Drop-in Replacement

Perspective API is Retiring. We're Ready.

Google's Perspective API shuts down December 31, 2026. Migrate to moder8r with a single line change — same endpoints, same JSON, same client libraries.

Migrate in 3 Steps

1

Create an Account

Sign up for free at moder8r.app and generate an API key from your dashboard.

2

Change One Line

Replace commentanalyzer.googleapis.com with perspective.moder8r.app. That's the only code change.

3

Done

Same request format, same response shape, same client libraries. Everything just works.

One Line Change

Just swap the hostname. The request and response are identical.

curl

Before (Google)

curl -X POST \
  'https://commentanalyzer.googleapis.com/v1alpha1/comments:analyze?key=YOUR_GOOGLE_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
    "comment": { "text": "You are terrible." },
    "requestedAttributes": { "TOXICITY": {} }
  }'

After (moder8r)

curl -X POST \
  'https://perspective.moder8r.app/v1alpha1/comments:analyze?key=m8r_sk_YOUR_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
    "comment": { "text": "You are terrible." },
    "requestedAttributes": { "TOXICITY": {} }
  }'

Node.js

Before (Google)

const url = 'https://commentanalyzer.googleapis.com/v1alpha1/comments:analyze?key=' + API_KEY;

const res = await fetch(url, {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    comment: { text: 'You are terrible.' },
    requestedAttributes: { TOXICITY: {} }
  })
});

After (moder8r)

const url = 'https://perspective.moder8r.app/v1alpha1/comments:analyze?key=' + API_KEY;

const res = await fetch(url, {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    comment: { text: 'You are terrible.' },
    requestedAttributes: { TOXICITY: {} }
  })
});

Python

Before (Google)

from googleapiclient import discovery

client = discovery.build(
    "commentanalyzer", "v1alpha1",
    developerKey=GOOGLE_API_KEY
)

After (moder8r)

from googleapiclient import discovery

client = discovery.build(
    "commentanalyzer", "v1alpha1",

Key Differences from Google

Score Precision

Full-precision floats from the underlying model, not rounded to 3 decimal places like Google's API.

Span Annotations

When enabled, spans are identified by GPT-4.1 Nano. Character offsets are approximate (~200-500ms extra latency).

Approximate Attributes

SPAM, INCOHERENT, and UNSUBSTANTIAL are scored by a GPT-4.1 Nano classifier with binary confidence (high/low).
