## 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 agent-trust-api-batch-wallet-trust-scoring-2044e61c
```

Example prompt: Can you run a trust check on these 5 Base wallets all at once and give me each one's score, grade, and any x402 flags: 0xABC…, 0xDEF…, 0x123…, 0x456…, 0x789…?

## When to prefer this

Use this endpoint when you need to evaluate multiple Base wallets simultaneously and want to minimize API call overhead and cost ($0.015/wallet in batch vs higher per-call cost on single-wallet endpoints). Ideal for agent workflows that need to screen a list of counterparties, participants, or transaction partners in one shot rather than making sequential single-wallet calls.

## Known failure modes

- More than 10 addresses submitted — API likely rejects or truncates beyond batch limit
- Invalid or malformed Ethereum address format — individual address may return error or null result
- Address not found on Base network — may return low default score or error
- Payment not fulfilled (x402) — returns 402 Payment Required before scoring begins
- Network timeout for large batch — partial results or timeout error

## How this service works

Batch trust scoring — score up to 10 Base wallets in one call. POST { addresses: ["0x..."] }. Returns score, grade, tier, x402 flags per wallet. Best value at $0.015 per wallet.

## Output

Returns an array of per-wallet results, each containing: numeric trust score (0-100), letter grade (A-F), trust tier classification, and x402 ecosystem flags indicating participation or risk signals in the x402 payment ecosystem.
