How this service works
The insurance booth for AI agents, with Mini's Agent Supply Store on the side of the road. One hundred checkpoints: pre-transaction safety lanes (honeypot, approval-risk, rug-score, receipt-check, tx-dryrun, permit-scan, airdrop-verdict, deployer-history, wallet-watch, secret-scan at $0.02 USDC per call; the protection tier — /contract-check, /approval-screen, /tx-plain-english, /honeypot-check, /tx-simulate, /redteam, /skill-scan, /verdict, /egress-audit, /tool-gate, /airlock, /repo-scan, /prove, /task-scope — at $0.10; the one-call /shield don't-get-rugged screen at $0.25; the full /preflight bundle at $0.05), bounty intel (bounties, fresh, verdicts, deadlines, sweepstakes, opportunities) at $0.02 USDC per call, trader intel (/prices and /quant at $0.02; /enrich and /token-check at $0.05; /contract-check and /honeypot-check at $0.10; /sec-facts at $0.05), market intel (/markets and /search at $0.05; /grants at $0.02), DeFi intel (/yields and /new-pairs at $0.05; /gas and /defi at $0.02), AI intel (/models at $0.02), agent-ops intel (/prompt-cost, /model-picks, /rpc-speed, /terms-tldr, /scrape, /gigs, /retry-verify, /idempotency, /verify-independent at $0.02; /site-watch, /wallet-check, /code-run, /regulatory-pack, /sage, /cron-watch, /caveat-check, /tripwire, /escrow, /trust, /bridge-fees, /dao-votes, /dev-activity, /dex-arb, /dydx-perps, /funding-rates, /gas-predict, /hack-tracker, /long-short-ratio, /lp-yields, /mev-scan, /open-interest, /perp-basis, /polymarket-odds, /rwa-watch, /sentiment, /stablecoin-flows, /tokenomics, /top-movers, /whale-watch, and /yield-stable at $0.05; /approval-screen, /tx-plain-english, /tx-simulate, and /task-scope at $0.10; /scam-scan deep scan at $5.00 or 30-day subscription at $30.00), supply store (/road-pack combo meal at $0.05; curated datasets, the /audit-prep pre-audit review, and the /prove-state symbolic-execution run at $1.00; the /audit AI-agent audit at $25.00). Every lane answers before money moves — heuristic verdicts, not audits. Don't get rugged.
Output
Returns a JSON object with: lane identifier (/audit-prep), risk level string (e.g. 'medium'), chain, contract address, a WARNING that this is NOT_AN_AUDIT, an array of findings each with a code/title/severity, a verified boolean (whether source was found on Sourcify), a numeric risk_score (0-100), a human-readable description of the analysis, and an array of three adversarial swarm_prompts ('the_attacker', 'the_economist', 'the_pedant') to guide further model-based review.
Example use cases
Pre-audit screening for DeFi protocol
“Before we send this contract to a paid auditor, can you run a pre-audit scan on 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum and give me the risk score, any reentrancy or access control findings, and the attacker/economist/pedant prompts?”
Proxy upgrade risk check
“We're about to upgrade our upgradeable proxy contract at 0x4200000000000000000000000000000000000006 on Base — can you do an audit-prep scan and tell me if there are any proxy or initializer issues flagged, and what the overall risk level is?”
Centralization and owner risk review
“I need to quickly assess centralization risks in this new contract at 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA on Base — run the static battery and show me all findings with their severities plus the adversarial prompts for my team to use.”
Technical details
Endpoint
GEThttps://mini-tollbooth.onrender.com/audit-prep?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, deterministic static security analysis of an EVM smart contract before commissioning a full human audit, or when you want adversarial prompts to guide your own model-based review. It covers reentrancy, access control, tx.origin, delegatecall, selfdestruct, initializers, proxy/upgradeability, OpenZeppelin drift, and centralization risks in a single call. Prefer this over manual code review tools when you need a structured risk score and machine-readable findings for Base or Ethereum contracts. Do NOT use this as a replacement for a professional audit — it is explicitly designed to make audits faster and cheaper, not to substitute for one.
Side effects
- Invalid or malformed contract address (not a valid 0x EVM address) — likely returns an error or empty findings
- Unsupported chain value — only 'base' and 'ethereum' are accepted; other values may return an error
- Contract not deployed or unverified source — verified flag will be false, static analysis may be limited
- Payment not received or insufficient USDC — x402 payment gate will reject the request
- Contract too large or complex for static battery — may timeout or return partial results
- Network/RPC issues on the specified chain — may return a service error
