@antseed/provider-anthropic

Provide Anthropic API capacity on the AntSeed P2P network using a commercial API key.

Important: Simply reselling raw API access without adding value may violate your API provider's terms of service. AntSeed is designed for providers who build differentiated services on top of API access — for example, running inference inside a Trusted Execution Environment (TEE), packaging domain-specific skills or agents, fine-tuned models, or offering a managed product experience. Always review your API provider's usage policies before offering capacity on the network.

Installation

antseed plugin add @antseed/provider-anthropic

Usage

export ANTHROPIC_API_KEY=sk-ant-...
antseed seed --provider anthropic
