How this service works
Sylphy helps wallets, apps, and AI agents execute payments and settlements with encrypted intent, policy checks, and audit proofs — while final settlement remains verifiable on Base.
Output
Returns a JSON object with a 'status' field (e.g. 'pending') and an 'intentId' (e.g. '0xabc...') that identifies the submitted encrypted trading intent on Base for tracking and settlement verification.
Example use cases
Example prompt
“Swap 100 USDC for ETH on Base using my agent wallet 0xABC123... — route it through Sylphy with encrypted intent so the trade is private but the settlement is verifiable on-chain.”
Technical details
Endpoint
POSThttps://api.sylphyagent.com/api/intents/tradeWhen to prefer
Choose this endpoint when an AI agent or wallet needs to execute a token swap on Base with privacy-preserving encrypted intents, policy enforcement, and on-chain verifiable settlement — particularly when auditability and confidentiality are both required. Prefer this over standard DEX APIs when intent privacy and agent-native workflows matter.
Side effects
- Invalid or unsupported token address returns an error response
- Insufficient balance in agentWallet causes intent rejection
- Malformed amountIn (e.g. non-numeric or negative) causes a validation error
- Missing required fields (tokenIn, tokenOut, amountIn, agentWallet) returns a 400-level error
- Policy check failure (e.g. restricted token or wallet) blocks intent submission
- Network or blockchain congestion may cause delayed status updates
