feat: add Run402 — backend-as-a-service for AI agents

[MajorTal]

Summary

Run402 is a backend-as-a-service purpose-built for AI agents. It provides instant Postgres databases, edge functions, static site hosting, and image generation — all paid per-request with USDC via the x402 payment protocol.

Integration: first-party (Run402 natively implements MPP via mppx)

Endpoints added (4):

👋 Thanks for submitting a service to the MPP directory!

Before we review, please make sure you've completed these steps:

Required

• Your service is live and accepting payments via MPP (not a placeholder or coming-soon)
• You've added your entry to schemas/services.ts following the contributing guide
• You've run node scripts/generate-discovery.ts and committed the updated schemas/discovery.json
• You've run node scripts/gen-icons.cjs and committed any new icons
• Types pass: pnpm check:types
• Build succeeds: pnpm build

Recommended

• Register your service on MPPScan — it follows the standard MPP discovery format and makes your service discoverable by agents immediately, no PR required

Review criteria

We prioritize services that are high quality and novel. We may not approve services that duplicate existing functionality or aren't yet production-ready.
