How this service works
Paid: /v1/verify, /v1/risk, /v1/receipt cost $0.01 USDC per call on Base mainnet via x402 (payTo 0x719227f384b66BFEF00093D6d8d32fA9dC2B40e7); utilities analyze Base mainnet (USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) by default, network=base-sepolia optional; /v1/receipt/verify and discovery files are free. Operator: Beggar Bot.
Output
Returns a JSON object containing the current Permit2 nonce value for the requested wallet address on the specified network (Base mainnet by default, or Base Sepolia if network=base-sepolia is provided). The nonce is needed to construct valid Permit2 signatures for token approvals and transfers.
Example use cases
Pre-signing permit nonce check
“Before I sign a Permit2 transfer for my wallet 0x1234...abcd on Base mainnet, can you look up the current Permit2 nonce so I don't reuse an old one?”
DeFi bot nonce validation
“My trading bot needs the latest Permit2 nonce for address 0xDeFi...5678 on Base mainnet before constructing the next signed approval — can you fetch it?”
Sepolia testnet nonce lookup
“I'm testing a permit2 flow on Base Sepolia — what's the current permit2 nonce for wallet 0xTest...9999 on base-sepolia?”
Technical details
Endpoint
GEThttps://beggar-bot-demand.beggarbot.workers.dev/v1/permit2nonce?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the current Permit2 nonce for a specific wallet address on Base mainnet (or Base Sepolia) before constructing a Permit2-based signed token approval or transfer. Prefer this over building your own RPC call when you want a simple REST interface to Permit2 nonce data without managing raw Ethereum JSON-RPC infrastructure. It is paid ($0.02 USDC via x402) and targets Base/Base Sepolia specifically.
Side effects
- Invalid or missing wallet address parameter returns an error response
- Network not supported returns a configuration error
- Upstream Base RPC unavailable causes a timeout or 5xx error
- Malformed request (wrong property types) may return a 400 or JSON error
- Rate limiting or payment failure via x402 may block the call
