{"slug":"2s-46d489f7","name":"2s","summary":"Look up or search NAICS 2022 industry classification codes (US Census Bureau, public domain). Pass `code` for an exact NAICS code — 2–6 digits or a combined sector like 31-33 — and get its official title, hierarchy path, full official description, activity index terms, and direct child codes. Or pass `query` for free-text search (e.g. 'software publishers', 'coffee shop') over titles plus the official ~20k-entry activity index → ranked candidate codes, optionally filtered by `level` (2=sector … 6=national industry). Ground truth for industry coding in KYC, business registration, government filings, and ERP vendor/customer setup.","status":"live","indexable":true,"listed_since":"2026-10-25T17:53:37.864367Z","sources":[{"source":"x402_bazaar","external_id":"https://2s.io/api/business/naics","owner_address":"0x2b6d4988db4723e6908db86ab2b8dfbc51fc32c5","seen_at":"2026-11-02T19:16:59.341372Z","removed_at":null}],"endpoints":[{"url":"https://2s.io/api/business/naics","host":"2s.io","protocol":"x402","state":"live","last_probe_at":"2026-11-02T03:28:15.053260Z","last_ok_at":"2026-11-02T03:28:15.053260Z","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/business/naics","network":"eip155:8453","scheme":"exact","rail":"exact","asset":"0x833589fcd6edb6e08f4c7c32d4f71b54bda02913","coin":"USDC","asset_label":"USD Coin","amount":"2500","pay_to":"0x2b6d4988db4723e6908db86ab2b8dfbc51fc32c5","observed_at":"2026-11-02T03:28:15.053260Z"},{"endpoint_url":"https://2s.io/api/business/naics","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","scheme":"exact","rail":"exact","asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","coin":"USDC","asset_label":"USDC","amount":"2500","pay_to":"TW6ntaGzvj63ZgPjszd4FCGmVTGfzv1MAYZbjYcyWhn","observed_at":"2026-11-02T03:28:15.053260Z"}],"usage":{"source":"x402_bazaar","unique_payers_30d":2,"paid_calls_30d":2,"last_paid_at":"2026-10-27T09:44:56.459Z","reported_at":"2026-11-02T19:16:59.341372Z"},"assessment":{"method":"2026.10.2","checks":[{"id":"answers","state":"pass","reason":"Answered a check 10 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 7 days; 30 are needed."},{"id":"real_customers","state":"fail","reason":"2 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":"2026-11-02T00:30:33.208736Z"},"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."}
