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: the contract address checked, the chain, a verdict (VERIFIED / PARTIAL / UNVERIFIED), a human-readable detail describing the verification level (full Sourcify match, partial match, or unverified), the timestamp when verification occurred, a warning reminding the caller that verification does not imply safety, and the lane identifier (/verified-contracts).
Example use cases
Pre-trade contract legitimacy check
“Before I interact with this DeFi protocol, can you check if the contract at 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D on Ethereum has its source code verified on Sourcify?”
Multi-chain deployment source audit
“I deployed a contract on Base at 0xAbCd1234...5678 — can you verify that the deployed bytecode matches the source code I published, using the Sourcify check on TrollBridge?”
Due diligence on unfamiliar token contract
“I'm looking at a new token on Arbitrum at 0x912CE59144191C1204E64559FE8253a0e49E6548 — can you check if it's source-verified so I know the code isn't hidden?”
Technical details
Endpoint
GEThttps://mini-tollbooth.onrender.com/verified-contracts?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to quickly confirm whether a specific smart contract's source code has been published and matches the deployed bytecode on Sourcify, across Ethereum mainnet or major L2s (Arbitrum, Optimism, Base, Polygon, Gnosis). It is well-suited for pre-interaction due diligence on DeFi protocols, token contracts, or any on-chain address where transparent source code is a trust signal. Prefer this over a full security audit endpoint when you only need source verification status (not rug-pull scoring, honeypot detection, or simulation) and want a cost-efficient $0.10 lookup.
Side effects
- Missing required 'address' query parameter returns an error
- Invalid or malformed contract address (not 0x hex) returns an error
- Contract not found on specified chain returns UNVERIFIED verdict
- Unsupported chain name returns an error or defaults to Ethereum
- Service unavailable on Render free tier due to cold starts causing timeout
- Payment failure (insufficient USDC or x402 protocol issue) blocks the call
