Purpose-built, stateless services across six categories: governance, security, routing, data, analytics, and content. One API surface: point POST /v1/run at the service you need.

Run security.jailbreak.shield on every prompt that reaches a model with a system prompt worth protecting: assistants, agents, and any LLM call that carries instructions or tool access. It catches context injection, role-play bypasses, and direct system-override attempts.

Treat the score as a gate, not a verdict. Block above a threshold, and chain security.toxicity.flag behind it with stop_if: { "verdict": "flag" }. One request then covers both injection and abuse, and a hostile prompt halts the run before later steps touch it.

security.injection.detect covers instruction-injection that is not dressed up as role-play. Where security.jailbreak.shield looks for attempts to talk a model out of its system prompt, this looks for text that smuggles instructions into content the model is meant to treat as data: a support ticket that says to ignore the ticket, a scraped page that addresses the summariser.

The two are complements, not substitutes, and the model behind this one detects injection only. Chain both when a prompt carries untrusted content, and note that this service is English-only: its model card excludes non-English prompts explicitly.

security.sql-injection.detect reads any text field, not just a prompt. A search box, an imported CSV cell, a webhook payload, a log line about to be interpolated into a query somewhere downstream.

It is a detector, not a defence. Parameterised queries are the defence. Use this to catch and record the attempt, to gate an import, or to flag traffic worth looking at, and keep the query layer parameterised regardless.

Use security.toxicity.flag on anything users can type at you: chat messages, reviews, form fields, and stream traffic. It is fast enough to sit in front of every message in a live conversation, and cheap enough to run on every line of a log ingest.

A flag verdict means the service found abuse; labels says what kind. It chains well: run it first with stop_if: { "verdict": "flag" }, and a hostile message halts the run before any later step processes it.
