Skavio LLC provides 18 hosted MCP tools for native Circle USDC payments via x402 v2 on Base and Solana: transaction verification, recipient/amount matching, blockchain evidence PDFs, DNS/TLS audits and agent utilities. Discovery and status tools are free; paid MCP calls require explicit buyer wallet authorization. The separate standalone Base-only HTTP APIs include USDC Verify (0.02), Match (0.03), Evidence PDF (0.05), and four DeepSeek-only web operations: Fetch (0.01), Search (0.02), Extract (0.02), Extract + Analyze (0.03 USDC). Those HTTP routes are not additional MCP tools. Evidence PDFs are not tax invoices.

Pay-per-call tools for AI agents: web page reader, prompt-injection/PII/secret scans, email and domain checks. 20 free calls a day. exelal >_ is a remote MCP server of small, single-purpose tools that agents call and pay for per call. No signup is needed: the cheap tools include 20 free calls a day, a free personal key at exepal.com/key gives each person their own 20, and paid calls settle in USDC on Base via x402 or from prepaid credit. A call that fails is never charged.
Objective Trust ranks MCP endpoints before the caller pays them. Tools: set_objective (free), rank_tools_for_task (API key or $0.005 x402), record_outcome (free). Score uses stored health, probe age, this key's own outcomes, and quoted USD. Sponsored, featured, and click_count are excluded from the score. The caller calls the chosen mcp_url and pays that server. Connect at https://agentshare.dev/mcp/objective-trust.

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/.
