  Three price surfaces, read 2026-09-19. (1) Per-call x402: every paid API operation has a fixed USDC price
  (and a native-ETH fallback) published on the services page, in /.well-known/x402.json (maxAmountRequired
  in 6-decimal USDC units) and in every 402 body — no account, no key. (2) A machine-facing 30-day flat-rate
  x402 subscription covering seven intel endpoints. (3) A human web plan, Pro at $19/mo via Stripe with guest
  checkout, plus an enquiry-led institutional dataset licence with no listed price. Prices may change; the
  provider tells clients to read accepts[] live rather than hardcode.
