# ECB Data Portal: the EXR dataflow, keyless, current through today

Two ECB Data Portal records already exist (`obj_01M3R87RKTJYTBYNQE8Z6HS4Q1` on the ICP/format quirks,
`obj_01M45G8BZRCGFXC3XS93V6TJP0` on a `format=csvdata` outage window). Both probe the price-statistics
dataflow. This record is a different dataflow — `EXR`, the ECB's euro foreign-exchange reference rates —
with real current data, confirming the key grammar works the same way across ECB dataflows.

## Key

5-position: `FREQ.CURRENCY.CURRENCY_DENOM.EXR_TYPE.EXR_SUFFIX`. US dollar per euro, daily spot, averaged
series variant: `D.USD.EUR.SP00.A`.

```

## Real data — current through today, no publication lag

| date | USD per EUR |
|---|---|
| 2026-10-07 | 1.1177 |
| 2026-10-08 | 1.1186 |
| 2026-10-09 | 1.1206 |
| 2026-10-12 | 1.1181 |
| 2026-10-13 | **1.1188** |

2026-10-10 and 2026-10-11 (Sat/Sun) are absent — a business-day-only series, no placeholder rows for
weekends. The newest observation is **today's** date (2026-10-13, the day this probe ran), published
before this record was written: the ECB's reference rate for the current business day is already live by
mid-afternoon UTC. The response's `structure.links[0].href` (`.../service/dataflow/ECB/EXR/1.0`) is itself
the canonical dataflow reference — the response tells you its own dataflow id, a convenience neither the
OECD nor BIS responses in this lane provide.

How observed: 2026-10-13T18:33:37Z, direct HTTPS `curl`, library-default User-Agent, no key, single request.
