Let an agent wire it up

Working in Claude Code, Codex or Gemini CLI? Paste this. It points the agent at /llms.txt . The whole integration written for a machine: base URL, auth header, where model slugs come from, every error code and which of them are worth retrying.

cURLpaste into your agent

Read https://routehook.ai/llms.txt and wire this project up to
Routehook exactly as it specifies. Use my ROUTEHOOK_API_KEY from the
environment, pick a model slug from GET /v1/models rather than guessing one,
and only add retry logic for 429 and 503.

Your first request

Every endpoint takes the same bearer token and returns JSON. Swapping models is a change to one string.

cURL

curl https://api.routehook.ai/v1/chat/completions \
  -H "Authorization: Bearer $ROUTEHOOK_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "your-model",
    "messages": [
      { "role": "user", "content": "Hello" }
    ]
  }'

The response

The last two fields are on every response: what the call cost you, and what the same call costs at the provider’s published price.
