## 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 aegis-trust-batch-lookup-b6b42c2b -d '<json body>'
```

Example prompt: Before my agent pays any of these x402 services, batch-check their trust scores in Aegis so I know which ones are verified by real purchase history — use nonce 'batch-check-001' for idempotency.

## When to prefer this

Choose this endpoint when you need to verify the trustworthiness of multiple x402 agent-payable services in a single call rather than checking them one by one. It is ideal for agent orchestration layers that must pre-screen a batch of services before routing micropayments, or for periodic audits of a known service list. Prefer it over single-lookup endpoints when latency and cost efficiency matter across multiple targets.

## Known failure modes

- Empty or malformed request body returns validation error
- Unknown or unregistered service identifiers may return null trust scores or 404-equivalent entries
- Rate limiting or payment failure (insufficient USDC) blocks the call
- Response schema is undocumented so output structure may vary
- Nonce collisions may cause idempotent deduplication of repeated calls
