LiteLLM alternative with on-chain receipts

The problem

LiteLLM is a routing proxy you self-host. Great unification, but you still need a billing layer on top — and you still need to deploy + maintain LiteLLM yourself.

What Spawnpay does

Spawnpay is hosted, BYOK, and includes billing + on-chain receipts out of the box. Use them together (LiteLLM for model routing, Spawnpay as the LiteLLM upstream) or replace LiteLLM entirely. Full comparison: /vs/litellm.

Code

curl -X POST https://spawnpay.ai/api/proxy\
  -H 'Authorization: Bearer spk_live_...'\
  -H 'Content-Type: application/json'\
  -H 'X-Provider-Key: $OPENAI_API_KEY' \
  -d '{  "provider": "openai",  "path": "/v1/chat/completions",  "method": "POST",  "body": {    "model": "gpt-4o-mini",    "messages": [      {        "role": "user",        "content": "hi"      }    ]  }}'
