## 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-8e7b2e3a
```

Example prompt: Can you pull up all the token approvals for wallet 0xAbCd1234... on Base so I can see which contracts are allowed to spend my tokens?

## When to prefer this

Choose this endpoint when you need to audit or inspect on-chain token approvals (ERC-20 allowances or equivalent) for a specific wallet address on Base, Arbitrum, or Solana. It is particularly useful for security audits, DeFi risk management, or pre-revocation checks. Prefer this over generic blockchain explorers when you need structured, agent-consumable data with micropayment access via x402.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Unsupported chain identifier causes a bad request response
- Address with no approvals returns an empty approvals array
- Network congestion or RPC issues may cause timeouts
- Rate limiting if too many requests are made in quick succession

## How this service works

On-chain intelligence for AI agents. 70+ endpoints across Base, Arbitrum, Solana. x402 micropayments.

## Output
