Quartermaster Lens

Description

Read-only toolbar tool to test-drive the x402 API: inspect endpoints, search the Bazaar, preview 402 challenges. Not a wallet. Quartermaster Lens is a read-only companion for the x402 pay-per-call ecosystem. It lets a developer test-drive the Quartermaster API — and any x402 endpoint on the web — right from the toolbar, with no wallet and no risk. Five tabs: • Ask — Type a goal in plain English. The x402 Router shows which tool it would run. Free preview — nothing is paid. • Inspect — Point it at any page and get a scorecard: is it x402-payable? Price, network, asset, pay-to, and what's wrong with the challenge. One click opens the full scored report. • Bazaar — Search the live Coinbase x402 Bazaar and filter by name or URL. • Free tools — Call Quartermaster's free endpoints (hash, UUID, time, IP, x402 test vector). Real results, no payment. • Preview 402 — Request a paid tool WITHOUT paying, decode the exact payment challenge, and copy a ready-to-run snippet to pay it yourself. It is not a wallet: no private keys, no seed phrases, no signing, no custody, no automatic payments. Every action is a plain read-only request. No content scripts. No analytics, no tracking, no data collection. Learn more: https://quartermaster.surewhynot.app/lens
