How this service works
List recent JPYC Transfer events on one supported chain from roughly the last hour of blocks, optionally filtered by address — tx hash, from, to, amount, block. Without a cursor: newest first. With a cursor: only events after that position, oldest first, so each observed event is returned once within the scanned window. Use to confirm a recent JPYC payment or monitor wallet activity. Not for history beyond the window, sanctions screening, identity, or finality proof.
Output
A list of JPYC transfer events from approximately the last hour of blocks on the specified chain, ordered newest first. Each record includes the transaction hash, sender (from) address, recipient (to) address, transfer amount, and block number. Optionally filtered to transfers involving a specific wallet address as either sender or recipient.
Example use cases
Audit wallet JPYC payment activity
“Pull up the last 50 JPYC transfers on Polygon where 0xAbC1234567890abcdef1234567890abcdef123456 was either the sender or receiver — I need to review recent payment activity for that wallet.”
Monitor JPYC chain activity dashboard
“Fetch the latest JPYC transfer events on Avalanche — no address filter, just give me the 20 most recent transfers across the whole chain so I can see what's moving.”
Verify JPYC payment was received
“Check if address 0xDef9876543210fedcba9876543210fedcba987654 received any JPYC on Ethereum in the past hour — I'm waiting on a payment and want to confirm it went through.”
Technical details
Endpoint
GEThttps://open-pay.jp/api/paid/usdc/jpyc/transfersWhen to prefer
Use this endpoint when you need real-time, on-chain JPYC transfer event data for the past hour on a specific supported chain, especially when monitoring a specific address for incoming or outgoing JPYC payments. Prefer this over balance checks when you need transaction-level detail (tx hash, from/to, amount per transfer) rather than a summary balance. Best suited for payment verification, activity auditing, and live transfer monitoring workflows.
Side effects
- Missing required 'chain' query parameter returns an error
- Invalid chain value (not polygon, kaia, avalanche, or ethereum) returns a validation error
- Malformed address (not matching 0x + 40 hex chars) returns a pattern validation error
- Limit value outside 1-100 range may be rejected or clamped
- No transfers in the last hour on a quiet chain returns an empty list
- Payment failure (insufficient USDC balance) blocks the request via x402 protocol
