Ampersend enables LangChain agents to pay for and use remote AI agent services. Give agents tools to:
  • Pay for remote agent services automatically
  • Interact with remote A2A agents

​
How it works

Ampersend provides transparent payment handling via the x402 protocol:
  1. Connect your agent to a wallet with spend controls
  2. Call remote agents via the A2A protocol
  3. Payments are handled automatically when required

​
