      Programmatic access to Bitculator market data. Every response carries the live monthly quota
      in X-Quota-Limit / X-Quota-Used / X-Quota-Remaining / X-Quota-Reset headers; a per-plan
      per-minute burst throttle (Free 30, Starter 60, Pro 120) sits in front of the monthly quota
      (Free 10k, Starter 50k, Pro 250k). Errors always use the stable
      {"error":{"code","message","details"}} envelope — match on error.code (validation,
      unauthenticated, not_found, plan_required, rate_limited). Webhook deliveries are signed
      Stripe-style via X-Bitculator-Signature (t=<ts>,v1=<hmac_sha256>).
