Use the tariffs endpoint to retrieve the raw tariffs that were shared with Eco-Movement by the CPOs using the OCPI protocol.



The tariffs endpoint is still active, but the prices endpoint is much more complete and is contributed by multiple sources.

The tariffs endpoint provides a list of prices at the connector level. In locations endpoint's result, the tariffs_id attribute corresponds with the tariffs endpoint.



Eco-Movement recommends that you retrieve all the tariffs once a day or once a week.


The request for the tariffs endpoint contains a few query parameters.

See tariffs to know more about the parameters that are used with the tariffs endpoint.


The following is a sample response for the tariffs endpoint:

    data: [  
        element 1 
        element 2 



Eco-Movement always upholds the API contract, but we may send new attributes in our JSON response when:

  • we add an OCPI mandatory attribute to the JSON response to be OCPI compliant
  • we improve your licensing module with new features

Hence, we strongly recommend that you handle or ignore unknown JSON fields.

Response Definitions

The following are the attributes for the tariffs endpoint:

data.idThe unique id for a tariff.
data.currencyThe three digit currency code of the country where the charging station is located.
data.tariff_alt_textA list of multi language alternative tariff information text.
data.tariff_alt_urlThe alternative URL for tariff information.
data.last_updatedThe timestamp when the Tariff was last updated or
data.cpo_tariff_idThe unique ID of the tariff in the system of the CPO.
data.elementsThe list of tariff elements.
data.elements.price_componentsThe list of price components that make up the
pricing of the tariff.
data.elements.price_components.typeThe type of tariff. The different types of tariff are:

- ENERGY: The price per kWh.

- FLAT: The fixed price per charging session.

- PARKING_TIME: The parking price per hour.

- TIME: The fixed price per hour.
data.elements.price_components.priceThe price per unit for the tariff type.
data.elements.price_components.step_sizeIndicates the minimum amount that is billed. A
unit is billed in step_size blocks. For example, if the type is TIME and step_size is 300, then the time is billed in blocks of 5 minutes. Hence, if 6 minutes is used, then 10 minutes (2 blocks of step_size) is billed.

Note: step_size also depends on the type. Every type (except FLAT) defines a step_size multiplier. This is the size of every 'step' and the unit. For example, PARKING_TIME has a step_size multiplier of 1 second. Therefore, step_size of a price component is multiplied by 1 second. Thus, step_size = 300 means 300 seconds.
data.elements.price_components.restrictionsThe list of restrictions for the tariff. The restrictions are:

- start_time: The starting time of the day for the tariff.

- end_time: The ending time of the day for the tariff.

- start_date: The starting date for the tariff.

- end_date: The ending date for the tariff.

- min_kwh: The minimum energy used in kWh.

- max_kwh: The maximum energy used in kWh.

- min_power: The minimum charging speed in kW.

- max_power: The maximum charging speed in kW.

- min_duration: The minimum duration in seconds.

- max_duration: The maximum duration in seconds.

- day_of_week: The day(s) of the week that the tariff is valid.
