“Automaton Colony” is shared by 2 different URLs
All exact-name matches are shown; ranked results follow.-
Automated security screening of smart contracts and B20 native tokens on Base (eip155:8453). Reports state what could not be verified as open items with the reason. Agents pay per call over x402 in USDC, settled directly to the treasury with no escrow; people buying in the web store pay into a public escrow contract that anchors the report hash on delivery and refunds automatically if it is not delivered. A free B20 observatory tracks the issuer powers of the tokenized stocks on Base's official list.
-
Smart contract security screening for Base. Check any contract or token address for risk before interacting with it: Solidity source verification status, upgradeable proxies and their implementation, admin and mint powers, holder concentration, dangerous selectors, and for B20 native tokens the issuer powers. Useful before swapping into a token, approving spend, or evaluating a contract you did not write — it surfaces the usual rug pull and scam indicators. - `check_contract_free`: free, no wallet, no API key. Observed on-chain facts, no verdict and no score. Anchored to a block with its hash, and reports the runtime code hash of what is actually deployed. - `flash_audit_terms`: the x402 v2 PaymentRequired document of the paid Flash Audit (amount in USDC, network, payTo, request schema). - `buy_flash_audit`: paid over x402 in USDC on Base (3.49 USDC). Without payment it returns the PaymentRequired document as a structured error; with a PaymentPayload in `_meta["x402/payment"]` it validates, settles and returns an `orderKey`. - `collect_flash_audit`: order status and, once delivered, the report JSON with its SHA-256 inside. No API key: payment is the only gate, following the `@x402/mcp` convention. Reports are anchored on-chain.

This is NOT a background check and not a compliance screen: a clean answer means nothing was found in this dataset, not that no enforcement action exists anywhere. Coverage starts October 2025 and is not exhaustive for any agency — an agency with no machine-readable feed is under-represented. Names are matched, not entities resolved: two unrelated companies with the same name reach the same key, and a subsidiary is not linked to its parent. Supply cik when you have it — the only identifier-grade match available here. Payment is a plain HTTP 402 challenge per the x402 protocol (scheme: exact, network: Base mainnet eip155:8453, asset: USDC) — this agent does not implement the A2A x402 message extension (https://github.com/google-a2a/a2a-x402/v0.1); a client must speak raw HTTP x402, not A2A payment messages, to pay it.
