BlockCypher MicroTX transaction fee? does anyone know how much is the BlockCypher fee when doing Micro TX? I read here (https://www.blockcypher.com/dev/bitcoin/#microtx) and it says it is generated automatically (deducted from source). I need specifics, like is it in % or a fixed value,  but cannot find any.
The Microtransaction API documentation it describes a BlockCypher MicroTX as a normal transaction. BlockCypher just checks that the transaction has reached 98% on their confidence-factor and is therefore included in the next block.

However the documentation (and the whole concept) seems to be outdated.


  The Microtransaction API will accept values between 7,000 satoshis (~$0.04) and 4,000,000 satoshis (~$20). Anything below or above these thresholds will return an error.


At the time of writing (BTC @ ~$7000) the 7000 satoshi would be worth ~$0.49. In the Microtransaction API they alert that MircoTX are not feasible anymore and the API is therefore discontinued on bitcoin.


  Due to congestion on the Bitcoin network and the drastic increase in miner fees, microtransactions have become uneconomical. As a result, our microtransaction API isn’t supported on bitcoin anymore.
