{"slug":"2s-4c8fbdf1","name":"2s","summary":"Grade a domain's email-authentication and DNS-security posture from live DNS in one call: SPF, DMARC (policy + alignment), DKIM (for the supplied or common selectors), MTA-STS, TLS-RPT, DNSSEC, CAA, and BIMI. Pass domain (and optional dkimSelector). Returns an overall letter grade, a summary (spf/dmarcPolicy/dkim/mtaSts/dnssec/caa/bimi + spoofingProtected), and a per-mechanism block with the raw record, parsed tags, and specific issues (e.g. 'DMARC p=none — monitor only', 'SPF ~all soft-fail', 'no MTA-STS'). Sourced from live public DNS via DNS-over-HTTPS — an LLM cannot know a domain's current records. For deliverability/anti-spoofing audits, vendor security review, and phishing-resistance checks. DKIM is selector-based (selectors aren't enumerable), so 'not found' only means none of the checked selectors resolved.","status":"live","indexable":true,"listed_since":"2026-10-25T17:53:37.864367Z","sources":[{"source":"x402_bazaar","external_id":"https://2s.io/api/domain/email-security","owner_address":"0x2b6d4988db4723e6908db86ab2b8dfbc51fc32c5","seen_at":"2026-10-27T12:31:30.288610Z","removed_at":null}],"endpoints":[{"url":"https://2s.io/api/domain/email-security","host":"2s.io","protocol":"x402","state":"live","last_probe_at":"2026-10-26T09:35:57.670953Z","last_ok_at":"2026-10-26T09:35:57.670953Z","tools_count":null,"tools_changed_at":null,"uptime_24h":null,"uptime_30d":1.0}],"also_listed_as":[{"slug":"2s-io-49c1cd49","name":"2s.io"}],"payment_options":[{"endpoint_url":"https://2s.io/api/domain/email-security","network":"eip155:8453","scheme":"exact","rail":"exact","asset":"0x833589fcd6edb6e08f4c7c32d4f71b54bda02913","coin":"USDC","asset_label":"USD Coin","amount":"4500","pay_to":"0x2b6d4988db4723e6908db86ab2b8dfbc51fc32c5","observed_at":"2026-10-26T09:35:57.670953Z"},{"endpoint_url":"https://2s.io/api/domain/email-security","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","scheme":"exact","rail":"exact","asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","coin":"USDC","asset_label":"USDC","amount":"4500","pay_to":"TW6ntaGzvj63ZgPjszd4FCGmVTGfzv1MAYZbjYcyWhn","observed_at":"2026-10-26T09:35:57.670953Z"}],"usage":{"source":"x402_bazaar","unique_payers_30d":3,"paid_calls_30d":3,"last_paid_at":"2026-10-20T21:22:18.467Z","reported_at":"2026-10-27T12:31:30.288610Z"},"assessment":{"method":"2026.10.2","checks":[{"id":"answers","state":"pass","reason":"Answered a check 20 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":"2026-10-27T06:00:58.645407Z"},"identity":{"endpoint_domains":["2s.io"],"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."}
