Web service interface: Data

All the data stored in the Bundesbank time series database can be retrieved using the query string described below.

Description: The endpoint returns time series from the specified dataflow (e.g. BBEX3) with the specified key (e.g. A.AED.DEM.CA.AA.A04).

Parameters

Name

Description

Example

flowRef

DSI (Data Set Identifier), a reference to the dataflow.

BBEX3

BBK01

key

Request of the data of a time series key.

The combination of dimensions allows statistical data to be uniquely identified. This type of combination is known as a time series key.

Exception: The time series key for BBK01 consists of exactly one dimension.

The use of wildcards is supported.

SDMX time series key: D.USD.EUR.BB.AC.000

BBK01-time series key:

ST0304

Use of wildcards specifically for SDMX time series keys

Wildcarding is supported by omitting the value for the dimension to be wildcarded.

For example, the following time series key can be used to retrieve the data for all daily currencies against the euro: D..EUR.BB.AC.000

It should also be possible to set several wildcards in a single request.

Use of wildcards specifically for BBK01

The time series key for BBK01 consists of exactly one dimension.

The wildcard character “*” is intended to represent 0-N arbitrary characters. Wildcards can be placed anywhere within a word (even at the beginning).

It is possible to enter more than one wildcard character (*).

However, the dimension must contain at least one character that is not a wildcard.

Example: W* (all time series starting with “W” are found).

Query parameters

Parameters can be used to further specify or restrict the response of the web service.

All parameters are optional.

Query parameters	Description
startPeriod endPeriod	By entering a range of dates using the parameter “startPeriod”/“endPeriod”, the time period for the observations can be narrowed down further. The supported formats are: YYYY for annual data (e.g. 2019). Example: https://api.statistiken.bundesbank.de/rest/data/BBBZ1/A.ZV00.INET.A00.A12.000.IN.DE.N?startPeriod=2012&endPeriod=2016 YYYY-S[1-2] for semi-annual data (e.g. 2019-S1). Example: https://api.statistiken.bundesbank.de/rest/data/BBDB2/H.DE.Y.A.C.IFRS.B.A.K.E.E001.VGH.A?startPeriod=2017-S1&endPeriod=2019-S1 YYYY-Q [1-4] for quarterly data (e.g. 2019-Q1). Example: https://api.statistiken.bundesbank.de/rest/data/BBEE1/Q.DE.AAA.XY0AAA.R.AADTB.M00?startPeriod=2019-Q4&endPeriod=2020-Q2 YYYY-MM for monthly data (e.g. 2019-01). Example: https://api.statistiken.bundesbank.de/rest/data/BBDE1/M.DE.Y.BAA1.A2P000000.G.C.I15.A?startPeriod=2018-06&endPeriod=2020-06 YYYY-W[01-53] for weekly data (e.g. 2019-W01). Example: https://api.statistiken.bundesbank.de/rest/data/BBQFS/W.DE.0000.WAI_UNCSHOCK._X.0000?startPeriod=2019-W01 YYYY-MM-DD for daily data and business data (e.g. 2019-01-01). Example: https://api.statistiken.bundesbank.de/rest/data/BBEX3/D.USD.EUR.BB.AC.000?startPeriod=2020-11-05&endPeriod=2020-11-10
detail	The “detail” parameter allows you to select how much information you wish the web service to return. Possible options are: full: All data values and attributes are returned. This is the default setting. Example: https://api.statistiken.bundesbank.de/rest/data/BBEX3/D.USD.EUR.BB.AC.000?detail=full dataonly: Only data values are returned, not attributes. Example: https://api.statistiken.bundesbank.de/rest/data/BBEX3/D.USD.EUR.BB.AC.000?detail=dataonly serieskeyonly: Time series keys, excluding attributes and data values. Example: https://api.statistiken.bundesbank.de/rest/data/BBEX3/D.USD.EUR.BB.AC.000?detail=serieskeyonly nodata: Time series keys, including attributes, but excluding data values. Example: https://api.statistiken.bundesbank.de/rest/data/BBEX3/D.USD.EUR.BB.AC.000?detail=nodata
firstNObservations	The “firstNObservations” parameter allows you to specify the maximum number of observations to be returned for each requested time series, starting with the first observation. Example: https://api.statistiken.bundesbank.de/rest/data/BBEX3/D.USD.EUR.BB.AC.000?detail=full&firstNObservations=27
lastNObservations	The “lastNObservations” parameter allows you to specify the maximum number of observations to be returned for each requested time series, in descending order from the last observation. Example: https://api.statistiken.bundesbank.de/rest/data/BBEX3/D.USD.EUR.BB.AC.000?detail=full&lastNObservations=12

Combining parameters

The following table shows which parameter combinations are permitted:

startPeriod – endPeriod – firstNObservations – lastNObservations

Return format

Return type

Description

data+csv and
data+csv-zip

With the return type “data + csv” a maximum of 200 time series of a frequency can be called up, otherwise an error message follows.

If more than 200 time series or time series with different frequency are to be called up in CSV format, the return type “data + csv-zip” must be selected. Exactly one ZIP file is then returned, the content of which consists of several CSV files. If time series of different frequencies were requested by a query, the time series for each frequency are written in several CSVs, which are returned in the ZIP.

With different frequencies there is a separate sequence number for each frequency.

Filename-ZIP: flowRef. (Key or WildcardingKey)_CSV.ZIP

Example: BBDE1.M ... ACP_CSV.ZIP

CSV file names: flowRef.Frequency (consecutive number) .csv

Example:

BBDE1.M(01).csv
BBDE1.M(02).csv
BBDE1.A(01).csv
BBDE1.Q(01).csv
BBDE1.Q(02).csv
BBDE1.Q(03).csv

genericdata+xml

With the return type “genericdata + xml”, time series with different frequencies can be called up.
