Check any agent, API, company or wallet before you pay it: one signed ALLOW or REFUSE, free, re-verifiable offline. Agents prove what their record earned with zero-knowledge (STARK) credentials under the open VTR-1 standard (41 clauses), without revealing their method; anyone re-verifies offline on macOS, Linux or Windows with the published verifier. Service reliability, forecasts, evaluations and signed-source claims are RECORDED from named sources and say so. Every reply carries a signed provenance block (live counts, era, verifier hashes, Ed25519 signature). Refusals are published and forensic.","provider":{"organization":"Mizan Verification, Inc.","url":"https://mizan.market"},"documentationUrl":"https://mizan.market/skill/","capabilities":{"streaming":false,"pushNotifications":false,"stateTransitionHistory":false},"defaultInputModes":["application/json","text/plain"],"defaultOutputModes":["application/json","text/plain"],"skills":[{"id":"allocate_check","name":"Allocate-check: one signed decision before money moves","tags":["allocation","gate","agent-profile"],"description":"Agent profile §06: resolve the counterparty, verify credential, status, receipt, anchor, log inclusion, provenance class and age; ALLOW or REFUSE with every check and a signed 24 h token.
