A2A Indirect Prompt-Injection & Jailbreak Firewall

Choose this endpoint when your AI agent pipeline ingests content from untrusted external sources — scraped web pages, third-party API responses, MCP tool outputs, A2A payloads, or user-submitted emails — and you need a dedicated security layer to detect and neutralize indirect prompt injections or jailbreak attempts before that content reaches your LLM. Prefer this over manual regex filtering or generic content moderation when the threat model specifically involves adversarial AI prompt manipulation rather than general toxicity or spam.

• Empty or missing 'text' parameter returns a validation error
• Extremely large text inputs may be truncated or rejected
• Sophisticated obfuscated injections may evade detection (false negatives)
• Payment failure via x402 returns HTTP 402 before scan is performed
• Ambiguous or benign-looking injections may produce false positives
• Network timeout if the service is unavailable
