Example prompt: Grant consent on the Vaultfire ERC-8004 Identity Registry for purpose hash 0xabc123...def for my agent wallet 0x742d35Cc6634C0532925a3b8D4C9E4f5e6b1234 — I'll sign the returned transaction in my wallet.

## When to prefer this

Use this endpoint when an AI agent needs to record a privacy-preserving, on-chain consent decision tied to a specific purpose hash against its ERC-8004 identity. Prefer this over off-chain consent mechanisms when auditability, decentralization, and agent accountability on Base mainnet are required.

## Known failure modes

- Invalid or malformed purpose hash returns a 400 error
- Insufficient USDC balance or failed x402 payment returns a 402 Payment Required error
- Agent wallet not registered on ERC-8004 registry returns a 404 or 422 error
- Unsupported chain or contract not found returns a 400 or 500 error
- Consent already granted for this purpose hash may return a conflict or no-op response

## How this service works

Grant consent for a specific purpose hash on the ERC-8004 Identity Registry. Pay $0.05 USDC, sign in your wallet — privacy-preserving consent flagging tied to your agent identity.

## Output

An unsigned transaction object that the calling agent or user must sign with their wallet to record the consent flag for the specified purpose hash on the ERC-8004 Identity Registry on-chain. Includes transaction data, target contract address, and relevant metadata for the consent operation.
