Vibe Coding with Claude Code
Anthropic's agentic coding tool — runs in your terminal, edits your files, ships your app.
What is Claude Code?
Claude Code is Anthropic's terminal-based AI coding agent. It dropped in early 2025 and immediately stood out — it doesn't just suggest code, it reads your repo, edits files, runs commands, and commits changes. All from your terminal.
The big difference is reasoning. Claude thinks before it writes. It plans multi-step changes, handles complex refactors, and catches edge cases that other tools miss. When you give it a task like "add authentication to this app," it actually thinks through the full implementation.
Builders love Claude Code because it acts like a senior engineer on your team. Point it at a problem, let it work, review the diff. It's pair programming without the scheduling.
Why Claude Code + YepAPI?
Agentic builds
Claude Code reads your repo, plans the implementation, and writes multi-file changes.
Full API access
Give it llms.txt and it calls any of YepAPI's 100+ endpoints without guidance.
Terminal-first
No IDE needed. Claude Code runs in your terminal and edits files directly.
Claude Code is the most capable reasoning model you can point at code. Give it YepAPI's llms.txt and it understands the entire API surface — endpoints, parameters, auth, response shapes. Ask it to build a rank tracker and it writes the API calls, parses the responses, builds the UI, and handles errors.
The terminal workflow is powerful. You stay in your flow, describe what you want, and Claude does the rest. No context switching, no copy-pasting. It's the closest thing to having a senior engineer who never sleeps and knows every API by heart.

What you can build
Frequently asked questions
Just include our llms.txt URL in your prompt or project context. Claude Code reads it automatically and understands every endpoint. Then just ask it to build whatever you need.
Absolutely. Claude Code handles multi-file edits, so it can scaffold a full app — routes, API calls, UI components, error handling — all from a single prompt. It's not just snippets, it's full implementations.
Claude Code requires an Anthropic subscription. YepAPI gives you $5 free credit on signup — no credit card needed. So you can start building real apps right away without paying for API calls.
