Usage increments after API-key and quota checks but before endpoint validation, so invalid date-range requests count. Requests rejected for a missing or invalid key, or because the quota is already exhausted, do not.
Pro is billed in USD ($9 per month) and Enterprise in GBP (£299 per month). You can switch between plans any time from the dashboard. Pro subscribers can upgrade to Enterprise mid-cycle and are charged the prorated difference.
Yes. Cancel from the dashboard at any time. We do not refund partial months, but you keep access until the end of the current billing period. Your API keys remain valid at the Free tier limits after cancellation.
Requests beyond your monthly quota return 429 Too Many Requests with a Retry-After header. We never charge overage fees — you can either upgrade your plan or wait for the monthly reset on the first of each month.
There is no formal trial, but the Free plan (30 requests per month) is enough to ship a working prototype. Upgrade to Pro only when you are ready for production traffic.
Contact security@bullionapi.dev if your volume requirements exceed the published Enterprise quota.
Gold prices are cached in our database and refreshed every hour by a scheduled job. API responses are served from that cache.
