## 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 beggar-bot-eas-attestation-lookup-base-mainnet-4e6e2a96
```

Example prompt: Can you look up the EAS attestation on Base mainnet for wallet address 0xABC123...? I need to see what attestations are on record for it.

## When to prefer this

Use this endpoint when you need to retrieve EAS attestation records specifically on Base mainnet and are willing to pay $0.02 USDC per call via the x402 protocol. Prefer this over general blockchain explorers when you need structured JSON attestation data suitable for agent consumption, or when integrating into automated workflows that require on-chain identity or credential verification on Base.

## Known failure modes

- No attestation found for the given address or UID — returns empty or null result
- Invalid or malformed address/properties parameter — returns 400 error
- Payment not received or insufficient USDC — returns 402 Payment Required
- Rate limiting or Cloudflare Worker timeout — returns 429 or 503
- Queried entity does not exist on Base mainnet EAS — returns empty attestation set
