OpenClaw (ClawdBot)

These examples use the website API host, which currently lists their recommended models. The direct API host can have a different catalog during rollouts. For larger requests or longer runtimes, use https://api.nano-gpt.com/api/v1 with a model from that host’s catalog. See API Hosts for limits and availability checks.
