How this service works
Convert natural language intent to swap transaction
Output
Returns an executable swap transaction payload derived from the natural language swap intent, including token pair, amounts, and transaction data ready for signing and broadcasting.
Example use cases
Convert spoken trade to transaction
“I just told my assistant 'swap 50 USDC for DAI from my wallet 0x1234...abcd' — can you turn that into an actual transaction I can sign and broadcast?”
DeFi swap from plain English
“Build me a ready-to-sign swap transaction from this: 'exchange 2 ETH for as much WBTC as possible using wallet 0xDEAD...BEEF'.”
Automate portfolio rebalancing swap
“I want to rebalance my portfolio — take my description 'swap 500 USDC for ETH' and generate the blockchain transaction I need to execute it on-chain.”
Technical details
Endpoint
POSThttps://api.w3-ipfs.xyz/x402/intent-to-swap-txWhen to prefer
Use this endpoint when you need to bridge the gap between a user's plain-English swap request and an actual on-chain swap transaction, especially in AI agent workflows where the user describes their trade intent conversationally rather than specifying raw transaction parameters.
Side effects
- Ambiguous intent with unclear token names or amounts returns a parsing error
- Unsupported token pair returns an error indicating the swap cannot be constructed
- Missing wallet address or recipient details may cause transaction generation to fail
- Malformed or nonsensical natural language input returns a bad request error
- Network or service unavailability returns a 5xx error
