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
A JSON object containing the risk level (low/medium/high), a numeric risk score, verification status, a plain-English summary, and a list of findings each with a code, title, and severity — explicitly noting this is a heuristic screen, not an audit.
Example use cases
Pre-swap DeFi token safety check
“I'm about to swap into this token on Base — can you screen the contract at 0xAbCd1234...5678 and tell me if there are any honeypot signals, proxy risks, or owner privileges I should know about before I sign?”
NFT mint contract review
“I found an NFT mint contract at 0x9a8b...3c2d on Ethereum — can you do a safety check on it and give me a plain-English verdict on whether it looks legit or has any scary findings?”
Agent wallet protection before approval
“My agent is about to approve a contract interaction with 0xDEAD...BEEF on Base — run a contract screen first and flag anything with medium or high severity so I can decide whether to proceed.”
Technical details
Endpoint
GEThttps://mini-tollbooth.onrender.com/contract-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent or user needs a fast, pre-transaction heuristic safety screen on a specific smart contract address on Base or Ethereum — especially before approvals, swaps, or mints. It is purpose-built for agent-layer risk gating, returning structured findings and a plain-English verdict rather than raw on-chain data, making it ideal for automated decision pipelines that need interpretable risk signals without a full audit.
Side effects
- Invalid or non-existent contract address returns an error or empty findings
- Unsupported chain value returns a validation error
- Contract not yet indexed or very new may return incomplete data
- Payment of $0.10 USDC required per call — insufficient funds causes 402 rejection
- Rate limiting or service downtime on the hosted Render instance
