Data
Index identifiers, the dissemination schedule, and every figure the Index publishes, as files and as a public interface. No registration, licence or key is required.
I — Variants
Each variant is calculated from the same constituents and the same divisor, converted at the exchange rate of the day or calculated without dividends reinvested. Currency variants start from the US dollar level on 19 September 2026 and move with their own exchange rate thereafter; on that date all variants are equal by construction.
| Reading | Level | Day | Basis | Note |

II — Identifiers and dissemination
III — Files
Comma-separated files, rewritten after each official close.
IV — Interface
Every page on this site is drawn from these endpoints. They are served from the same address, require no authentication, and are updated as the Index is calculated.
V — Products
No fund, note or certificate tracks the Index, and no licence to do so has been granted. The Index is published for reference only and is not an offer, a recommendation, or an invitation to invest.

Community products are identified here. The Index does not calculate or administer them, and their value is not the level of the Index. More on the coin: $IDX.
