Small tools and writing for people shipping x402 paid endpoints — plus a done-for-you setup service.

Free tools

• Tailwind v3 → v4 migration auditor — paste your tailwind.config.js and a grep of your class names; get the exact @theme CSS, per-plugin v4 status, every renamed utility you still use, and the silent runtime changes. No signup, nothing stored.
• ESLint .eslintrc → flat config auditor — paste your .eslintrc.{js,json}; get each legacy key mapped to its flat-config home, which extends have a flat build vs. need FlatCompat, and a generated eslint.config.js skeleton. No signup, nothing stored.
• x402 v2 validator — paste the URL of a paid endpoint and get a field-by-field grade of its 402 challenge and discovery contract against the x402 v2 spec and the x402scan discovery rules.

Writing

• What npx @tailwindcss/upgrade leaves broken — the 20% of a v3→v4 migration the official codemod skips.
• The ESLint flat-config migration has no codemod — why FlatCompat isn't a migration, and the seven keys you convert by hand.
• Paying an x402 endpoint from scratch — how far a hand-rolled exact-scheme buyer gets, and what breaks.
• Why x402scan isn't listing your endpoint — a debugging checklist for v2 endpoints that submitted fine but never got indexed.
• Migrating an x402 endpoint from v1 to v2 — every field that changed, and why x402scan rejects a v1 payload.

Done for you

x402-enable your API — I add a facilitator-free x402 v2 payment layer to your HTTP service and hand it back as a reviewable pull request. Fixed price, paid in USDC on Base. $75–$150 depending on scope.
