## 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 synapse-api-zora-transaction-history-77ef4cb8 -d '<json body>'
```

Example prompt: Show me the last 25 transactions involving the Zora wallet 0xABC...123, sorted newest first, including metadata and excluding zero-value transfers.

## When to prefer this

Use this endpoint when you need on-chain transaction history specifically on the Zora network and want flexible filtering by address, block range, category, and sort order. Prefer this over generic blockchain explorers when you need programmatic, paginated access to Zora transaction data with optional metadata enrichment at low per-call cost.

## Known failure modes

- Invalid or malformed address returns an error or empty result set
- Invalid block range (fromBlock > toBlock) may return an error
- Invalid pageKey returns an error or resets pagination
- Unsupported category values may be silently ignored or cause an error
- Rate limiting or payment failure results in a 402 or 429 response
- No transactions found in the given range returns an empty array
