Enables AI agents to execute x402 payments with per-task budgets, spending controls, and non-custodial wallets via MCP tools. Use when agents pay for APIs, services, or other agents.
Compares coding agents like Claude Code and Aider on custom YAML-defined codebase tasks using git worktrees, measuring pass rate, cost, time, and consistency.

Spline is a browser-based 3D design tool — think Figma, but for 3D. Designers create interactive 3D scenes (objects, materials, animations, physics, events) in the Spline editor, then export them for the web via a hosted .splinecode file URL.
Before writing any code, check the existing project files to determine the framework.
| Stack | Method |
|---|---|
| Vanilla HTML/JS | <spline-viewer> web component OR @splinetool/runtime |
| React / Vite | @splinetool/react-spline |
| Next.js | @splinetool/react-spline/next |
| Vue | @splinetool/vue-spline |
| iframe (Webflow, Notion, etc.) | Public URL iframe |
The user must go to their Spline editor → Export → Code Export → copy the prod.spline.design URL:
https://prod.spline.design/XXXXXXXXXXXXXXXX/scene.splinecode
Before copying the URL, tell the user to check Play Settings:
Once you have the stack and the scene URL, read the appropriate guide file above and follow its instructions. Always read COMMON_PROBLEMS.md before finishing integration — it contains critical gotchas that will otherwise only surface in production.
