Fast pre-payment sanity check for agents on Base: confirms the RPC reports Base mainnet (chain ID 8453) and that the official USDC contract has deployed code. No request body. Returns PASS or FAIL with both checks and a timestamp. It is not a token-risk report, transaction simulation or payment proof.

Token-risk report for one Base ERC-20 contract. Checks whether the token can be sold (honeypot simulation), buy/sell/transfer tax, owner privileges (mint, pause, blacklist, balance changes, proxy upgrades), holder concentration and DEX liquidity. Returns ALLOW, WARN, BLOCK or INCOMPLETE with scored findings and per-check coverage. INCOMPLETE means required evidence was unavailable, never zero risk. Read-only: never signs or trades.

Simulate one unsigned Base transaction before an agent signs it. Runs eth_call and gas estimation on current chain state, decodes the intent (ERC-20 transfer, approve, NFT setApprovalForAll), flags unlimited approvals, calldata sent to a non-contract, zero-address targets, reverts and destination risk labels such as phishing or sanctions. Returns ALLOW, WARN, BLOCK or INCOMPLETE with findings. No key or signed transaction is requested.

Verify one Base USDC payment onchain before an agent releases goods or credit. Reads the transaction receipt and checks the official USDC Transfer logs against the expected recipient, amount and optional sender. Returns VERIFIED, MISMATCH, FAILED or PENDING_OR_NOT_FOUND with block number, confirmations, the matching transfer and a Basescan link. Read-only: never moves funds.
