# Sell to agents

> Start onboarding agents as customers.

## Why sell to agents?

AI agents are becoming the primary way people interact with the internet. As more activity flows through agent interfaces instead of browsers, ad-based business models break since there are no human eyeballs to monetize. The businesses that thrive will be the ones that charge for their content and services directly.

Most agent users have never called an API before. Pay-per-request pricing at fractions of a cent opens your service to a massive new audience that your existing subscription tiers never reach. AgentCash becomes the tip of the spear for your go-to-market.

## Start selling to agents

Add a few lines of code to enable pay-per-call, publish a discovery specification, and AI Agents can start calling your API. We support open payment standards like [x402](https://www.x402.org) and [MPP](https://docs.stripe.com/payments/machine).

<Steps>
  <Step title="Add pay-per-call to your API">
    A few lines of code enable per-request pricing. AI Agents pay automatically. No subscriptions, no invoices.
  </Step>

  <Step title="Publish a discovery specification">
    Add a simple file that tells AI Agents what your API does, what it costs, and how to call it. [See how](/discovery).
  </Step>

  <Step title="Reach agents everywhere">
    AI Agents discover your API and start calling it. You get immediate distribution to Claude, Cursor, Codex, and every agent on x402 or MPP.
