Payment infrastructure
for AI agents

What we are

Herald Protocol is the infrastructure layer for autonomous agent economics, operating exclusively on the 0G Chain. We provide the settlement primitives that allow AI agents to meter, charge, and pay for digital resources at scale.

We ship an x402 facilitator so any API, MCP server, or agent can accept onchain payments on 0G, and a cross-chain payment router so agents holding funds on 0G can pay services on other chains without managing multiple wallets.
