"Email verification: checks whether an email address really exists by asking its mail server (SMTP RCPT TO probe; no email is sent), on top of syntax, MX, disposable and role checks. Returns status deliverable, undeliverable (mailbox does not exist), catch_all (domain accepts any address), risky (disposable or mailbox full) or unknown (greylisting, server refused the check), plus the raw SMTP reply. Use it before sending outreach, to clean lead lists or to block fake sign-ups.","status":"live","indexable":true,"listed_since":"2026-10-25T17:51:19.775164Z","sources":[{"source":"x402_bazaar","external_id":"https://agentsvc.io/api/v1/proxy/email-verify","owner_address":"0x622efa6ceb83a5b6edbc931332f4db68b7f74f27","seen_at":"2026-10-27T05:50:48.261689Z","removed_at":null}],"endpoints":[{"url":"https://agentsvc.io/api/v1/proxy/email-verify","host":"agentsvc.io","protocol":"x402","state":"live","last_probe_at":"2026-10-26T12:44:50.732371Z","last_ok_at":"2026-10-26T12:44:50.732371Z","tools_count":null,"tools_changed_at":null,"uptime_24h":1.0,"uptime_30d":1.0}],"also_listed_as":[{"slug":"agentsvc-io-ffdf840f","name":"agentsvc.io"}],"payment_options":[{"endpoint_url":"https://agentsvc.io/api/v1/proxy/email-verify","network":"eip155:8453","scheme":"exact","rail":"exact","asset":"0x833589fcd6edb6e08f4c7c32d4f71b54bda02913","coin":"USDC","asset_label":"USD Coin","amount":"2500","pay_to":"0x622efa6ceb83a5b6edbc931332f4db68b7f74f27","observed_at":"2026-10-26T12:44:50.732371Z"},{"endpoint_url":"https://agentsvc.io/api/v1/proxy/email-verify","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","scheme":"exact","rail":"exact","asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","coin":"USDC","asset_label":null,"amount":"2500","pay_to":"5JzPS5qpEwUM1vTC9GG7uqvwJdHzbEwfoPHf2Ki977tg","observed_at":"2026-10-26T12:44:50.732371Z"}],"usage":{"source":"x402_bazaar","unique_payers_30d":3,"paid_calls_30d":15,"last_paid_at":"2026-10-26T04:06:46.504Z","reported_at":"2026-10-27T05:50:48.261689Z"},"assessment":{"method":"2026.10.2","checks":[{"id":"answers","state":"pass","reason":"Answered a check 17 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 1 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":"2026-10-27T05:50:48.610082Z"},"identity":{"endpoint_domains":["agentsvc.io"],"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."}
