FeedOracle Technologies — Engineering What Comes Next. Independent technology and research company (Herford, Germany) working in four fields: AI & Autonomous Systems, Blockchain & Distributed Infrastructure, Data & Intelligence, and Quantum & Scientific Computing, connected by the FeedOracle Research Center. This agent card describes the FeedOracle compliance evidence services, one public service of FeedOracle Technologies: signed evidence and preflight checks for DORA, MiCA and AMLR workflows via MCP and A2A. Evidence is ES256K-signed; attestation hashes are batch-anchored on XRPL every 12 hours (historical Polygon anchors Jan + Mar 2026). Live service metrics: https://feedoracle.io/data/feedoracle-metrics.json. AgentNOMOS (agentnomos.com) and ToolOracle (tooloracle.io) are independent developments of FeedOracle Technologies. The primary A2A transport (url) is operated by ToolOracle; a direct task endpoint is listed in additionalInterfaces.
