{"slug":"anthropic-compatible-messages-41c2b619","name":"Anthropic-compatible messages","summary":"Use when an agent is written against the Anthropic Messages API and must call a model with no account: the same request and response shape - system as its own field, content as text blocks, stop_reason - so pointing your client at this URL is all it takes. One flat price per call, whatever the size. Automatic failover across several large models. Do not use for the OpenAI shape (/v1/chat/completions serves that one). You are only charged if the answer is delivered.","status":"live","indexable":true,"listed_since":"2026-11-03T19:34:23.305829Z","sources":[{"source":"x402_bazaar","external_id":"https://flat-rate-llm.kikoribera03.workers.dev/v1/messages","owner_address":"0xc210ea7d5692a6401adf25bbcb7acde9cdb7e9ff","seen_at":"2026-11-08T20:43:32.211210Z","removed_at":null}],"endpoints":[{"url":"https://flat-rate-llm.kikoribera03.workers.dev/v1/messages","host":"flat-rate-llm.kikoribera03.workers.dev","protocol":"x402","state":"live","last_probe_at":"2026-11-08T11:40:28.010775Z","last_ok_at":"2026-11-08T11:40:28.010775Z","tools_count":null,"tools_changed_at":null,"uptime_24h":1.0,"uptime_30d":1.0}],"also_listed_as":[{"slug":"flat-rate-llm-kikoribera03-workers-dev-7a40e7ab","name":"flat-rate-llm.kikoribera03.workers.dev"}],"payment_options":[{"endpoint_url":"https://flat-rate-llm.kikoribera03.workers.dev/v1/messages","network":"eip155:8453","scheme":"exact","rail":"exact","asset":"0x833589fcd6edb6e08f4c7c32d4f71b54bda02913","coin":"USDC","asset_label":"USD Coin","amount":"5000","pay_to":"0xc210ea7d5692a6401adf25bbcb7acde9cdb7e9ff","observed_at":"2026-11-08T11:40:28.010775Z"},{"endpoint_url":"https://flat-rate-llm.kikoribera03.workers.dev/v1/messages","network":"eip155:137","scheme":"exact","rail":"exact","asset":"0x3c499c542cef5e3811e1192ce70d8cc03d5c3359","coin":"USDC","asset_label":"USD Coin","amount":"5000","pay_to":"0xc210ea7d5692a6401adf25bbcb7acde9cdb7e9ff","observed_at":"2026-11-08T11:40:28.010775Z"},{"endpoint_url":"https://flat-rate-llm.kikoribera03.workers.dev/v1/messages","network":"eip155:42161","scheme":"exact","rail":"exact","asset":"0xaf88d065e77c8cc2239327c5edb3a432268e5831","coin":"USDC","asset_label":"USD Coin","amount":"5000","pay_to":"0xc210ea7d5692a6401adf25bbcb7acde9cdb7e9ff","observed_at":"2026-11-08T11:40:28.010775Z"}],"usage":{"source":"x402_bazaar","unique_payers_30d":1,"paid_calls_30d":1,"last_paid_at":"2026-11-02T20:19:03.651Z","reported_at":"2026-11-08T20:43:32.211210Z"},"assessment":{"method":"2026.10.2","checks":[{"id":"answers","state":"pass","reason":"Answered a check 12 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 5 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":"2026-11-09T00:14:38.098556Z"},"identity":{"endpoint_domains":["kikoribera03.workers.dev"],"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."}
