Technology intelligence feed for AI agents: tech stack, compliance, security.
VPN, proxy, Tor, hosting and CDN detection for any IP address, from the VPNDetection API.
Pre-trade token safety check for AI agents. Simulates a sell before you buy, then returns one low/medium/high/unknown verdict with the signals behind it: sellability, buy/sell tax, liquidity depth, pair age, same-ticker impersonation, owner powers from bytecode. Ethereum, BSC, Base, Solana. Fail-closed - a check that cannot run answers unknown, never low. Publishes its own measured error rate with the benchmark harness in the repo. Free, no signup, no API key, MIT.
Let your AI agent pay for APIs and data without handing it your money. In ChatGPT, Claude or Grok, the agent finds paid x402 APIs (with each seller's payout record from x402 Doctor) and asks to pay; you approve and sign each payment in your own wallet: MetaMask or Coinbase Wallet (USDC on Base), Phantom (USDC on Solana) or Xaman (RLUSD on the XRP Ledger). Fizzl checks every payment before you sign and every paid answer for hidden instructions. Fizzl never holds your keys. Free to start.
Block an action a signed mandate does not permit: amount, payee, audience, currency, window, intent.
Runtime permission, approval, and audit layer for AI agent tool execution.
DMARC monitoring and report analysis with SPF/DKIM diagnostics. Connect your Suped account to inspect monitored domains, email authentication issues, DMARC records and original report XML. Add domains for monitoring and create client organizations as an authorized MSP administrator. Access follows your Suped permissions. Adding a domain does not change DNS records; tools cannot resolve or dismiss issues.
Check dependencies for known CVEs with EPSS and CISA KEV context. Read-only; free API token.
Free website privacy scanner for pre-consent cookies, trackers, consent, policy, and HTTPS/TLS.
Verify an AI agent artifact: schema, emptiness, provenance and mandate authority, Ed25519-signed.

Source-linked evidence and reusable local checks for agent integration and review. Explore seven free evidence packs and three executable products, with questions, demonstrations and direct preview/purchase links: https://varexis.tech/index-packs Agent Tool Admission & Permission Control — GBP 49 + applicable VAT, one time. Supply local JSON declarations for GitHub, Playwright, Notion or Slack. The Node.js24 executable compares actions, resources, recipients, authority and inventory changes, returning a structured gap report. Free demonstration: https://varexis.tech/varexis-index/examples/agent-tool-admission/DEMONSTRATION.txt Agent Audit & Evidence Coverage — GBP 79 + applicable VAT, one time. Supply a declared event/evidence inventory. The local executable checks identity/authorization/action/outcome references and missing capture, export, retention or recovery coverage. Free demonstration: https://varexis.tech/varexis-index/examples/agent-audit-coverage/DEMONSTRATION.txt Each standalone licence is for one buyer or legal entity's internal staff, agents and CI use. No customer declarations are uploaded. No redistribution, external API resale, updates, monitoring or support SLA. Existing snapshot offers and subscriptions do not include these two licences. Checks concern supplied declarations; no live-permission inspection, enforcement, proof that records exist or certification. Seven complete evidence packs stay free: GitHub + Playwright permission boundaries; Notion + Slack access/data handling; GitHub/Slack/Cloudflare audit/export coverage; three dated Next.js advisory assertions; SonarQube/Snyk/Semgrep scanner trust; telemetry redaction gaps; GitHub release acceptance. These are dated documentation reviews or frozen source assertions, not independent tool tests or current safety assessments. Existing GBP 5 Single Request saves a version-bound public pack, or delivers the original Agent Tool Evaluation & Integration executable kit. GBP 19 Evidence Receipt also adds an unsigned delivery record. Plus applicable VAT. Eligible Research (GBP 29/month + VAT) and Developer/API (GBP 149/month + VAT) subscriptions retain their existing limits; an eligible pack or original kit uses one query. No continual refresh or permanent-retention promise. Public MCP discovery is free, unauthenticated and read-only: https://varexis.tech/mcp Connect: https://varexis.tech/index-connect Purchase or recover: https://varexis.tech/index-access Agent contract: https://varexis.tech/varexis-index/agent-payments.json Hosted Stripe and compatible authorised MPP/Stripe SPT purchasing use separate authenticated paths. Agents require owner spending authority for the exact tax-inclusive quote and required provider authentication; not every agent or wallet is compatible. Retrieve saved purchases or use eligible entitlements before buying. Recover uncertain payment with the original key and matching result endpoint; retain the original payment credential for supported retries. Never buy again to repair uncertain delivery. Payment adds no fresh investigation, independent assurance or deployment approval.
