Choose this endpoint when you need to self-serve list a new asset or token on the Blockle non-custodial atomic-swap exchange, add extra trading pairs, or settle a priced action on the Blockle platform — specifically when the listing fee payment via x402/USDC is acceptable and non-custodial atomic-swap mechanics are desired over a custodial CEX listing.
