## 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 zerion-api-tx-subscription-wallets-lookup-c3ec49bf
```

Example prompt: Show me the wallets associated with my Zerion transaction subscription ID 'sub_abc123xyz'.

## When to prefer this

Use this endpoint when you need to programmatically retrieve wallet addresses associated with a specific Zerion transaction subscription, particularly in agent workflows that monitor multi-chain wallet activity or need to audit subscription membership. Prefer this over general wallet lookup endpoints when working within the context of a subscription-based monitoring setup.

## Known failure modes

- Invalid or missing subscription_id returns a 404 or error response
- Expired or unauthorized subscription returns a 401/403 authentication error
- Malformed subscription ID format may return a 400 bad request
- Payment failure via x402 protocol results in 402 Payment Required

## How this service works

Interpreted wallet data for more than 40 chains and Solana: portfolios, DeFi positions, PnL, transactions and NFTs. REST for apps, x402 pay-per-call for agents.

## Output

Returns a JSON object containing the subscription's associated wallet resources, each with a resource ID, resource type, and attributes. Also includes pagination/self links for navigating results.
