operationId: get_contract_data_map_entry
description: |
Attempt to fetch data from a contract data map. The contract is identified with [Stacks Address] and [Contract Name] in the URL path. The map is identified with [Map Name].
The key to lookup in the map is supplied via the POST body. This should be supplied as the hex string serialization of the key (which should be a Clarity value). Note, this is a JSON string atom.
In the response, `data` is the hex serialization of the map response. Note that map responses are Clarity option types, for non-existent values, this is a serialized none, and for all other responses, it is a serialized (some ...) object.

/v2/fees/transaction:
post:
summary: Get approximate fees for the given transaction
tags:
- Fees
description: |
Get an estimated fee for the supplied transaction. This
estimates the execution cost of the transaction, the current
fee rate of the network, and returns estimates for fee
amounts.
* `transaction_payload` is a hex-encoded serialization of
the TransactionPayload for the transaction.
* `estimated_len` is an optional argument that provides the
endpoint with an estimation of the final length (in bytes)
of the transaction, including any post-conditions and
signatures
If the node cannot provide an estimate for the transaction
(e.g., if the node has never seen a contract-call for the
given contract and function) or if estimation is not
configured on this node, a 400 response is returned.
The 400 response will be a JSON error containing a `reason`
field which can be one of the following:
* `DatabaseError` - this Stacks node has had an internal
database error while trying to estimate the costs of the
supplied transaction.
* `NoEstimateAvailable` - this Stacks node has not seen this
kind of contract-call before, and it cannot provide an
estimate yet.
* `CostEstimationDisabled` - this Stacks node does not perform
fee or cost estimation, and it cannot respond on this
endpoint.
The 200 response contains the following data:
* `estimated_cost` - the estimated multi-dimensional cost of
executing the Clarity VM on the provided transaction.
* `estimated_cost_scalar` - a unitless integer that captures
the total proportion of the block limit that a transaction
would be estimated to consume. In order to compute an
estimate of total fee amount for the transaction, this value
is multiplied by the estimated fee rate. This value
incorporates the estimated transaction length.
* `cost_scalar_change_by_byte` - a float value that indicates how
much the `estimated_cost_scalar` value would increase for every
additional byte in the final transaction.
* `estimations` - an array of estimated fee rates and total fees to
pay in microSTX for the transaction. This array provides a range of
estimates (default: 3) that may be used. Each element of the array
contains the following fields:
* `fee_rate` - the estimated value for the current fee
rates in the network
* `fee` - the estimated value for the total fee in
microSTX that the given transaction should pay. These
values are the result of computing:
`fee_rate` x `estimated_cost_scalar`.
If the estimated fees are less than the minimum relay
fee `(1 ustx x estimated_len)`, then that minimum relay
fee will be returned here instead.
Note: If the final transaction's byte size is larger than
supplied to `estimated_len`, then applications should increase
this fee amount by:
`fee_rate` x `cost_scalar_change_by_byte` x (`final_size` - `estimated_size`)
