VaultDrain Data

The numbers, clean, in your pipeline

The reconstructed five-year COMEX, LBMA and Shanghai vault series and every dealer premium quote we capture — the same numbers this site publishes — delivered as CSV or a simple JSON API. Built for newsletter writers, small funds and researchers who need the series, not a screenshot.

What you get

  • Full vault series. Daily COMEX registered and eligible, London holdings, Shanghai warrants — every row flagged live or reconstructed-estimate, so nothing gets mistaken for an exchange print.
  • Dealer premium quotes. Every captured quote with the all-in price, payment method, stock status and the spot price recorded at the moment of capture.
  • Retail tightness index. The current median premium, stockout rate and composite tightness index, plus 90 days of history (?dataset=tightness).
  • CSV or JSON. One URL, one key. Refresh as often as you like within fair use.

Legal & compliance

VaultDrain is an independent information and community site, not a broker, dealer, exchange, investment adviser, fiduciary, or research provider. Nothing on this site is financial, investment, trading, legal, or tax advice, an offer or solicitation, or a recommendation to buy, sell, hold, or trade any security, commodity, derivative, currency, or precious metal. Precious metals are volatile and may result in substantial loss. Conduct your own research and consult appropriately licensed professionals before acting.

Prices, exchange rates, vault inventories, and supply/demand figures come from third-party sources and are shown for information only. They may be delayed, estimated, revised, or wrong, and some figures (including historical vault snapshots, retail prices, premiums, and monthly forecasts) are illustrative estimates. Data labeled live may still be delayed by its provider. Vault categories and availability do not prove that metal is unavailable for delivery. Verify all figures with the named primary source before relying on them.

Triple-digit dates, price paths, ratios, days-of-supply figures, and other forward-looking statements are hypothetical scenarios, not forecasts or guarantees. Past performance does not predict future results. To the fullest extent permitted by law, VaultDrain provides the site “as is,” makes no warranty of accuracy, availability, or fitness for a particular purpose, and is not liable for losses arising from use of the site.

Dealer links may be sponsored or affiliate links, which can earn VaultDrain a commission without increasing your price. Inclusion is not an endorsement. Dealers control their own pricing, inventory, shipping, storage, returns, taxes, and compliance; review their terms and independently verify them before purchasing. External sites and quoted news remain the responsibility of their publishers.

Account and newsletter details are used to provide the requested services and operate the site; do not submit information you do not want processed for those purposes.
