2026-10-18scoring_rubricadded
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.

Free: list the chains this service can analyze.
after · 15% of words in common
List the EVM chains contract_risk_summary can analyze, as { chainId, name, testnet } objects. Free, read-only, no payment and no parameters. Call it when you need to map a chain name to its id or to check coverage before paying for a report.
2026-10-18contract_risk_summarychangedtitle, description, input schema, annotationsmeaning changed
before
On-chain smart-contract risk report (score 0-100, proxy, owner, risky selectors, source verification, static analysis). Costs $0.02 in USDC via x402.
after · 20% of words in common
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 supported_chains first if you are unsure the chain id is covered, and scoring_rubric to interpret the score. Paid: $0.02 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; failed analyses (not a contract, upstream data source down) are not charged; identical requests within 10 minutes return the cached report.
