Vextorium MCP — 200+ pay-per-call APIs for AI agents

200+ pay-per-call data APIs for AI agents: official statistics and economic data, crypto prices, compliance checks, public records and web/data utilities. Connect over Streamable HTTP; no service API key, signup or subscription. See the live catalog for the exact current count and available services.

MCP endpoint: https://api.vextorium.com/mcp

Try it free

Connect your remote MCP client to https://api.vextorium.com/mcp and ask it to call current_date. It returns the live date and local time in Europe/Madrid, plus a UTC timestamp. No wallet, account or API key is needed.

Then explore the catalog with search_services and service_details, both free. Paid services are separate and require an appropriate payment client.

Tools

The HTTP catalog currently lists 244 routes; 242 are available through MCP. /v1/my-ip and /v1/ping are HTTP-only because their results refer to the HTTP client's IP. These are services exposed through call_service, not hundreds of separate MCP tools.

Available data and tools

• Economy: central-bank rates, inflation, FX, Treasury yield curves, economic calendar and official statistics.
• Companies and public records: SEC filings and financial data, EU and Spanish public records, tenders and grants.
• Crypto prices and calculations: prices by ticker, conversions, portfolio valuation, PnL and risk calculators.
• Compliance: sanctions screening, wallet sanctions checks, LEI, VAT/VIES and IBAN validation.
• Web and data utilities: DNS, SSL and security headers, JSON/CSV tools, text utilities, regex and JSONPath.
• Science and public data: weather, earthquakes, research and reference lookups.

The live catalog is authoritative. Older token-safety, Hyperliquid and XRPL node-data services are not advertised here because they are absent from the current catalog.

Connect

Add the remote server in Claude, Cursor or another MCP client:

{

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

The three free tools work without a wallet. Paid calls require an x402-capable buyer client that supports the selected network; adding an MCP URL alone does not enable payment.

MCP payments use USDC on Base, Solana, Polygon, Optimism, Arc or Stellar. The HTTP API also accepts RLUSD or XRP on the XRP Ledger. XRPL payment options are not exposed over MCP. Consult the current payment challenge and buyer guide before paying.

Plain HTTP: send a JSON body to POST https://api.vextorium.com/v1/ . An unsigned request returns HTTP 402 with the price and payment options. Service failures before settlement are not charged; if settlement is attempted but its result is uncertain, reconcile before paying again as explained in PAYMENTS.md.

Independent route check

PayAPI Market lists Vextorium's ECB rates history route. Its published check records a $0.003 USDC test payment on Base on 2026-10-23 for POST /v1/ecb-rates-history. This verification covers that route and payment network only.

Data and privacy

Inputs are processed in memory. Payment records are retained; for selected services returning public-source data, the delivered response and its hash are also retained as proof of delivery. Responses containing customer text, secrets or personal data are not retained. See the privacy policy and terms.
