Example prompt: I want to revoke my previously granted consent for purpose hash 0xabc123...def456 on the Vaultfire ERC-8004 Identity Registry — prepare the unsigned transaction so I can sign it with my wallet.

## When to prefer this

Use this endpoint when you need to revoke a specific, previously-granted on-chain consent record tied to a purpose hash on the ERC-8004 Identity Registry within the Vaultfire Protocol ecosystem. Prefer this over generic blockchain write tools when dealing specifically with ERC-8004 consent lifecycle management on Base mainnet with x402 micropayment authentication.

## Known failure modes

- Invalid or unrecognized purpose hash — returns 400 with error detail
- Consent not previously granted for the given purpose hash — registry lookup fails
- Payment of $0.05 USDC not provided or invalid x402 header — returns 402 Payment Required
- Wallet address not registered on ERC-8004 Identity Registry — returns 404
- On-chain registry unavailable or RPC node error — returns 503

## How this service works

Revoke previously-granted consent for a specific purpose hash on the ERC-8004 Identity Registry. Pay $0.05 USDC, sign in your wallet — completes the privacy-preserving consent loop.

## Output

An unsigned transaction payload that, once signed and broadcast, revokes the specified purpose hash consent on the ERC-8004 Identity Registry. Includes transaction data targeting the Vaultfire smart contract on Base mainnet, confirming the consent withdrawal.
