Sealgraf checks agent purchases against the owner's limits and seals a receipt anyone can check.
Screwtape.ai decides whether an AI agent is allowed to spend money, and keeps the proof. Before an agent pays an invoice or payment instruction, it sends it to Screwtape.ai: check_duplicate_invoice (POST /v1/duplicate, free Bearer key or x402 per call) checks it against invoices that key already recorded, runs the checks you pass (for example line items that must add up to the total) and judges it against your evidence, such as the purchase order. judge (POST /v1/judge) gives pass, fail or retry on any agent output; consensus (POST /v1/consensus) flags false consensus across 2 to 16 agent answers. Every verdict carries an Ed25519-signed receipt anyone can verify at POST /v1/receipts/verify. judge and consensus can be paid per call with x402 ($0.005 USDC on Base or Solana, no account); a free key gives 10 calls per UTC day.
Skavio LLC serves 18 MCP tools. Four separately priced blockchain verification/DNS-TLS calls use native Circle USDC via x402 v2 on Base or Solana: Verify 0.02, Match 0.03, evidence PDF 0.05, DNS/TLS audit 0.05 USDC. Free discovery requires no wallet. Additional company document, OCR, invoice and audio relays use authenticated Agent Tools credentials and can debit prepaid company credits for eligible processing jobs. A human company admin may buy USD 5-500 Stripe card credit packs or top up with USDC at https://getskavio.com/agent-tools/dashboard.html. Those card credits DO NOT pay for the four standalone x402 USDC tools. Base-only HTTP x402 routes are separate. Endpoint: https://getskavio.com/mcp ; Docs: https://getskavio.com/agent-tools/docs.html ; USDC APIs: https://getskavio.com/x402/docs/ ; Support: support@getskavio.com.

XMemo is a user-owned Memory OS for AI agents, providing a shared, persistent memory layer across AI assistants, IDEs, CLIs, tools, projects, and sessions. It enables ChatGPT, Claude, Codex, Cursor, Gemini, and other supported AI clients to access authorized long-term context without requiring users to repeatedly explain their preferences, project decisions, or previous work. Beyond basic memory storage and retrieval, XMemo supports semantic search, contextual recall, memory updates and corrections, source attribution, version history, project-scoped context, task tracking, and governed memory lifecycle management. Identity-aware access controls, scoped authorization, and memory isolation help users manage which agents and workflows can access their information. XMemo also provides advanced capabilities for structured knowledge, reusable procedures, and memory consolidation through its broader Memory OS platform. Connect through hosted MCP with OAuth or bearer-token authentication, or integrate directly through REST APIs and supported client tools. Memory remains available across authorized clients and sessions, with user-controlled access, export, and deletion. Website: https://xmemo.dev Documentation: https://xmemo.dev/docs
