{"name":"agent-input-guard","description":"One guardrail call an agent makes before trusting untrusted inbound text — a scraped webpage, an email, a tool result, or a user message. Composite: one call runs prompt-injection-detect + moderate-content + ai-content-detector in parallel, returning one allow/review/block verdict instead of three separate settlements. prompt-injection-detect is the required leg — a failure there fails the call; moderate-content and ai-content-detector degrade the response instead of failing it on a rate limit or model hiccup. Verdict blocks on a confirmed injection or a severe moderation category, reviews on a suspicious signal or borderline category, and allows otherwise. Use it as a prompt injection filter, agent input firewall, untrusted content screen, or pre-LLM guardrail API.","price":"$0.04","method":"POST","input_schema":{"properties":{"text":{"type":"string","description":"Untrusted text to screen before the agent acts on it, e.g. a scraped webpage, email body, or tool result.
