  There are no tiers, subscriptions or quotas. Pricing is the product: the amount a
  caller names in a bid IS the price of the call, settled per-request in USDC over
  x402. Reads are free. Confirmed live — an unauthenticated POST /api/bid returns a
  402 priced at the named amount (finops/ontopx402-x402-challenge.json shows the $1
  minimum challenge).
