- Include token in
Authorization: Bearer <token>header
Path Parameters
Query Parameters
When true, the server blocks up to 60 seconds waiting
for the session to transition to a terminal state
(completed, failed, expired). Useful to avoid
tight-loop polling.
Response
Payment session state
Available options:
pending, completed, failed, expired Amount as string to avoid float precision
Example:
"USDC"
Example:
"base-sepolia"
Wallet address to pay
Human-facing payment URL
Payer wallet address, set on completion.
On-chain transaction hash (when status = completed).
