Agent security API for autonomous tool calls

Pay-per-call x402 security tools for tool-call preflight, prompt-injection detection, response sanitization and schema-drift detection.

Paid endpoints support x402 V2 with USDC on Base or Solana mainnet. Check the returned HTTP 402 payment requirements and network before paying; prepaid credits and subscriptions use separate authorized checkout flows.
