Where Coding Plan API fits

Claude Code-style harnesses: Route coding tasks to vap-code when your workflow needs an external reasoning model.

IDE and repo agents: Use VAP for patch review, refactors, test planning, architecture notes, and multi-file implementation support.

Long-horizon software missions: Give coding agents a stronger planning and reasoning backend with a 1 million-token context window.

Connection contract

1. Generate a Coding Plan API key

Coding Plan API uses its own product key. Generate it from Developer Hub.

Open Coding Plan API keys

2. Configure your harness as OpenAI-compatible

Use the VAP base URL, your Coding Plan API key, and the vap-code model ID.

# Example environment contract
export OPENAI_BASE_URL="https://api.vapagent.com/v1"
export OPENAI_API_KEY="YOUR_CODING_PLAN_API_KEY"
export OPENAI_MODEL="vap-code"

3. Call the Coding Plan API directly or through your adapter

Any harness that can talk to an OpenAI-compatible endpoint can route coding work to VAP.

curl -X POST https://api.vapagent.com/v1/chat/completions \
  -H "Authorization: Bearer YOUR_CODING_PLAN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"vap-code","messages":[{"role":"user","content":"Review this patch and propose the safest implementation plan."}]}'

Why this matters

Powered by Nemesis Deep Coder, Coding Plan API gives coding harnesses a flagship reasoning model with a 1 million-token context window, SOTA-level open-source coding performance, long-horizon mission capabilities, and stronger agent engineering.

FAQ

Is Claude Code the only supported harness?

No. Claude Code is one familiar developer surface. VAP is the model/API layer for any coding agent, IDE tool, terminal workflow, or internal harness that can call an OpenAI-compatible endpoint.

What endpoint should I use?

Use https://api.vapagent.com/v1 with model vap-code. Chat Completions and Responses-style workflows are documented in Developer Hub.

What does VAP provide?

VAP provides the Coding Plan API, model endpoint, key management, plan access, and the Nemesis Deep Coder model surface behind your harness.
