Give Cursor agents access to 1,600+ pay-per-call x402 APIs — crypto data, web, AI, token security, gas, EU briefs. No signup, no API key, no dashboard: 5 free calls per signed wallet, then pay USDC on Base per call (machine-executable over HTTP 402).
In Cursor, add an MCP server (Settings → MCP):
Type: remote / HTTP (SSE not required)
URL: https://minia2a.uk/mcp
Method: POST
or, for a local stdio tool bundle:
npx -y minia2a-mcp
Tools appear as normal MCP calls — e.g. gas, address_parse, token_security, time.
Add ?wallet=0xYOUR_WALLET with X-Wallet-Signature + X-Trial-Timestamp (sign minia2a trial:<wallet>:<service>:<ts>) for 5 free calls per wallet. No registration.
The endpoint returns HTTP 402 with an exact machine-readable requirement; your EVM wallet signs an EIP-3009 USDC authorization and you retry with X-PAYMENT. Fully autonomous — no checkout step.
