## 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 blockscout-account-abstraction-bundlers-list-1bd639ec
```

Example prompt: Show me all the ERC-4337 account abstraction bundlers active on Ethereum mainnet — I want to see their addresses, names, and how many bundles and operations they've each handled.

## When to prefer this

Choose this endpoint when you need to discover and enumerate ERC-4337 account abstraction bundlers on a specific blockchain network supported by Blockscout, especially when you need rich address metadata (ENS, tags, reputation) alongside bundle and operation statistics. Prefer this over raw RPC calls when you want pre-enriched, human-readable bundler data with pagination support across multiple chains.

## Known failure modes

- Invalid or unsupported chain_id returns an error or empty result
- Invalid page_token causes pagination failure
- Rate limiting or payment failure returns 402
- Network or chain not indexed by Blockscout returns empty items array
- Malformed query parameters may return 400 Bad Request

## Output

A paginated JSON response containing an array of bundler objects, each with the bundler's address details (hash, name, scam flag, proxy type, reputation, contract status, verification status, ENS domain, public/private tags, watchlist names, and implementations), plus aggregate metrics (total_ops and total_bundles). Also includes next_page_params for pagination.
