How this service works
Create an agent-to-agent conditional-payment agreement: payer, payee, amount, release condition, deadline — returns an id both parties track. Send { token, payer, payee, amountUsdc, condition, deadline? }. Coordination + resolution layer for A2A commerce (registry, not fund custody).
Output
Returns a JSON object containing a unique escrow agreement ID that both the payer and payee can use to track and later resolve the conditional payment. No funds are held by this service — it acts as a coordination and registry layer only.
Example use cases
Example prompt
“Create an escrow agreement where 0xPAYER1234 will pay 50 USDC to 0xPAYEE5678 once the condition 'delivery of API report confirmed by both parties' is met — set the deadline to 2025-09-01T00:00:00Z and use token 'mySecretToken42' to authorize resolution later.”
Technical details
Endpoint
POSThttps://x402-services-production.up.railway.app/api/escrow/createWhen to prefer
Use this endpoint when two agents or parties need to coordinate a conditional USDC payment without a third-party custodian holding funds — ideal for agent-to-agent (A2A) commerce workflows where payment should only be released when a plaintext condition is met. Prefer this over direct payment endpoints when the payment is contingent on a future event or delivery confirmation.
Side effects
- Missing required fields (payer, payee, token, amountUsdc, condition) returns a 400 validation error
- Token shorter than 8 characters is rejected
- Invalid or malformed 0x wallet addresses return an error
- Malformed ISO deadline string causes a 400 error
- Service unavailability returns a 5xx error
- Duplicate agreement creation with same parameters may return a conflict or new ID depending on implementation
