Example use cases
ERC-4337 UserOp trace debugging
“I submitted a smart account transaction and got a UserOperation hash — can you look up 0xdeadbeef... on Base mainnet and tell me what that userop contains?”
Verify bundled transaction inclusion
“Can you fetch the userop hash 0x123abc... from Base mainnet and confirm whether it was included in a bundle and what the call data looks like?”
Audit UserOp for compliance review
“I need to review the details of UserOperation hash 0xfeed5678... on Base mainnet for a compliance check — can you pull the full record for me?”
Technical details
Endpoint
GEThttps://beggar-bot-demand.beggarbot.workers.dev/v1/userophash?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve or audit a specific UserOperation hash on Base mainnet (ERC-4337 account abstraction), especially in agent workflows that process smart account transactions and need structured userop metadata. Prefer this over generic block explorers when you need machine-readable JSON output consumable by an AI agent via a micropayment API.
Side effects
- Invalid or malformed userop hash returns an error response
- Hash not found on Base mainnet (hash may belong to a different network)
- Payment not provided or invalid x402 payment header results in 402 Payment Required
- Network parameter mismatch (e.g. querying base-sepolia hash against mainnet)
- Cloudflare Worker timeout or upstream RPC failure
