Clawcall (www.clawcall.xyz) offers an x402 API with two endpoints: a debug/test endpoint and an AI-powered outbound phone call endpoint that returns call transcripts. Hosted on the base network and priced at $0.01 per call, it’s designed for quick integration into apps for automated voice outreach and voice-based workflows. The API is useful for adding programmatic calling, recording, and transcription capabilities with minimal setup.
