Open AI models through one OpenAI-compatible API: chat, live model list, prices and cost estimates.
SimFuse is a travel eSIM storefront covering 200+ countries and regions. This connector lets an AI assistant plan a trip, compare live prices and open a checkout for eSIM data. Browsing needs no authentication. What it does: - plan-trip: give the stops (country code and days in each) and it compares one plan covering the whole route against one plan per country against a mix, on live prices, then flags the cheapest complete option and lists any country it cannot cover. - list-destinations: search every country and region SimFuse sells for, with the cheapest plan price per destination. - list-plans and get-plan: browse a destination's plan ladder, filter by data amount, validity and price, and inspect a single plan in detail. - get-plan-coverage: check every country a plan works in before buying. - create-checkout-session: open a checkout for the selected plans at frozen prices. Nothing is charged by that call; payment, completion and cancellation happen over the agentic HTTP API with the returned key. Good to know: prices come back in minor units of the currency you ask for, data allowances are in megabytes, and quotes are offers rather than reservations, so the charged total is computed at checkout. Operated by Qorinx OÜ. Buy directly at https://simfuse.app, agent documentation at https://simfuse.app/agent/.

Search, filter, count and sum Australian government open data, with every version kept.
Ask questions about Claude Code, Cursor, Codex and MCP — get answers grounded in their official docs, with citations. A hybrid RAG service that AI agents call through two MCP tools (or over REST). It indexes ~600 pages of official documentation, refreshes itself daily, and every design choice is backed by an experiment.

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. Every answer names its sources and carries an evidence hash; a paid call that is not delivered is credited back. Built and run by UnyKorn LLC.
Measured share of answer for 24 crypto and Web3 brands. An open dataset, not an audit of your site.
Measured share of answer for 20 SaaS brands. An open dataset, not an audit of your site.
Signed, traced record of what an npm package or file attempts when run, network included. No key.
Contract-change authorization for AI agents: preflight a change to an API or MCP contract, get a signed decision, and verify the receipt offline. Only a granted change can proceed.
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.
6 runtime tools: 2 HemmaBo tools, 2 host onboarding tools, and 2 VRP verification tools. Not an OTA.
Federated search of books and papers, BibTeX/RIS citations, open-access retrieval and reading.
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.
Source-linked research on U.S. judges, courts, cases, and judicial analytics.
