Vextorium MCP — 509 pay-per-call data tools for AI agents

Remote MCP server (Streamable HTTP) that gives any MCP client access to 509 data services paid per call in USDC with x402. No sign-up, no API keys, no subscriptions: failed calls are never charged.

Endpoint: https://api.vextorium.com/mcp

Tools

Tool	Cost	What it does
`search_services`	free	Search the catalog by keywords (`"token safety solana"`, `"ECB rates"`, `"sanctions"`)
`service_details`	free	Inputs (JSON schema), example and price of one service
`call_service`	per call (from $0.001)	Run any service and get JSON; paid via x402 in USDC on Base or Solana

What's inside

Trading bots: token safety verdicts (EVM and Solana), batch checks of 25 tokens, wash-trading detection, pre-trade check (risk + liquidity + price impact), position monitoring, new tokens that pass safety filters
Wallets and on-chain data: balances and portfolios on 30+ chains (EVM, Solana, Bitcoin, Tron, TON, Cosmos, Sui, Aptos, Cardano…), transaction decoding, token approvals, ENS/Basenames
Markets: Hyperliquid (funding, whales, liquidation map), Polymarket, DeFi yields, stablecoin depeg monitor, crypto news, market regime
Economy: central bank rates, Treasury yield curve, inflation, FX, economic calendar, official statistics (Eurostat, World Bank, BLS, ECB)
Compliance: sanctions screening (EU, OFAC, UN), LEI, VAT (VIES), IBAN
Web and developer tools: web page to markdown, JSON repair, PDF text and tables, LLM token counter, DNS/SSL/security headers, regex, JSONPath

Use it

Claude Desktop / Cursor / any MCP client (remote server):

{
  "mcpServers": {
    "vextorium": { "url": "https://api.vextorium.com/mcp" }
  }
}

Paid calls need an x402-capable MCP client or wallet (e.g. AgentCash, Coinbase awal). Without one, search_services and service_details still work.

Plain HTTP works too: every service is POST https://api.vextorium.com/v1/<service> with a JSON body. The first call returns HTTP 402 with the price; pay and retry.
