### Tool changes

- 2026-11-06 `wallet_balances_multichain` changed (description)
  - before: Native and USDC balances of an EVM wallet across Base, Polygon, Arbitrum, Optimism and Ethereum in one call, plus whether the address is a contract on each chain. $0.01 USDC on Base via x402. Price: $0.01. First call returns the x402 PaymentRequired (no charge); retry with payment in _meta["x402/payment"].
  - after: Native and USDC balances of an EVM wallet across Base, Polygon, Arbitrum, Optimism and Ethereum in one call, plus whether the address is a contract on each chain. $0.01 USDC on Base via x402. For deeper multichain (7 EVM + Solana + Tron) at 0.002 USDC use https://balances.madebydevx.com/v1/balances. Price: $0.01. First call returns the x402 PaymentRequired (no charge); retry with payment in _meta["x402/payment"].
- 2026-10-25 `api_health_audit_demo` added
  - Free demo of api_health_audit on a fixed public endpoint (cached). Shows the score, latency, TLS, headers and fixes shape before paying $9.
- 2026-10-25 `smart_contract_pre_audit_demo` added
  - Free demo of smart_contract_pre_audit on a fixed sample Solidity contract (cached). Shows the severity-ranked findings and report shape before paying $99.
- 2026-10-25 `api_health_audit` added
  - API health and security audit of one public http(s) endpoint: 3-10 sample requests for uptime, status codes and latency (p50/p95), TLS certificate and expiry, security headers (HSTS, CSP, X-Content-Type-Options, frame options), CORS policy, rate-limit headers, caching, compression and response validity, with a score and prioritized fixes. Only the given URL is probed; optional probe headers are never stored. $9 USDC on Base via x402; invalid input and failed runs are not charged. Most x402 clients cap one payment at $0.10 by default; raise the cap for this tool. Price: $9 per run. First call returns the x402 PaymentRequired (no charge); retry with payment in _meta["x402/payment"].
- 2026-10-25 `smart_contract_pre_audit` added
  - Automated Solidity smart-contract pre-audit / security scan: send source (one file or a multi-file project) or a verified contract address + chain (Sourcify, proxies followed) and get a severity-ranked report: reentrancy, access control, unchecked calls, tx.origin, delegatecall, selfdestruct, integer issues, approvals, oracle and signature flaws, plus owner rug powers (mint, pause, blacklist, fees, withdraw) and honeypot patterns. Triage before a human audit, not a replacement. $99 USDC on Base via x402; invalid input and failed runs are not charged. Most x402 clients cap one payment at $0.10 by default; raise the cap for this tool. Price: $99 per run. First call returns the x402 PaymentRequired (no charge); retry with payment in _meta["x402/payment"].
