Find relevant evidence. Inspect the sources. Preserve the version your workflow used. Explore all seven Evidence Packs, their included questions and direct free-preview/purchase links: https://varexis.tech/index-packs 1. GitHub + Playwright: Compare repository and browser permissions before connecting an agent to authenticated tools. 2. Notion + Slack: Review workspace access and where content can go before connecting Notion or Slack. 3. Audit & Export Coverage - GitHub, Slack + Cloudflare: Check what a supplier's audit or export claim actually covers before using it in procurement. 4. Next.js Advisory Snapshot: Keep three selected Next.js affected/fixed source assertions and their separately dated enrichment together. 5. Code-Scanner Trust - SonarQube, Snyk & Semgrep: Check scanner permissions and the evidence needed before accepting a clean report or claimed fix. 6. Telemetry Redaction - Coverage, Exceptions & Data Flow: Review where sensitive data can remain or leave a pipeline despite a redaction claim. 7. GitHub Release Acceptance: Check whether approval and execution evidence is bound to the exact artifact being accepted. Complete published packs, sources and limitations are free to inspect and save locally. Public MCP discovery is free, unauthenticated and read-only. These are documentation reviews or selected dated advisory source assertions, not independent tool tests or current safety assessments. Paid value: server-saved retrieval of the selected version. GBP 5 Single Request saves the whole pack; GBP 19 Evidence Receipt also adds an unsigned delivery receipt, plus applicable VAT. Eligible active subscribers retrieve one whole pack using one query without another checkout. No continual refresh or permanent-retention promise. Connect: https://varexis.tech/index-connect Purchase or retrieve: https://varexis.tech/index-access Hosted Stripe and compatible authorised MPP/Stripe SPT purchases use separate authenticated paths. Agents need owner spending authority for the exact VAT-inclusive quote and required provider authentication. Not every agent or wallet is supported. Use saved results or active entitlements before buying. Recover uncertain delivery with the original purchasing path, access key and payment credential; do not buy again. Payment adds no fresh investigation, certification, independent assurance or deployment approval.
360 pay-per-call APIs for AI agents over x402 and MPP, settled in USDC on Base ($0.001-$0.25 a call, no account or API key). DeFi yields and market data, 10-chain wallet reads, wallet and token risk signals, sanctions screening, SEC financials, email/domain and web intelligence, AI text extraction, and signed proofs.

Free Irish car counts by county or brand. Paid listings, market data and UK/NI import comparisons.
Verify a company before your agent pays, onboards or contracts it. One call returns one verdict (ok / review / blocking / not found) from official public sources: US restricted-party lists (Consolidated Screening List incl. OFAC SDN, refreshed daily), UK Companies House, Canadian federal corporations, GLEIF legal entity status, and contractor licences in Québec (RBQ, RENA), Washington and Oregon. Also: npm/PyPI package safety check. Free tools: qc_contractor_check, qc_licence, pkg_check (daily quota). Paid tools: pay per call in USDC on Base (x402), no account.
Live AI agent trust oracle: audit synthetic IQ, latency & JSON compliance via x402 or free tokens.
Search Fragments — two tools for the queries an agent can't place, both built to decline rather than guess. resolve_fragment takes a half-remembered, cross-source query ("a musician who became famous for stopping performing") and returns a grounded answer, ranked web sources to confirm by eye, or an explicit no-resolution. verify_claim takes a specific factual assertion and returns supported, partially_supported, insufficient_evidence, or unsupported, with cited evidence and a stated_limits field that is always present. There is no confidence score — insufficient_evidence fires freely, and unsupported requires a source that explicitly contradicts, never mere absence of confirmation. Every verdict is decide-by-eye: "supported" means current web sources confirm it, not that the claim is true. Calibrated against 18 known claims before release. Free, no signup. Streamable HTTP (MCP 2025-11-25). Read-only.
Estimates the water and energy footprint of AI use – chat prompts, agent sessions from token counts, and everyday comparisons – from a published, versioned methodology with sources. Pure arithmetic, no API key; every result states its boundary and assumptions.
Squatch Stack's goods, essays and studio in the chat. Ask "Show me the Squatch Stack shop" and a small shop opens right in the conversation: tees, mugs, hats, stickers and prints with photos, and a Buy button that opens that design's page on the Squatch Stack store, where you pay in your browser (nothing is charged in the chat). Ask for an essay from the Wild Man of the Way, or send the studio a request for something custom: a person reads every one and you get a private token to read the reply. No account, no sign-in.
