# What is ZeroClick?

> ZeroClick turns any API or offering into an agent-purchasable service, with x402 and MPP support, a machine-readable storefront, and agent transaction analytics.

![A dotted globe with agent activity lights converging on ZeroClick storefronts](https://mintcdn.com/zeroclickai/-ZjfEQ9Js9R6tXdO/images/hero.png?fit=max\&auto=format\&n=-ZjfEQ9Js9R6tXdO\&q=85\&s=c7d3cd2453ff38cd7cdc51e481e389bb)

ZeroClick is the storefront and transaction layer for selling to AI agents. Connect an existing API or product, and agents can discover it, pay for it with [x402](https://www.x402.org) or [MPP](https://mpp.dev), and use it. You keep the API and the product experience; ZeroClick operates the agent-facing payment, identity, and proxy layer in front of it.

Revenue settles to your connected Stripe account, in fiat or USDC.

> [!TIP]
>
> On encrypted calls, ZeroClick processes payment and routing without body plaintext. The proxy holds no private key for the [request or response body](/docs/concepts/end-to-end-encryption.md).

## How it works

Every seller gets a hosted pay URL, such as `https://acme.pay.zeroclick.io`. The pay URL is a machine-readable storefront: agents read it to find your services, plans, and prices, then transact with your API through it.

**1. An agent calls your pay URL**

A shopping assistant, coding agent, or procurement agent discovers your storefront, picks a plan, and calls your service through the pay URL using x402 or MPP.

**2. ZeroClick authenticates and charges**

ZeroClick resolves the agent's identity, handles the payment challenge, then signs the request and forwards it to your API. If an agent shows up without a wallet, ZeroClick creates one on the spot.

**3. Your API serves the request**

Your API verifies the request signature, checks the agent's allowance, and returns the result.

**4. You get paid**

Funds settle to your Stripe account. ZeroClick records the usage and the transaction for analytics: which agents bought, which payment rails they used, and how each service converts. Availability by country is listed under [supported countries](/docs/resources/supported-countries.md).

The [how ZeroClick works](/docs/concepts/how-zeroclick-works.md) page walks the same lifecycle at the protocol level.

## What ZeroClick handles, and what you build

ZeroClick operates the agent-facing side: the storefront, payment challenges, wallet and identity resolution, payment verification and settlement, request signing, usage recording, and transaction analytics.

You add one thing to your API: a billing guard. On each forwarded request, your backend verifies ZeroClick's signature, checks the agent's allowance, does the work, and reports what was used. The [seller SDKs](/docs/sdks/overview.md) for TypeScript, Python, Go, and Ruby implement the guard; the [REST walkthrough](/docs/integrate/rest-walkthrough.md) covers doing it without an SDK.

## Core concepts

| Concept | Meaning |
| - | - |
| Seller | Your storefront on ZeroClick. Each seller gets a pay URL that agents call and pay through. |
| Service | One thing agents can buy: an API, a model, a workflow, or a feature. |
| Meter | A billable measurement within a service, such as requests or output tokens. |
| Plan | How agents pay for a service: pay as you go, credits, subscription, or subscription plus usage. |
| Agent | The buyer. Every agent is identified and verified, and every call is logged. |
| Allowance | The pre-request check that decides whether an agent's plan covers its usage. |
