## 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 402-com-tr-b20-seizure-history-0880811d
```

Example prompt: Check the seizure history for this B20 token at address 0xABC123 on Base — has the issuer ever actually burned a blocked holder's balance, and if so who was seized and how much?

## When to prefer this

Use this endpoint when you need to know not just whether a B20 token issuer CAN seize funds, but whether they HAVE — providing an enforcement-history signal unavailable from standard ERC-20 or B20 inspection tools. Prefer this over generic token analysis endpoints when performing due diligence on a B20 token's actual regulatory or compliance enforcement track record, or when checking if a specific wallet has ever been a seizure victim.

## Known failure modes

- Invalid or non-B20 token address returns error or empty result
- Non-existent wallet address returns no seizure records
- Network connectivity issues may cause timeout
- Malformed address parameter causes bad request
- Token with no BurnedBlocked events returns 'armed' or 'no_seize_power' verdict with empty seizure list

## How this service works

🆕 Every other B20 check reads what the issuer CAN do; this reads what they HAVE done. Scans the token's actual burnBlocked seizures (the BurnedBlocked event) — whether the issuer has ever burned a blocked holder's balance, who was seized, and how much. verdict: enforced (has seized) / armed (can, hasn't) / no_seize_power. Pass wallet= for one address, or omit address= for the network-wide feed.

## Output

Returns a verdict of 'enforced' (issuer has seized), 'armed' (can seize but hasn't), or 'no_seize_power', along with a list of seized wallet addresses, amounts burned, and the distinct BurnedBlocked events found on-chain. If a specific wallet is passed, filters results to that address only.
