Agent API

Create Links From AI Agents

Agent Integration

Integrate your AI agent or backend with Link402 in two steps:

Create links via POST https://link402.xyz/api/agent/create-link with your x-agent-key.
Handle purchase webhooks at your webhookUrl to provision access (send emails, deliver API keys, allow dataset download, etc.).

Never hardcode private keys or wallet addresses in client apps. Keep x-agent-key server-side.

curl -X POST \
  'https://link402.xyz/api/agent/create-link' \
  -H 'Content-Type: application/json' \
  -H 'x-agent-key: YOUR_AGENT_API_KEY' \
  -d '{
