curl 'https://settla.net/api/v1/btc/block/hash/00000000000000000001595977e6000ce56129f5c9b4073e31ccc30b90b97da9/transactions/count' \
  -H 'X-API-Key: $SETTLA_API_KEY' \
  -H 'Accept: application/json'

Returns the number of transactions in a block identified by hash using getblock with verbosity 1. The cheap counterpart to /block/hash/{blockHash} — the node is asked for transaction ids only, not full bodies. An unknown hash answers 500 with the generic connection message.
