## 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-revoke-build-utility-base-mainnet-de5ef1df
```

Example prompt: Can you build me the revocation transaction payload for my EAS attestation on Base mainnet — the properties are for attestation UID 0xabc123?

## When to prefer this

Use this endpoint when you need to programmatically construct an EAS attestation revocation transaction on Base mainnet (or Base Sepolia) without manually encoding the contract calldata. It is preferable when building agent workflows that automate credential lifecycle management and need a ready-to-sign revoke payload at low cost ($0.02 USDC per call).

## Known failure modes

- Invalid or missing attestation UID returns an error response
- Attestation not found on the specified network
- Insufficient USDC payment via x402 results in 402 Payment Required
- Malformed properties input causes a parsing error
- Network mismatch between supplied UID and requested network

## How this service works

Paid: /v1/verify, /v1/risk, /v1/receipt cost $0.01 USDC per call on Base mainnet via x402 (payTo 0x719227f384b66BFEF00093D6d8d32fA9dC2B40e7); utilities analyze Base mainnet (USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) by default, network=base-sepolia optional; /v1/receipt/verify and discovery files are free. Operator: Beggar Bot.

## Output

Returns a JSON object containing the constructed EAS revocation transaction data or calldata, including parameters needed to sign and submit the revocation to the Base mainnet EAS contract.
