## 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 x402-services-escrow-agreement-list-42a1b10f -d '<json body>'
```

## When to prefer this

Use this endpoint when you need to enumerate existing escrow/conditional-payment agreements by creator token or participant wallet address on this x402-based service. Prefer this over blockchain explorers when you need structured, pre-parsed agreement data without writing custom chain queries.

## Known failure modes

- Missing both token and party — returns error requiring at least one identifier
- Invalid 0x address format for party — returns validation error
- Unrecognized or unauthorized token — returns empty list or auth error
- Limit parameter out of range — may return default or error
- Service unavailable — 5xx response

## How this service works

List conditional-payment agreements for your token (yours) or a party address (involving that address). Send { token } or { party }.

## Output

A list of conditional-payment escrow agreements associated with the provided token or party address, including counterparty addresses, agreement details, and payment conditions, limited to the requested number of results.
