# signals.edge.report Nonce Lookup

> signals.edge.report Nonce Lookup is a paid API for AI agents from signals.edge.report, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Returns the current transaction nonce (eth_getTransactionCount) for an EVM wallet address on Base or Ethereum, essential for constructing valid transactions.

## Facts

- Endpoint: GET https://signals.edge.report/v1/nonce
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/signals-edge-report-nonce-lookup-fa561c5c
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_3kfqu6tkXHK_Qiw32AOcs

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 signals-edge-report-nonce-lookup-fa561c5c
```

Example prompt: Before I send my next transaction, can you check the current nonce for wallet 0xAbC123...456 on Base so I know what value to use?

## When to prefer this

Use this endpoint when an AI agent needs to construct or broadcast a raw EVM transaction on Base or Ethereum and must know the correct nonce to include. Prefer this over general RPC calls when you want a simple, paid, pre-configured REST interface rather than setting up your own JSON-RPC connection. It is especially convenient alongside the sibling gas fee and wallet balance endpoints from signals.edge.report for a complete pre-transaction data bundle.

## Known failure modes

- Invalid or malformed EVM wallet address returns an error
- Unsupported chain value (anything other than 'base' or 'ethereum') may return an error or default to Base
- Network connectivity issues to Base/Ethereum RPC may cause timeouts
- Rate limiting if called excessively without payment

## How this service works

Get the current transaction nonce for an EVM wallet on Base (or Ethereum) via eth_getTransactionCount. Use before broadcasting a transaction.

## Output

Returns the current transaction count (nonce) for the specified EVM wallet address, representing how many confirmed transactions the wallet has sent. This value is used directly as the nonce field when constructing a new transaction on Base or Ethereum.
