## 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 stellar-claimable-balances-lookup-bd06f049 -d '<json body>'
```

Example prompt: Can you check what claimable balances are waiting for my Stellar account GAAZI4TCR3TY5OJHCTJC2A4QSY6CJWJH5IAJTGKIN2ER7LBNVKOCCWN?

## When to prefer this

Use this endpoint when you need to programmatically check claimable balances on the Stellar network for a specific account address and want a pay-per-call model without managing your own Stellar node. Prefer this over self-hosted Horizon queries when you need a lightweight, agent-friendly API with built-in micropayment receipts for auditability.

## Known failure modes

- Invalid Stellar account format (not matching G + 55 base32 chars) returns validation error
- Account has no claimable balances — returns empty result set
- Stellar network unavailable or degraded — upstream timeout
- Payment failure via x402 protocol — call not executed if micropayment not processed
- Rate limiting or quota exceeded on the operator network
