BlockRun
For developers

Pay per call. Two ways in.

One endpoint, 117 models, each priced before it runs. ClawRouter, our open-source router, classifies each request locally and sends it to the cheapest model that can complete it.

$ pip install blockrun-llm
$ export BLOCKRUN_WALLET_KEY=0x… # signs locally, never sent
$ python -c "from blockrun_llm import LLMClient; print(LLMClient().chat('openai/gpt-6-luna', 'Hello!'))"
→ 402  priced before it runs
→ 200  settled · Hello! How can I help?
