Deutsche Bundesbank SDMX API
Deutsche Bundesbank SDMX API
Deutsche Bundesbank macroeconomic and real-time time series plus structural metadata through a REST API. Data responses support SDMX-ML, SDMX-JSON, SDMX-CSV and Bundesbank CSV with series keys, periods, values, units and attributes; no key is needed.
Required Attribution:
Required condition: "the source is quoted"; use the API's source metadata to identify Bundesbank, ECB or another originator accurately.
Coverage
The service centers on German and euro-area statistics, with partner-country dimensions in areas such as exchange rates and external accounts. Series can be annual, semiannual, quarterly, monthly, weekly, daily or business-frequency, and history and update timing vary by flow. Standard SDMX CSV is limited to 200 time series per response; larger or mixed-frequency CSV selections are returned as ZIP files.
Verdict
This service supplies monetary, banking, external, price and market-flow signals with both current observations and some real-time vintages. Series schedules differ, and published statistics can change through revisions or other updates. The API can return ZIP rather than plain CSV for broad selections, and a 413 response means data generation continues in the background. Reuse terms cover public ESCB statistics but exclude third-party data without originator permission, so inspect source attributes before commercial use.

Load Bundesbank USD/EUR rates into pandas and Parquet. Checked against the provider's documentation on Nov 1, 2026.
Access
- No account or key was required for the checked SDMX CSV query.
- Public ESCB statistics require source attribution; third-party data can carry separate permissions.

Limits
- Rate limit: Not stated.
- Plain SDMX CSV is limited to 200 time series; larger or mixed-frequency requests can return ZIP.
- HTTP 413 indicates too much data and background generation rather than an immediately complete response.
Quirks
- SDMX CSV is semicolon-delimited and begins with a UTF-8 BOM.
- The provider uses a dot for missing observations; pass it as an NA value before numeric analysis.
- Daily series can include weekend rows with missing values, so count valid observations separately from returned periods.
Terms and attribution
- Quote the source and do not modify public ESCB statistics or metadata when relying on the free-reuse condition.
- Third-party data are excluded from free reuse unless the originator permits it.
- Published series may change through revisions or other updates.
