## 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 public-zapper-xyz-520c3cf6 -d '<json body>'

## When to prefer this

Use this endpoint when you need to retrieve raw on-chain transaction history for one or more Ethereum-compatible wallet addresses, particularly when you want Zapper's enriched and aggregated transaction data. Prefer this over general blockchain explorers when you need multiple wallets queried simultaneously or want DeFi-aware transaction context.

## Known failure modes

- Invalid or malformed 0x wallet address returns an error or empty result
- Missing required 'subjects' field causes request validation failure
- Empty subjects array returns no results
- Payment failure (x402 insufficient funds) blocks the request
- Network timeout or Zapper service unavailability returns a server error

## How this service works

Enterprise grade onchain data across 60+ chains - token prices, NFTs, portfolios, onchain search, Farcaster and more.

## Output

Returns a list of on-chain transactions associated with the submitted wallet address(es), including transaction details such as actions, timestamps, and token movements, as paginated results (default 10 per query).
