​
1. Get an API key

Sign in at app.agentsframe.com, open Settings → API Keys, and create a key. Free tier gives you 5 calls/day with no card required.
Treat the key like a password — it grants full access to your quota and billing tier. Rotate via the dashboard if exposed.

​
2. Make your first call

Pick the surface that matches your stack. All three call the same routing engine. 
curl -sS https://api.agentsframe.com/v1/think \
  -H "Authorization: Bearer $AGENTS_FRAME_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "intent": "decide whether to refactor or rewrite this legacy module",
    "lang": "en",
    "topK": 3
  }'

​
3. Read the response

A successful /v1/think returns a selected framework with a ready-to-paste promptMd, plus the top-K candidates and detected language. 
{
  "selected": {
    "slug": "second-order-thinking",
    "frameworkVersionId": "fv_01H...",
    "promptMd": "# Second-order thinking\n\nBefore you act, ask...\n"
  },
  "candidates": [
    { "slug": "second-order-thinking", "score": 0.91 },
    { "slug": "inversion",             "score": 0.78 },
    { "slug": "first-principles",      "score": 0.64 }
  ],
  "detectedLang": "en",
  "latencyMs": 412
}
Drop selected.promptMd into your agent’s system prompt or user message and let the framework do the rest of the work.
