## 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 x402-chain-intel-wallet-approvals-8c76aa56 -d '<json body>'
```

Example prompt: Pull all token approvals currently granted by wallet 0xABC...123 on Ethereum mainnet so I can audit which spenders still have unlimited allowances.

## When to prefer this

Use this endpoint when a trading bot or DeFi agent needs to programmatically inspect on-chain token approval state for a specific wallet — particularly to audit allowance exposure, verify pre-trade permissions, or flag unlimited approvals as a security check. Prefer this over general blockchain explorers when you need structured, machine-readable approval data ready for automated consumption.

## Known failure modes

- Invalid or malformed wallet address returns a 400 error
- Unsupported blockchain network returns an error or empty result
- Rate limiting or payment failure via x402 returns a 402 response requiring USDC payment
- Wallet with no approvals returns an empty list
- RPC node downtime may cause timeouts or incomplete data
