  description: |
    This API server is the layer that allows 3rd party apps and services interfacing with the coordinator to explore, monitor and use the Hermez rollup.
    Example of these apps are:
    * Wallet: send L2 transactions, check balance, ...
    * Explorer: List transactions, slots, batches, ...
    * Exchange integrations
    
    ### Pagination
    
    #### Usage

    All the endpoints that return a list of undefined size use pagination. Unless the opposite is explicitly said.
    In order to use pagination, three query parameters are used:
    * `fromItem`: indicates the first item to be returned. In general, this parameter shouldn't be provided in the first call to the endpoint, and use the `itemId` of the last returned item (+/-) 1, if the order is (ascending/descending).
    * `order`: all pginated items are ordered chronologicaly. However the specific fields to guarantee this order depend on each endpoint. For this purpose, `itemId` is used (itemId follows ascending chronological order except for unforged L1 user transactions). If the parameter is not provided, ascending order will be used by default. 
    * `limit`: maximum amount of items to include in each response. Default is 20, maximum 2049.
    
    Responses for those endpoint will always include a `pagination` object. This object includes the total amount of items that the endpoint will return at a given time with the given filters. Apart from that, it also includes the `itemId` of the last and first items that will be returned (not in a single response but within the total items). These two properties can be used to know when to stop querying. 

    #### Reorgs and safetyness

    Since all the items are ordered chronologicaly, there are no safety problems when fetching items in ascending order, except for reorgs (more on this later).
    On the other hand, when iterating in descending order, new items will be added at the beginning. This doesn't cause any safety problem, but to get those new items, it's necessary to start queryng without the `fromItem` set to `pagination.lastItem`.
    To handle reorgs, the `itemId` can be used since it will change. This is important since other identifiers may be the same but with different content. As an example, if the batch 424 get's reorged, it will be deleted, but eventualy, a new batch 424 will appear with potentialy different content.

    ### Signatures

    The POST endpoint require to be signed using BabyJubJub or Ethereum keys. TODO: add references to libraries / examples / ...
