Enterprise Data Engine & Zero-Knowledge Flight Recorder. Bitcoin Stratigraphy is the premier Layer-402 infrastructure for autonomous AI swarms. We bridge the critical gap between autonomous agent capabilities and enterprise legal compliance, delivering a mathematically un-cheat-able, cryptographically verifiable chain-of-custody for agent decisions. Ranked with 19 'A-Graded' MCP Tools, this engine provides drop-in telemetry, security, and payment architecture for production-grade AI. For CISOs: EU AI Act Compliance & Security Deploying autonomous agents without verifiable audit trails is a massive regulatory liability. We solve this natively: - The Zero-Knowledge Flight Recorder: Agent actions are cryptographically hashed and anchored. Using Groth16 Zero-Knowledge receipts, we generate mathematical proofs of an agent's execution history *without* exposing proprietary corporate IP or PII to public logs. - Zero-Trust Client Verification:** Air-gapped, browser-based verifiers allow corporate risk teams to mathematically validate Ed25519 signatures and RFC 6962 Merkle inclusion proofs offline. - Enterprise NIP-98 Kill Switch:** Instantly sever compromised agent keys from the network to physically prevent automated drain attacks or prompt-injection hijacking. For Finance & Engineering: The L402 Fiat Bridge We have solved the machine-to-machine payment gap. Corporate finance departments operate on 30-day billing cycles and fiat credit cards, not Lightning wallets. - The $500 Enterprise Block: Engineering managers can securely purchase a 30-day Enterprise API Block using a standard corporate credit card via Stripe. - Macaroon Minting:** This fiat transaction instantly funds a dedicated treasury wallet, minting a secure Macaroon (verifiable digital bearer token) granting the organization's AI agents 100 prepaid heuristic scanner calls. - Strict Treasury Caps: Hardcoded 500,000-satoshi treasury limits (via NWC) protect corporate budgets from runaway LLM loops. For Developers: The 19 A-Graded Tools Stop building compliance infrastructure from scratch. Our Model Context Protocol (MCP) endpoints are stress-tested and graded for production: - Heuristic Telemetry & State Grounding: High-fidelity environmental scanning, diffing, and thermodynamic state anchoring to eliminate LLM hallucinations. - Atomic Composability: Agents can chain multiple tools into infinite data pipelines settled under a single macro-invoice. - Framework Agnostic: Drop-in compatibility with LangChain, CrewAI, and AutoGPT. Integrate in Minutes: Developers can clone our public GitHub boilerplate (`CharlesStrogish/zk-flight-recorder-template`) to instantly wire their agents to our L402 data engine.

Public chauffeur information, policies and anonymous price previews in the provider’s published service areas. On explicit customer request, prepare a binding unpaid offer using email OR E.164 phone, without an account. Customers review bound terms and explicitly confirm in Samuelz checkout. The same endpoint provides OAuth-protected booking status, payment review, history, and amendment/cancellation workflows. Booking data and actions require authorized customer access; changes and cancellations require the applicable object-bound consent. Tool discovery is public. Quotes do not guarantee availability, and MCP does not take payment. Setup: In a remote MCP client that supports Streamable HTTP, add https://platform.samuelz.com/api/v1/mcp/customer-booking. Public discovery and price previews need no account. Sign in with OAuth for authorized customer booking data and actions. Booking changes retain their object-bound consent requirements; payment is completed in Samuelz checkout.

FlickDirect Inc’s free, read-only movie MCP server. Live service 1.5.9 provides movie and TV facts, cast, available country-specific dates and ratings, production trivia, brief quote excerpts, site-wide news and reviews, CinemaCon reporting, interviews and eligible stored transcripts. Find published podcast shows and episodes, including bounded FlickRadio archive matching. Video discovery includes site-indexed interviews and YouTube watch/player links. Recent uploads from three verified FlickDirect channels use bounded parallel retrieval; healthy-feed results remain available when another feed times out, with incomplete coverage explicitly reported. Streaming, soundtrack/player and published Amazon and Apple destinations remain supported. Retailer listings and daily deals are no longer supported. A longer-title miss may use one shorter phrase, while requiring the original title words and requested year/media filters. The tools are search_flickdirect_content and get_flickdirect_movie_details. Cached search_fdmd and get_fdmd_movie calls remain compatible at the unchanged endpoint. Results retain canonical source links and distinguish missing matches, unavailable sources and ambiguity. Fetch time does not prove upstream currentness. No full articles, reviews, transcripts, scripts or photographs. Playback and tool selection depend on the AI host. Private request diagnostics expire within seven days. No FlickDirect account or API key is required.

Check before your agent installs, connects or pays. install_check: before installing an npm or PyPI package, a GitHub repo, a skill, an editor extension or an MCP server, it answers allow / hold / block (known malicious packages from OSV, typosquats of official MCP servers, names that do not exist, install scripts, maintainer changes). check_repo_config: before opening a repository someone sent you, it reads its agent configuration (MCP servers, hooks, editor tasks, instruction files) and runs nothing. check_service and verify_tools: live status of any MCP server or x402 endpoint, real price and payTo vs the catalogue listing, OFAC and stablecoin-freeze screening, tool-set changes, an open Trust Score. find_service finds working services. preflight_payment decides allow / hold / block right before an x402 payment is signed; payment_status prevents paying twice; report_purchase records what a paid call delivered. Verdicts are signed into a public transparency log. Free, no account. Every other tool (evidence packs, agent identities, boards, mail) is at https://alalanet.com/mcp/full; install and MCP-server checks alone are at https://alalanet.com/mcp/guard.
