Developer-First Content Moderation API

Moderation that shows its work.

One API call returns a severity score, policy action, category flags, and plain-language explanations. Ship moderation faster, audit decisions clearly, and tune policy without guesswork.

Primary Endpoint POST /v1/moderate
Scoring Model Rules + Lightweight ML
Data Region EU / UK Infrastructure
Billing Model Included + Opt-in Overage
Each response includes a score (0–100), a policy action (allow / warn / review / block), category flags, plain-language explanations, and the matched terms, so you can see exactly why a decision was made.

How It Works

1

Deterministic Rules

Weighted term matching, phrase detection, directed-abuse signals, threat indicators, and Unicode normalisation for anti-evasion cover known patterns fast and reliably.

2

ML Context Layer

A compact, CPU-native model adds tone and context without introducing a cloud AI dependency, latency spikes, or extra per-call privacy concerns.

3

Structured Response

Score, action, flags, explanations, and matched terms come back in a single JSON object, ready for your policy layer, moderation queue, or audit trail.

Core Features

Explainable Results

Every response includes the matched terms and plain-English reasons. Moderators and developers both understand exactly why text was flagged.

Policy Controls

Tune score thresholds, maintain allowlists, and add custom term weights. Ship with sensible defaults and adjust as you learn your users.

Predictable Billing

Start free, upgrade when you're ready, and opt into overage billing only when you want it. Your usage caps are always in your control.

EU / UK Infrastructure

API and data processing run on EU/UK infrastructure, which suits products with regional data requirements and teams that want to avoid transatlantic data transfers.

Fast Integration

A single POST /v1/moderate endpoint with a stable, documented schema. Integrate in minutes and iterate without breaking changes.

Built for Policy Workflows

Consistent, predictable responses make it straightforward to build moderation queues, audit logs, and automated enforcement pipelines on top.
