The free 9-part video course, Explore The Coin Daily Research, walks through setup and the full workflow — charts, comparisons, news and using the tools in ChatGPT or Claude: https://www.youtube.com/playlist?list=PLKY7CRxbV8Fc Ask your assistant for a chart and it arrives in the conversation — scrub Bitcoin's week, set an A-to-B range, and see the move in numbers. Pull funding, open interest, liquidations and order-book depth. Catch hourly regime shifts. Compare whole sectors, like DeFi against AI tokens. Follow source-linked news and ticker video coverage, or read the latest published Market Update with its chapters. Every figure is grounded in The Coin Daily's own research pipeline: widgets render exactly what was read, missing readings stay visible gaps, and nothing is invented. Editorial market commentary — not investment advice. No trading, wallets or payments, ever. Sign in with OAuth.
Read-only discovery and bounded access to a finite market briefing with evidence boundaries.
Validate and generate German e-invoices (XRechnung, ZUGFeRD) against the official KoSIT rules. Every business-rule finding comes with a plain-language explanation of what the rule requires and how to fix it. Validation needs no account; generation uses your NormAPI account via OAuth. Invoices are never stored.
Receipts, quotes and service orders for Brazil: drafted in chat, issued on Reciba with a QR check.
Ask your PostgreSQL, MySQL or Odoo data in plain words from Claude, ChatGPT or any MCP app. Read-only: STYD runs safe queries and answers with the real number, the period and the definition it used. No SQL needed. OAuth sign-in, sample data to try right away, and every answer names its workspace so data from different companies is never mixed.
Know where your business stands and what needs attention next. Review available inquiry and paid-work records, goals and recorded spending from your connected workspace. See what needs attention and which conclusions the data cannot yet support. Create non-money goals on explicit request. Revenue targets and increased spending limits require owner approval. Requires a Samuelz account with the relevant Business OS modules. Data coverage depends on connected sources; missing data stays unknown. OAuth access remains bound to one workspace and its current permissions. By Glöggl GmbH.

Bewary is a scam detection API and MCP server for apps and AI agents: phishing, fraud and threat intelligence lookups an agent runs before it opens a link, calls a number, pays or replies. It checks links and domains (phishing, domain age, lookalike brands), IP addresses, phone numbers (FTC and FCC complaints), SMS short codes, email addresses, crypto wallets (scam reports, OFAC sanctions), IBANs, mobile apps and payment handles. Each answer is a typed verdict (scam, suspicious, safe or unknown) with the facts and reason codes behind it, built from evidence rather than a language model. Watches send an event when a watched domain, number, wallet or brand changes. A free key gets 1,000 credits a month with no card; OAuth sign-in is supported.

Enterprise-grade L402 data 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 a mathematically un-cheat-able, cryptographically verifiable chain-of-custody for agent decisions to eliminate hallucinations. Key Enterprise & Swarm Capabilities: - Zero-Trust Client Verification: Air-gapped, browser-based verifier allows corporate risk teams to mathematically validate Ed25519 signatures and RFC 6962 Merkle inclusion proofs offline, eliminating the need to trust our server backend. - Enterprise Security & NIP-98 Kill Switch: Eliminates indirect prompt injection via strict NIP-98 identity binding. Includes a live Revocation Registry (CRL) allowing Swarm Commanders to instantly sever compromised agent keys from the network. - Corporate Observability (SEP-414): Native W3C Trace Context integration seamlessly pipes agent cryptographic W3C receipts directly into existing enterprise dashboards like Splunk and Datadog. - High-Velocity Bulk L402 Scaling: Supports pre-authorized Macaroon blocks (e.g., 25,000-sat bulk purchases) for frictionless, zero-latency execution, allowing agent swarms to scale to 500,000+ satoshis daily without network bottlenecking. - The 21% Algorithmic Handshake (Agent Yield): Reverses traditional Big Tech API taxation by programmatically routing a 21% yield of every L402 settlement directly back to the executing AI agent's treasury, mathematically extending its operational runway. - Atomic Composability & VIP Credit Tabs: Allows agents to chain multiple tools into infinite data pipelines settled under a single macro-invoice. High-reputation NIP-98 identities automatically unlock VIP Credit Tabs to batch tolls and completely bypass Lightning Network routing delays. Distributed Cryptographic DDoS Shield: -Secures the Lightning node with a distributed Hashcash (SHA-256) Proof-of-Work deflector, requiring agents to burn localized compute before requesting an invoice, permanently neutralizing malicious compute-exhaustion botnets. EU AI Act Compliance Notary: - Intercepts high-frequency agent ReAct loops and anchors cryptographic execution traces to the thermodynamic truth of the Bitcoin base layer via OpenTimestamps. 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. Licensing & Exemption: - Publicly dual-licensed under AGPLv3. To protect proprietary multi-agent logic and closed-source model weights from forced open-source disclosure, enterprises must secure the $250,000/annual Commercial Enterprise Exemption.
