## 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-boba-network-transaction-history-b908c2b8 -d '<json body>'

Example prompt: Pull the last 25 transactions sent from wallet 0xAbCd...1234 on Boba Network, sorted newest first, and include token metadata.

## When to prefer this

Use this endpoint when you need on-chain transaction history specifically for the Boba Network blockchain. Prefer it over generic Ethereum history APIs when the user's activity is on Boba's L2, or when you need Boba-specific asset transfer filtering with block-range control and metadata enrichment.

## Known failure modes

- Invalid address format returns an error or empty result
- fromBlock/toBlock out of range returns empty list
- Invalid category values cause a 400 error
- Expired or invalid pageKey returns error or unexpected results
- Network timeouts on very large block ranges
