Drop-in EU AI Act compliance for LangChain & CrewAI. Equip your autonomous swarms with 19 A-graded MCP tools for Zero-Knowledge auditing, NIP-98 security, and L402 micropayments. 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.

SnapRender gives AI agents eyes on the web through a hosted MCP server. Send a public URL and get the page back as an image, a PDF or clean markdown, with no browser to run or maintain. Capture the viewport or the full page as PNG, JPEG, WebP or PDF, at desktop size or with a phone, tablet or laptop preset, in light or dark mode. Ads and cookie banners are removed by default, and you can hide elements or click one before the capture. extract_content reads the same page as markdown, text, article, links or metadata, so an agent can see a page and read it in one session. Made for monitoring and client work: batch up to 50 URLs in one job, check the cache for free before spending a capture, share signed links that render without an API key, and get webhooks when a batch finishes or a scheduled capture spots a change. Track competitors' pricing and landing pages, or send clients current screenshots of their sites. Connect with OAuth (Google, GitHub or email) or an API key. Works with Claude, ChatGPT, Cursor, VS Code and any MCP client. Free plan: 200 screenshots a month, no credit card. Paid plans from $9 a month for 2,000 up to $199 a month for 200,000.
