A2A Indirect Prompt-Injection & Jailbreak Firewall

Choose this endpoint when your AI agent pipeline ingests untrusted external content — web scrapes, emails, third-party tool responses, or A2A payloads — and you need a dedicated firewall step to detect and strip hidden prompt injections or jailbreak attempts before they reach your LLM. Prefer this over generic content filters when you specifically need protection against adversarial AI manipulation techniques rather than general spam or malware.

• Empty or missing 'text' parameter returns a 400 validation error
• Very large text inputs may exceed query parameter length limits when sent as GET
• False negatives possible if injection patterns are highly obfuscated or novel
• Payment failure (402) if x402 micropayment is not properly attached
• Rate limiting or timeout on unusually long payloads
