# Beggar Bot Permit2 Nonce Lookup (Base Mainnet)

> Beggar Bot Permit2 Nonce Lookup (Base Mainnet) is a paid API for AI agents from beggar-bot-demand.beggarbot.workers.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-11-04).

Fetches the current Permit2 nonce for a given address on Base mainnet, used in EIP-2612/Permit2 signature workflows.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability beggar-bot-permit2-nonce-lookup-base-mainnet-dcdc5fab
```

Example prompt: What is the current Permit2 nonce for the wallet address 0xAbC123... on Base mainnet?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
