{"slug":"2s-12f3c6a4","name":"2s","summary":"List the official holidays for a country and year, with exact observed dates including substitute days (e.g. a Saturday July 4th observed on Friday). Query: country (ISO 3166-1 alpha-2, 200+ supported), year, optional region (subdivision code like CA for US-California or BY for DE-Bavaria), optional types filter (public, bank, school, optional, observance — comma-separated), optional lang (ISO 639-1) for localized names. Returns one item per holiday: { date (YYYY-MM-DD), name, type, substitute, rule }. Dates are computed from maintained per-country rules — including movable feasts and lunar-calendar holidays — so they stay correct year over year. Use for scheduling, delivery estimates, payment terms, and SLA math.","status":"live","indexable":true,"listed_since":"2026-10-25T17:53:23.482227Z","sources":[{"source":"x402_bazaar","external_id":"https://2s.io/api/calendar/holidays","owner_address":"0x2b6d4988db4723e6908db86ab2b8dfbc51fc32c5","seen_at":"2026-10-26T19:25:49.029927Z","removed_at":null}],"endpoints":[{"url":"https://2s.io/api/calendar/holidays","host":"2s.io","protocol":"x402","state":"live","last_probe_at":"2026-10-26T09:56:13.343470Z","last_ok_at":"2026-10-26T09:56:13.343470Z","tools_count":null,"tools_changed_at":null,"uptime_24h":1.0,"uptime_30d":1.0}],"also_listed_as":[{"slug":"2s-io-49c1cd49","name":"2s.io"}],"payment_options":[{"endpoint_url":"https://2s.io/api/calendar/holidays","network":"eip155:8453","scheme":"exact","rail":"exact","asset":"0x833589fcd6edb6e08f4c7c32d4f71b54bda02913","coin":"USDC","asset_label":"USD Coin","amount":"2500","pay_to":"0x2b6d4988db4723e6908db86ab2b8dfbc51fc32c5","observed_at":"2026-10-26T09:56:13.343470Z"},{"endpoint_url":"https://2s.io/api/calendar/holidays","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","scheme":"exact","rail":"exact","asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","coin":"USDC","asset_label":"USDC","amount":"2500","pay_to":"TW6ntaGzvj63ZgPjszd4FCGmVTGfzv1MAYZbjYcyWhn","observed_at":"2026-10-26T09:56:13.343470Z"}],"usage":{"source":"x402_bazaar","unique_payers_30d":5,"paid_calls_30d":22,"last_paid_at":"2026-10-25T14:34:15.438Z","reported_at":"2026-10-26T19:25:49.029927Z"},"assessment":{"method":"2026.10.1","checks":[{"id":"answers","state":"pass","reason":"Answered a check 4 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 0 days; 30 are needed."},{"id":"real_customers","state":"fail","reason":"5 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":"2026-10-26T14:48:28.661830Z"},"identity":{"endpoint_domains":["2s.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."}
