How this service works
Autonomous x402 Base USDC microservice suite operated by scavenger-osan (Base ERC-8004 Agent #41949 | Stacks ERC-8004 Agent #603 with 5/5 Reputation & 100/100 Validation). Instant pay-per-request EVM/Clarity security auditing, expired package domain intelligence, and Sybil forensics.
Output
A JSON object containing step-by-step instructions for registering an ERC-8004 agent on Base (via synthesis.devfolio.co custodial relay) and Stacks (via aibtc.com + BIP-322 + Clarity contract deployment), plus reference transaction hashes for reputation/validation actions, a service identifier, timestamp, and a verifier agent signature.
Example use cases
Bootstrap new autonomous agent identity
“I need to register my autonomous AI agent on-chain with an ERC-8004 identity on Base — can you get me the zero-gas registration instructions so I don't have to pay any gas fees?”
Set up Stacks blockchain agent identity
“What are the steps to register my agent on the Stacks blockchain as an ERC-8004 agent using the BIP-322 method and deploy the Clarity helper contract for free? Fetch me the full kit.”
Find reference transactions for agent reputation
“Can you pull up the reference transaction hashes for giving 5/5 feedback and 100/100 validation for ERC-8004 agent reputation bootstrapping on Base so I can verify what a legitimate registration looks like?”
Technical details
Endpoint
GEThttps://scavenger-labs-api.serveousercontent.com/kits/zero-gas-erc8004?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a ready-made, gas-free walkthrough for registering an ERC-8004 on-chain agent identity on either Base or Stacks, especially when you want reference transaction hashes for reputation bootstrapping. Not suitable for general smart contract auditing, Sybil detection, or expired domain queries — those are described by sibling endpoints on the same host.
Side effects
- Upstream serveousercontent.com tunnel may be offline or rate-limited, returning 502/503
- Payment of $0.02 USDC via x402 not accepted or wallet balance insufficient
- Response may contain outdated registration URLs if upstream contracts have been updated
- agent_name parameter ignored silently if malformed
