x402
M2M Sentinel — Base Contract Bytecode & Proxy Audit is a paid API for AI agents from api.m2msentinel.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).
Returns static bytecode capability analysis and proxy pattern observations for a given Base mainnet contract address

How this service works
Before you sign: can this Base contract be paused, frozen, or have tokens minted by its owner, self-destruct, or delegate execution somewhere you have not seen? Returns the opcodes and selectors actually present in the deployed bytecode, resolves proxies and EIP-7702 delegated accounts to what really runs, and states the trust level behind the answer. Evidence for your policy, not a safety verdict.
Output
A JSON object with a 'status' field (SUCCESS) and an 'audit' object containing static bytecode capability findings and proxy pattern observations for the queried Base mainnet contract address.
Example use cases
DeFi protocol upgrade risk check
“Before I interact with this Base DeFi protocol, can you check whether the contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 is upgradeable or uses a proxy pattern? I want to know the upgrade risk.”
New token contract due diligence
“I'm considering investing in a token on Base — can you audit the contract at 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb and tell me what capabilities its bytecode has and whether there's any proxy or admin backdoor?”
On-chain integration sanity check
“We're about to integrate with a Base contract at 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA — can you run a static bytecode audit on it so I can see if it delegates calls or has any unusual proxy structure before we go live?”
Technical details
Endpoint
GEThttps://api.m2msentinel.com/v1/audit/:address?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need static bytecode-level analysis and proxy pattern detection for a specific Base mainnet contract, especially for due diligence on DeFi protocols, token contracts, or any on-chain integration. It complements runtime/live data endpoints (price, liquidity, large transfers) by providing structural contract intelligence. Prefer it over general block explorers when you need structured, machine-readable audit output rather than raw bytecode or human-readable explorer pages.
Side effects
- Invalid or malformed address (not a valid 0x hex address) — likely 4xx validation error
- Address is an EOA (externally owned account) rather than a contract — audit may return empty or limited results
- Contract not indexed or not tracked by M2M Sentinel — may return empty audit object
- Network or provider downtime — service unavailable error
- Payment failure via x402 protocol — request rejected before reaching the API
