Example use cases
Automated DeFi swap pipeline
“I want to swap USDC for ETH through my on-chain agent — go ahead and pay the required swap-token execution fee so the trade can go through.”
Agent-driven portfolio rebalancing
“My portfolio bot needs to rebalance by swapping WBTC for USDT — please pay the 0.001 USDC execution fee so the keyring agent can process the token-for-token swap.”
One-click token exchange in dApp
“The user just hit 'swap' in my dApp — pay the swap-token execution fee now so the on-chain swap transaction gets unlocked and processed immediately.”
Technical details
Endpoint
GEThttps://keyring-agent.blockchhub.link/api/swap-tokenWhen to prefer
Use this endpoint specifically when an AI agent or automated workflow needs to pay the execution fee for a token-for-token swap operation (not ERC-20 transfers, NFT transfers, or liquidity provision). Choose this over sibling endpoints when the intended on-chain action is a token swap rather than a native coin transfer, NFT transfer, or lending market supply.
Side effects
- Payment insufficient — fee not covered, status not returned as 'ok'
- x402 payment protocol failure — handshake or authorization rejected
- Endpoint unreachable — network or DNS issue with blockchhub.link domain
- Timeout — fee settlement takes too long and request expires
- Duplicate payment attempt — idempotency not guaranteed, may result in double charge
