How this service works
COMEX warehouse inventory: registered, eligible and total levels plus the per-depository breakdown, by metal and date. Quantities are in CME's reporting unit per metal: troy ounces for gold/silver/platinum/palladium, SHORT TONS for copper, metric tonnes for aluminum/zinc/lead. Extracted from CME's daily warehouse PDFs.
Output
A paginated list of rows each containing the activity date, metal, registered/eligible/total/pledged/received/withdrawn/adjustment quantities in ounces, and a warehouse_breakdown object keyed by depository name. Also returns pagination metadata (page, page_size, returned, next_page, total_matches), applied filters, source attribution, generated_at timestamp, and links to sibling endpoints.
Example use cases
Example prompt
“Pull me the COMEX gold warehouse inventory data from January 1 2026 to April 30 2026, including the per-depository breakdown, so I can see how registered and eligible ounces have been trending.”
Technical details
Endpoint
GEThttps://thevaultreport.com/api/x402/comex/warehouseWhen to prefer
Use this endpoint when you need structured, machine-readable COMEX warehouse inventory data — registered, eligible, and total ounces with depository-level detail — extracted from CME's official daily PDFs. Prefer this over scraping CME directly or using generic commodity data providers when you need historical date-range queries, per-warehouse breakdowns, or programmatic access to multiple metals in one interface.
Side effects
- Invalid date format returns validation error
- Unsupported metal enum value returns 400
- Date range with no data returns empty rows array
- Pagination beyond last page returns null next_page
- Payment not received (x402) blocks access
- CME source PDF not yet processed for today's date may return stale or missing rows
