Use when an agent needs a domain's DKIM keys but does not know the selector. Finding none is a hint, not proof that DKIM is missing.","status":"live","indexable":true,"listed_since":"2026-10-26T06:01:33.865789Z","sources":[{"source":"x402_bazaar","external_id":"https://api.probekit.dev/v1/mail/dkim-discover","owner_address":"0x5be2be9f95549a2d69951d24a2b3901d1df1bc05","seen_at":"2026-10-27T21:43:13.739969Z","removed_at":null}],"endpoints":[{"url":"https://api.probekit.dev/v1/mail/dkim-discover","host":"api.probekit.dev","protocol":"x402","state":"live","last_probe_at":"2026-10-27T19:10:07.716703Z","last_ok_at":"2026-10-27T19:10:07.716703Z","tools_count":null,"tools_changed_at":null,"uptime_24h":1.0,"uptime_30d":1.0}],"also_listed_as":[{"slug":"api-probekit-dev-0d62db6e","name":"api.probekit.dev"}],"payment_options":[{"endpoint_url":"https://api.probekit.dev/v1/mail/dkim-discover","network":"eip155:8453","scheme":"exact","rail":"exact","asset":"0x833589fcd6edb6e08f4c7c32d4f71b54bda02913","coin":"USDC","asset_label":"USD Coin","amount":"20000","pay_to":"0x5be2be9f95549a2d69951d24a2b3901d1df1bc05","observed_at":"2026-10-27T19:10:07.716703Z"}],"usage":{"source":"x402_bazaar","unique_payers_30d":1,"paid_calls_30d":1,"last_paid_at":"2026-10-25T18:46:54.161Z","reported_at":"2026-10-27T21:43:13.739969Z"},"assessment":{"method":"2026.10.2","checks":[{"id":"answers","state":"pass","reason":"Answered a check within the last hour."},{"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":"1 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":"2026-10-27T19:10:45.810752Z"},"identity":{"endpoint_domains":["probekit.dev"],"proven_domains":[],"proven_wallets":[],"namesakes":[{"slug":"probekit-37bf3ce3","name":"ProbeKit","proven_domain":null},{"slug":"probekit-39391b06","name":"ProbeKit","proven_domain":null},{"slug":"probekit-c72619e8","name":"ProbeKit","proven_domain":null},{"slug":"probekit-2c09174d","name":"ProbeKit","proven_domain":null},{"slug":"probekit-bfd1c09b","name":"ProbeKit","proven_domain":null},{"slug":"probekit-4fcd5ba6","name":"ProbeKit","proven_domain":null},{"slug":"probekit-b0c7dbdf","name":"ProbeKit","proven_domain":null},{"slug":"probekit-3b7eb36c","name":"ProbeKit","proven_domain":null},{"slug":"probekit-8ab7174d","name":"ProbeKit","proven_domain":null},{"slug":"probekit-4a894523","name":"ProbeKit","proven_domain":null}],"namesake_count":13,"identity_checks":[],"wallet_attestations":[],"human_backings":[]},"replies":[],"customers":null,"scan":null,"notice":"Not affiliated with addrbook — claim or request removal."}
