Tools of Magneta Contract Risk
	Description		Read-only	Idempotent	Open world
`contract_quick_flags`Free, no payment: bytecode-only preview of a deployed smart contract. Covers proxy/upgradeability, ERC-20 probe (name, symbol, owner, paused), risky selectors found in the bytecode (mint, blacklist, fee/tax setters, pause, upgrade), SELFDESTRUCT/DELEGATECALL opcodes, and a partialScore/partialLevel computed from those on-chain signals only. Does NOT cover source verification (Blockscout, Sourcify) nor aderyn static analysis, so partialScore can be lower than the real risk. contract_risk_summary ($0.01 in USDC via x402) is the full report. Read-only, no side effects; an EOA is rejected; identical requests within 10 minutes return the cached result; the HTTP twin GET /v1/flags/:chainId/:address is rate limited to 30 requests per minute per IP.

No	Yes	Yes	Yes
`contract_risk_summary`Analyze a deployed smart contract and return a deterministic risk report: 0-100 score with level (low/medium/high/critical), proxy/upgradeability, owner and pause state, risky selectors found in the bytecode (mint, blacklist, fee/tax setters, pause, upgrade), SELFDESTRUCT/DELEGATECALL opcodes, source verification (Blockscout, Sourcify) and aderyn static-analysis findings. Use it before trading, bridging, approving or integrating a token or protocol contract; Use contract_quick_flags first for a free bytecode-only preview when you are not sure the full report is worth paying for. Use supported_chains first if you are unsure the chain id is covered, and scoring_rubric to interpret the score. Paid: $0.01 in USDC on Base per call via x402. The first call answers with an x402 payment challenge; an x402-enabled client pays automatically and the same call then returns the report. Read-only, no side effects. Error cases (unsupported chain, invalid address, address is not a contract, upstream data source failure or timeout) return an isError result with an error message and are not charged; identical requests within 10 minutes return the cached report.

`scoring_rubric`Return the exact rubric behind contract_risk_summary scores: points per flag, the level thresholds and what each flag means. Free, read-only, no parameters. Call it to explain a score to a user or to decide your own threshold before acting on a report.
