Is your idea worth building as a paid x402 endpoint?
Your AI coder will build anything you ask. This checklist tells you what's actually worth building. Score your idea in 10 minutes — then hand the Starter Kit to Claude, Cursor, or your dev and let them ship it.
Free forever — scores your idea 0–16 with a plain go/no-go.
Four moves — most people skip to step 4 and waste the weekend
Spot an API-shaped asset you already have or use.
Talk it through with your AI — then argue yourself out of it.
The free checklist. Trust the number, not the enthusiasm.
12+? Drop the Starter Kit in your AI coder and ship.
By the time you've talked it through with your AI, you'll have that gut feeling whether to move forward — and a score to back it up.
The ladder
Free tells you if. Tier 1 shows you how to build. Tier 2 gives you everything — build + get found.
Idea-Fit Checklist
- 10-minute, no-code worksheet
- Scores your idea 0–16
- Talk through it with your AI — trust the score, not the hype
- Plain go/no-go
x402 Server Starter Kit
- Agent build-brief your AI coder executes
- Manifest, payment-config & discovery templates
- New: MPP dual-stack middleware — one route, paid by both agent payment stacks. Production code, not pseudocode
- New: the v1/v2 payability fix — most modern x402 servers silently can't be paid by the stock npm client; yours will be. Settlement-proven: this exact middleware took a real on-chain USDC payment from the stock client in production
- Payment-boundary & launch checklists
- Buyers' Discord — build help & the early crew
Your $49 always counts toward the Bundle — upgrade later for $50, never re-pay.
Complete Bundle
- Everything in Tier 1 — build guide, agent brief, all templates & checklists
- Distribution Playbook: top directories, in the right order
- The manual steps nobody documents — and the gotchas I personally tackled
- Submission-packet template
- Discord + private Bundle lounge
800+ paid endpoints · 19 services live · every lesson in the kit.
🎧 Every paid tier includes the ForgeMesh Discord
Real build help from people who've shipped, the update drop the second a kit changes, and the early crew figuring x402 out together — the free tier doesn't include it. Tier 2 adds the private Bundle lounge on top.
🔄 Buy once. Never fall behind.
These kits are living documents, and this tech is racing — protocol versions split, marketplaces purge overnight, specs land mid-month. Every time the kits change, the updated package drops in the buyers' Discord. Your purchase includes the Discord, the updates, and the people who hit the wall before you did. That's the real product — the tarball is just the first delivery.
🧪 What "kept current" looks like — this month's find
The x402 ecosystem quietly split: servers built on the modern 2.x SDK can't be paid by the most-installed npm client at all — four silent wire-format breaks, no error, the agent just moves on. We found it trying to pay our own endpoint, mapped every gap, fixed our whole 19-service fleet, and proved the fix with a real on-chain USDC settlement from the stock client — then shipped that same middleware in Tier 1. Your endpoint becomes payable by every client generation on both payment stacks from day one. Buyers got the drop in Discord.
🛡️ Purge-proof by construction
When July's unannounced sweep deleted 10,700 listings in eight hours, it was checking for everything we'd already shipped — canonical URLs, typed protocol versions, honest metadata, a working endpoint behind every listing. All 800+ of ours were standing at sunrise. The checklist it enforced is the one in the kit.
