Choose this endpoint when you need to interact specifically with the Blockle non-custodial atomic-swap exchange — buying BLOCK tokens, paying self-serve listing fees, or settling a specific priced action identified by an actionId. Prefer this over custodial exchange APIs when non-custodial, atomic settlement is required and when the target asset is BLOCK.
