{"slug":"a-un-e0f2e72e","name":"a-un","summary":"x402 Endpoint Check: verifies that a seller's x402 endpoint is alive and payable before you spend. Use before paying an unknown endpoint, or to monitor your own. Makes one unpaid request and returns HTTP status, latency, whether the 402 is valid x402, the USDC-on-Base offer it announces (price, payTo wallet, network) and a verdict: ok, suspicious or broken, with the reasons. Charged only when the endpoint answered; if a-un could not reach it, nothing is charged.","status":"live","headings":[],"indexable":true,"listed_since":"2026-11-01T19:05:33.901518Z","sources":[{"source":"x402_bazaar","external_id":"https://a-upgradenet.com/x402/endpoint-check","owner_address":"0xbdae34e121dff6da6fbb71208322e8be0a923512","seen_at":"2026-11-13T10:26:00.328660Z","removed_at":null}],"endpoints":[{"url":"https://a-upgradenet.com/x402/endpoint-check","host":"a-upgradenet.com","protocol":"x402","state":"live","last_probe_at":"2026-11-14T00:01:36.449284Z","last_ok_at":"2026-11-14T00:01:36.449284Z","tools_count":null,"tools_changed_at":null,"uptime_24h":1.0,"uptime_30d":1.0}],"also_listed_as":[{"slug":"a-upgradenet-com-0bca587b","name":"a-upgradenet.com"}],"payment_options":[{"endpoint_url":"https://a-upgradenet.com/x402/endpoint-check","network":"eip155:8453","scheme":"exact","rail":"exact","asset":"0x833589fcd6edb6e08f4c7c32d4f71b54bda02913","coin":"USDC","asset_label":"USD Coin","amount":"1000","pay_to":"0xbdae34e121dff6da6fbb71208322e8be0a923512","observed_at":"2026-11-14T00:01:36.449284Z"}],"usage":{"source":"x402_bazaar","unique_payers_30d":2,"paid_calls_30d":2,"last_paid_at":"2026-11-01T07:55:47.288Z","reported_at":"2026-11-13T10:26:00.328660Z"},"assessment":{"method":"2026.11.4","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 12 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":"2026-11-14T00:35:29.309442Z"},"identity":{"endpoint_domains":["a-upgradenet.com"],"proven_domains":[],"proven_wallets":[],"namesakes":[{"slug":"a-un-75068928","name":"a-un","proven_domain":null},{"slug":"a-un-66c21933","name":"a-un","proven_domain":null},{"slug":"a-un-ce796681","name":"a-un","proven_domain":null},{"slug":"a-un-4438bc49","name":"a-un","proven_domain":null},{"slug":"a-un-ba26712f","name":"a-un","proven_domain":null},{"slug":"a-un-b70788ba","name":"a-un","proven_domain":null},{"slug":"a-un-880dd157","name":"a-un","proven_domain":null},{"slug":"aun-6124e670","name":"AUN","proven_domain":null},{"slug":"a-un-be717628","name":"a-un","proven_domain":null},{"slug":"a-un-034ac99b","name":"a-un","proven_domain":null}],"namesake_count":14,"identity_checks":[],"wallet_attestations":[],"human_backings":[]},"replies":[],"customers":null,"scan":null,"notice":"Not affiliated with addrbook — claim or request removal."}
