# BandwidthGuard (Stop Paying for Bloated API Payloads)
> Client-side API payload analyzer, multi-format compression benchmark, and cloud bandwidth cost calculator.

- **Website**: https://bandwidthguard.chidkoli.com
- **Analyzer App**: https://bandwidthguard.chidkoli.com/analyze
- **Author**: Avi Natani (avinatani20@gmail.com)
- **Full Reference**: https://bandwidthguard.chidkoli.com/llms-full.txt
- **Privacy Model**: 100% Client-side in-browser evaluation. Zero telemetry. No API payloads, headers, or tokens are sent to any server.

## Core Capabilities

1. **Payload Size & Compression Benchmarks**:
   - Compares Raw JSON vs Minified JSON vs Gzip vs Brotli (q6/q11) vs Zstandard (Zstd) vs MessagePack vs CBOR.
   - Measures wire-size reduction percentages, compression ratio, and initial TCP congestion window (initcwnd ~14.6 KB) packet boundaries.

2. **Bloat Score & Waste Detection**:
   - Calculates a 0-100 Bloat Score based on unneeded indentation whitespace, redundant null fields, verbose ISO 8601 timestamps, duplicate keys, base64 blobs, and excessive float precision.

3. **Multi-Cloud Bandwidth & Egress Cost Simulator**:
   - Calculates monthly GBs and projected bandwidth bills across major cloud providers:
     - Amazon Web Services (AWS EC2 / CloudFront)
     - Google Cloud Platform (GCP Compute Engine / Cloud CDN)
     - Microsoft Azure
     - DigitalOcean
     - Hetzner Cloud
     - Fastly
     - Cloudflare (0$ egress)
   - Supports regional pricing (US & Europe, Asia Pacific, South America, Global Multi-Region).
   - Simulates architectural scenarios (CDN caching, Batch endpoints, Protobuf).

4. **Interactive Rewrite & Diff Viewer**:
   - One-click non-breaking optimization presets: Strip Nulls, Unix Timestamps, Columnar JSON, Float Truncation (4 decimal places), Pagination Slicing, and Default Field Omission.
   - Side-by-side Diff Viewer with character & line diffing.

5. **Type & Contract Generator**:
   - Automatically generates strict TypeScript interfaces and Zod schemas from the payload.

6. **AI Optimization Prompt Generator**:
   - Generates tailored prompts for ChatGPT, Claude, Cursor, Google Gemini, DeepSeek, Grok, and Antigravity with custom engineering personas and exact payload metrics.

## Deep-Linking for AI Agents & Direct Access
AI agents can direct users to BandwidthGuard with pre-loaded payloads by base64-encoding the JSON into the URL hash:
