API v4 Released: Faster, Smarter, Unified

We're excited to announce NSAI API v4 — the biggest platform update since launch. A single endpoint for all threat types, real-time streaming, and dramatically faster responses.

What's New

Unified /api/v4/analyze Endpoint

No more juggling between /api/v3/sms/check, /api/v3/crypto/analyze, and /api/v3/domain/check. API v4 introduces a single unified endpoint that auto-detects the content type:

curl -X POST https://api.noscamai.com/api/v4/analyze \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"content": "Send 0.5 ETH to 0x742d35Cc..."}'

The system automatically identifies this as a crypto-related message & runs the appropriate pipeline — text analysis, crypto wallet check, and URL extraction — all in one request.

SSE Streaming

For long-running analyses, v4 supports Server-Sent Events. Get results as they happen instead of waiting for the full pipeline:

curl -N https://api.noscamai.com/api/v4/analyze/stream \
  -H "Authorization: Bearer YOUR_KEY" \
  -d '{"content": "...", "stream": true}'

Events arrive in order: text_analysis → entity_extraction → crypto_check → final_verdict.

Batch Processing

Analyze up to 100 messages in a single request. Perfect for scanning message logs, email archives, or chat exports:

{
  "batch": [
    {"content": "Message 1...", "id": "msg-001"},
    {"content": "Message 2...", "id": "msg-002"}
  ],
  "webhook": "https://your-server.com/callback"
}

Results are delivered via webhook when the batch completes.

Performance Improvements

Metric	v3	v4	Improvement
Average latency	540ms	180ms	3x faster
P99 latency	2.1s	680ms	3x faster
Throughput	50 req/s	200 req/s	4x higher
Batch support	—	100 msgs	New

Migration Guide

Breaking Changes

1. Base URL: api.noscamai.com/api/v3/* → api.noscamai.com/api/v4/*
2. Response format: threat_level field renamed to risk_level for consistency
3. Auth header: now requires Bearer prefix (v3 accepted raw keys)

Compatibility

v3 endpoints will remain available until June 2026. We recommend migrating before then.

Quick Migration

- POST /api/v3/sms/check
+ POST /api/v4/analyze

- {"message": "suspicious text"}
+ {"content": "suspicious text"}

- response.threat_level
+ response.risk_level
