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.

# 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.

FlickDirect Inc’s free, read-only movie MCP server. Live version 1.5.6 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. Discover recent uploads from three FlickDirect YouTube channels and published podcast shows/episodes with bounded FlickRadio archive search.

Results preserve canonical source links and distinguish missing matches, unavailable sources and ambiguity. Shop inclusion is not a formal endorsement, and fetch time does not prove upstream currentness. No full articles, reviews, transcripts, scripts or photographs. Published YouTube watch/player links are supported where the host permits. Private operational diagnostics expire within seven days. No FlickDirect account or API key is required; AI-app availability and tool selection depend on the host.

Search Fragments is the gate before your agent answers. When a user half-remembers something your agent can't confidently place, one call returns a verdict: ORIGIN_OF_TRUTH (found and evidence-checked, with sources), PARTIAL_ORIGIN (leads worth following, not an answer) or NOT_REACHABLE (our search reached nothing; not a claim it can't be found). Your agent answers and cites, keeps looking, or says it can't place it, instead of inventing. Free, no signup. Also: verify_claim (check a specific factual claim against current sources) and submit_resolution_feedback.
Pre-payment checks for AI agents. Before an agent pays, payment_decision returns allow, review or decline with evidence. Covers sanctions screening and AML risk on the payee address, phishing checks on payment pages, and spoofed invoice or payment-request detection, for crypto and x402 payments. Free, no API key.

Courio prints a PDF (or plain/markdown text) and mails it as a real postal letter to supported countries worldwide: standard, tracked, registered, or registered with acknowledgement of receipt (proof of delivery, for legal notices). No account, no API key, no subscription. The agent checks coverage, gets a free quote (price fixed for 24 hours), creates the letter and shows the human a Stripe Checkout link. The letter is printed and posted right after payment, and the agent can follow it until delivery. Agents allowed to pay on their own can use the REST API instead: card via Stripe Shared Payment Tokens (Machine Payments Protocol), or USDC on Base via x402. Tools: - get_coverage: destinations, service levels and indicative prices (read-only) - quote_letter: free quote, nothing is mailed - send_letter: creates the letter and returns the payment link - get_letter_status: follow the letter (read-only) Docs: https://sendcourio.com/agents
