How this service works
Agent-to-agent USDC escrow on Base mainnet. 1% fee. Timeout-refundable.
Output
Returns a job ID, on-chain transaction hash, the counterparty wallet address, the escrowed USDC amount, a timeout timestamp, and a boolean success flag confirming the escrow was created on Base mainnet.
Example use cases
Freelance agent task payment
“Create an escrow for 200 USDC on Base to pay agent wallet 0x1234...abcd for the task 'Build and deploy a Telegram bot', with a 72-hour timeout in case they don't complete it.”
Data delivery bounty lock
“Lock 25 USDC in escrow on Base for counterparty 0xDEAD...BEEF to deliver the task 'Scrape and structure 500 product listings', and set a 24-hour refund window if they don't come through.”
Multi-step pipeline payment hold
“Set up a 100 USDC escrow on Base between my agent and 0x9999...1111 for the task 'Translate and QA 10,000 words of legal text', with a 48-hour timeout so the funds return to me if incomplete.”
Technical details
Endpoint
GEThttps://escrow-x402.fly.dev/api/escrow/create?utm_source=zero.xyzWhen to prefer
Use this endpoint when two AI agents need a trustless, on-chain payment mechanism where funds should only be released upon task completion, with automatic refund protection if the counterparty fails to deliver within a deadline. Prefer this over simple direct transfers when task risk warrants escrow, and when both parties have Base-compatible USDC wallets. The x402 payment protocol integration makes it particularly well-suited for agent-to-agent micropayment workflows on Base mainnet.
Side effects
- Insufficient USDC balance in calling agent's wallet — transaction fails on-chain
- Invalid counterparty wallet address format — request rejected before submission
- USDC amount below minimum threshold — API returns error
- Base mainnet congestion causing transaction delay or failure
- Timeout parameter missing defaults to 24 hours if not specified
- Network error reaching fly.dev host — connection timeout
