## 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 tracefast-ethereum-address-blacklist-events-b92450fd
```

Example prompt: Pull the latest blacklist events for Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — show me any add, remove, or enforce actions from all issuer contracts, most recent first.

## When to prefer this

Use this endpoint when you need a complete historical audit trail of blacklist events for a specific Ethereum address, including which issuer contracts have listed, delisted, or taken enforcement action, and you need results filtered by action type or issuer. Prefer this over a simple current-status check when you need the full event history, timestamps, or weight context of each issuer.

## Known failure modes

- Invalid or malformed address (not 0x-prefixed or wrong length) returns a 400 error
- Unknown or unsupported chain returns an error (endpoint is Ethereum mainnet only, chain ID 1)
- Address with no blacklist history returns an empty events array
- Invalid action filter value returns a validation error
- Expired or invalid cursor returns a pagination error
- Payment not provided or insufficient USDC results in 402 Payment Required

## How this service works

TraceFast live Ethereum data: every blacklist event any issuer contract recorded about the address — listed (`add`), unlisted (`remove`) or enforced against (`enforce`: funds destroyed or frozen) — newest first, with the issuer and its weight. Path address: The address, `0x`-prefixed, any case. Query: limit, cursor, issuerContract, action (see docs). Docs: https://docs.tracefast.xyz/api/risk-blacklist-events.md

## Output

A paginated list of blacklist events for the queried Ethereum address, ordered newest first. Each event includes the action type (add, remove, or enforce), the issuer contract that recorded the event, the issuer's weight/authority score, and event metadata such as block timestamp. A cursor is provided for fetching subsequent pages.
