{"slug":"research-halowerk-com-v1-grounding-score-39e04f80","name":"research.halowerk.com/v1/grounding-score","summary":"Splits the answer into sentences and measures, for each one, how much of it is covered by the supplied sources. Coverage is asymmetric on purpose: the question is what share of the statement appears in the source, so a long source can fully cover a short claim, and it combines single-word overlap with word-pair overlap because the same words in a different order can mean something else. Two checks override coverage and this is the point of the endpoint.","status":"live","headings":[],"indexable":true,"listed_since":"2026-11-02T19:30:31.871508Z","sources":[{"source":"x402_bazaar","external_id":"https://research.halowerk.com/v1/grounding-score","owner_address":"0x2880edfff13100677bf97a3cbdf3bc34771c4e5e","seen_at":"2026-11-13T10:28:19.478280Z","removed_at":null}],"endpoints":[{"url":"https://research.halowerk.com/v1/grounding-score","host":"research.halowerk.com","protocol":"x402","state":"live","last_probe_at":"2026-11-13T07:05:29.927360Z","last_ok_at":"2026-11-13T07:05:29.927360Z","tools_count":null,"tools_changed_at":null,"uptime_24h":1.0,"uptime_30d":1.0}],"also_listed_as":[{"slug":"research-halowerk-com-24cf1386","name":"research.halowerk.com"}],"payment_options":[{"endpoint_url":"https://research.halowerk.com/v1/grounding-score","network":"eip155:8453","scheme":"exact","rail":"exact","asset":"0x833589fcd6edb6e08f4c7c32d4f71b54bda02913","coin":"USDC","asset_label":"USD Coin","amount":"2000","pay_to":"0x2880edfff13100677bf97a3cbdf3bc34771c4e5e","observed_at":"2026-11-13T07:05:29.927360Z"}],"usage":{"source":"x402_bazaar","unique_payers_30d":1,"paid_calls_30d":1,"last_paid_at":"2026-11-02T14:51:08.761Z","reported_at":"2026-11-13T10:28:19.478280Z"},"assessment":{"method":"2026.11.4","checks":[{"id":"answers","state":"pass","reason":"Answered a check 5 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 10 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":"2026-11-13T00:28:01.244675Z"},"identity":{"endpoint_domains":["halowerk.com"],"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."}
