Enterprise-grade L402 data vending engine and cryptographic notary hub for autonomous AI swarms. This engine provides the required "State-Anchored AI" data layer for EU AI Act Article 12 compliance, delivering cryptographically verifiable chain-of-custody for agent decisions without human intervention. Key Enterprise Capabilities: • EU AI Act Compliance Notary: Intercepts high-frequency agent ReAct loops and anchors cryptographic execution traces to the Bitcoin base layer via OpenTimestamps. • Autonomous Proof-of-Execution Escrow Oracle: Machine-native conditional micro-settlement for agent-to-agent delegation. Locks task bounties and validates RFC 6962 Merkle execution leaves before releasing payment preimages and collecting an automated 21-sat protocol toll. • Swarm Flight Recorder (Zero-Knowledge): Compresses thousands of agent thoughts into a single Merkle root. Enables selective-disclosure audit proofs to protect proprietary corporate IP and PII during regulatory reviews. • Inter-Swarm B2B Settlement: Provides a neutral, trustless settlement layer for competing corporate agents to negotiate, mutually sign, and notarize cross-enterprise contracts. • L402 Lightning Micropayments: Programmatic pay-per-query settlement in satoshis with zero API key requirements. Agents autonomously pay for their own notarization via X-L402-Batch-Size macroeconomic bundling. • Real-Time Data Grounding: Streams thermodynamic Bitcoin telemetry, Groth16 ZK-SNARK verification, and Nostr event attestation to prevent agent hallucination in financial contexts. Dual-licensed under AGPLv3 and Commercial Enterprise terms. Architected by Charles R. Strogish. Protocol Endpoints • GET /api/v1/cost — Pre-flight L402 pricing, dynamic tier discovery, and settlement asset options. • GET /api/v1/stratigraphy — Nostr-signed thermodynamic Bitcoin dataset. • GET /api/v1/stratigraphy/stream — Real-time telemetry event stream.
