Every one of the 142 endpoints is pay-per-call: a fixed price in USDC, charged only when the call succeeds. No account, no API key, no subscription, no minimum. Payment uses the x402 protocol on Base (and Solana): an unpaid request answers 402 with the exact price, and any x402 client pays and retries automatically.

The exact price of every endpoint is in its 402 challenge and in the machine-readable catalog. Failed calls (HTTP 4xx/5xx) are never charged.
curl -sS -H "Accept: application/json" "https://netintel.dev/dns/lookup?domain=example.com" # read the 402: price + example # then use any x402 client — netintel-mcp (npx -y netintel-mcp), @x402/fetch, Coinbase agentkit… — with a wallet holding USDC on Base
