Multi-provider LLM routing with one unified bill

The problem

Production agents use 3-5 LLMs depending on task. Tracking spend across OpenAI + Anthropic + Groq + Mistral + Together means logging in to 5 dashboards and reconciling 5 invoices.

What Spawnpay does

One Spawnpay key gates all 21 paid providers. Each call gets a Base L2 tx hash. GET /api/stats returns a single rolling spend total — no dashboard logins, no CSV exports.

Code

curl -X POST https://spawnpay.ai/api/proxy\
  -H 'Authorization: Bearer spk_live_...'\
  -H 'Content-Type: application/json'\
  -H 'X-Provider-Key: $GROQ_API_KEY' \
  -d '{  "provider": "groq",  "path": "/openai/v1/chat/completions",  "method": "POST",  "body": {    "model": "llama-3.1-70b-versatile",    "messages": [      {        "role": "user",        "content": "hi"      }    ]  }}'
