## 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 ragradar-token-approvals-lookup-27425357
```

Example prompt: Check all token approvals for wallet address 0xABC123...DEF on Base — I want to see which contracts or protocols have been granted spending permissions.

## When to prefer this

Use this endpoint when you need to audit or inspect token spending approvals granted by a specific wallet address on Base, Arbitrum, or Solana. Prefer this over generic block explorers when you need structured, machine-readable approval data accessible via micropayment for AI agent workflows.

## Known failure modes

- Invalid or unsupported chain identifier returns an error
- Malformed wallet address returns a validation error
- No approvals found returns empty result set
- Payment not fulfilled via x402 returns 402 Payment Required
- Rate limiting or service unavailability returns 5xx error
