What is Content Moderation on reApi?
Content Moderation is the omni-moderation-latest model: it takes text, image URLs, or both in one request and returns a flagged verdict with 13 per-category scores and the input types each category was applied to. One async call handles a single string, a batch of strings, or a mixed text-and-image submission, and every request is billed per moderation unit — 1,000 words of text or one image.
What you can build with this model
Real-world workflows and production use cases you can build and ship with this model.
Moderate a live community feed with Content Moderation
Comments, chat messages, forum posts and reviews arrive faster than any team can read them. Content Moderation screens each one against harassment, hate, violence, sexual content, self-harm and illicit categories and returns a flagged verdict with a score per category, so your pipeline auto-approves the obvious, holds the borderline for a human, and blocks the clear violations. Batch a whole page of comments into one call — Content Moderation returns one result per string.
Check some content
Screen images and captions together before they publish
A photo and its caption can be harmless apart and abusive together. Content Moderation accepts a mixed input — text blocks plus image URLs in one request — and scores the combination as a single item, reporting which categories were evaluated against the image and which against the text. Put Content Moderation in front of your upload endpoint so user-generated media never reaches the CDN unchecked.
Backfill and audit content at pipeline scale
Re-screen an archive, audit a partner's catalog, or QA the output of your own generation models. Content Moderation bills per moderation unit — 1,000 words of text or one image — and rounds the bill up once per request, so large batches cost less per item than single calls. Same task id, same poll endpoint, same credit ledger as every other reApi model, so Content Moderation drops into an existing worker without new infrastructure.

Why reAPI
13 categories, one verdict
Content Moderation reports harassment, harassment/threatening, hate, hate/threatening, illicit, illicit/violent, self-harm, self-harm/instructions, self-harm/intent, sexual, sexual/minors, violence and violence/graphic — each as a boolean plus a 0–1 score — and a single flagged decision on top. Tune your own thresholds on the scores when the default verdict is too coarse.
Text, images, or both in one request
Send a string, an array of strings, or an array of text and image_url blocks. Content Moderation tells you which input types each category was applied to, so a mixed submission is scored as one item rather than two disconnected checks. Content Moderation takes image URLs only — no base64 uploads to manage.
Priced per unit, rounded once
1 credit equals $0.001 USD. Content Moderation bills one unit per 1,000 words of text (each text item counts as at least 50 words) and one unit per image, then converts the total to credits once per request. Failed requests are refunded automatically; polling is free.
Content Moderation vs Azure AI Content Safety
Both screen text and images for harmful content. They differ in how many categories they report, how a result is shaped, what a billable unit is, and how much setup sits between you and the first call.
Capability
Content Moderation on reApi
Azure AI Content Safety
Categories
13 categories — harassment, hate, illicit, self-harm, sexual and violence families with sub-categories — each a boolean plus a 0–1 score.
Four harm categories (hate, sexual, violence, self-harm), each with a 0–7 severity level; images return the trimmed 0/2/4/6 scale.
Text and images together
One request mixes text and image_url blocks and is scored as a single item; Content Moderation reports which input types each category applied to.
Separate Analyze Text and Analyze Image APIs; a combined multimodal API is in preview.
Billable unit
Per 1,000 words of text or per image, converted to credits once per request; failed requests refunded.
Per text record of up to 1,000 Unicode code points, and per image; a 7,500-character input counts as eight records.
Batching
An array of strings returns one verdict per string from a single Content Moderation task.
One text record or one image per call; the text API defaults to a 10K-character maximum, so longer inputs are split.
Getting started
One API key on the same account, endpoint and credit ledger as every other reApi model.
An Azure subscription plus a Content Safety resource created in a supported region before the first call.
Free usage
Pay-as-you-go from the first call; signup credits cover a first batch of Content Moderation checks.
A free tier of 5,000 text records and 5,000 images per month that stops serving when the limit is reached.
Comparison reflects publicly documented behavior at the time of writing (Azure AI Content Safety pricing and Learn pages, retrieved 2026-08-29). Category coverage and thresholds are set by each model and may change over time.
Integrate Content Moderation in three steps
- step 01
Create an API key
Sign up at reApi and grab a key. Signup credits cover plenty of Content Moderation checks — enough to validate the verdicts against content you already know the answer for.
Open - step 02
Submit content to check
POST to /api/v1/moderations with model: omni-moderation-latest and your input — a string, an array of strings, or text and image_url blocks. Content Moderation returns a task id immediately.
Open - step 03
Poll for the verdict
GET /api/v1/tasks/:id until status is completed. The response carries moderation.results — flagged, categories, category_scores and category_applied_input_types for each input item.

Rejected synchronously with the failing field named. Check enum values, ranges, and URL fields — nothing is charged.
Authentication or balance issue
401 means a missing or invalid Bearer key; 402 means the reserve exceeds your balance. Manage keys and credits in the console.
Content or material rejected
Reference material and outputs pass automated moderation. Rejected tasks fail with a clear error and a full refund.
Task failed or timed out
A task that reaches a failed state is never charged — the reserve refunds automatically. Keep the task id and retry when ready.
