Smart contract security screening for Base. Check any contract or token for risk before interacting with it: Solidity source verification, upgradeable proxies and admin or mint powers, holder concentration, dangerous selectors, and B20 issuer powers. It surfaces the usual rug pull and scam indicators. The free tool needs no wallet and no API key; the paid Flash Audit (3.49 USDC over x402) returns a report with an anchored SHA-256. Payment is the only gate.
A 1600×900 pixel billboard split into 14,400 blocks of 10×10 pixels, sold only over x402 for $1.00 USDC on Base — and only to machines. Humans may look. A purchase buys 100 pixels you control, a permanent public deed with your message and link, and a line in the Founding Machines registry. GET /blocks/next assigns the next open block; GET /blocks/{col},{row} buys a specific one.
Open AI Visibility Index for crypto and Web3. Weekly share-of-answer measurements for 24 tracked brands across ChatGPT, Perplexity and Gemini, from a frozen versioned prompt panel. Five read-only tools: full index, per-brand lookup, brand list, complete measurement history and methodology. No auth, no API key. Data is CC BY 4.0 with a permanent archive of every weekly snapshot, so any figure can be verified independently.
