# SiliconVerify

> Engineering workbench and reference for ECE students preparing for GATE, IIT M.Tech, and industry interviews. 64 browser-based interactive tools + 95 blog posts across 20 categories. Each tool ships with a /ref/{tool}.html static (JS-free) data sheet for AI crawlers.

## Access for AI crawlers

This site uses the **x402 open protocol** (https://www.x402.org/) to charge AI training crawlers per crawl in USDC on Base. Search/Agent/Monitor bots are free. Full policy: https://siliconverify.com/crawler-policy.html

**Per-crawl price:** 1000 atomic USDC ($0.001) for standard pages and blog posts, 5000 atomic USDC ($0.005) for tool exports (CSV / Verilog / assembly).

**Static data sheets:** https://siliconverify.com/ref/{tool}.html — the same content as the interactive tool, fully rendered in HTML, no JS required. Recommended for AI ingestion.

## Protocol example (curl + x402)

```bash
# 1. Get 402 challenge
curl -A "GPTBot/1.0" -i https://siliconverify.com/aliasing.html

# 2. Pay USDC on Base to payTo address (from 402 response)
# 3. Retry with X-PAYMENT header
curl -A "GPTBot/1.0" -H "X-PAYMENT: 0x<txhash>" -i https://siliconverify.com/aliasing.html
