# How-to: Get listed

> Submit your x402 service for review to appear in the Agent Marketplace catalog and the Discovery API.

List your service in the [Agent Marketplace](/agent-stack/agent-marketplace) so
agents can discover and pay for it. Approved listings appear in both the
[catalog UI](https://agents.circle.com/services) and the
[Discovery API](/agent-stack/agent-marketplace/discovery-api), where agents
filter by category, network, and price.

<Info>
  Listings are reviewed and approved manually today. A self-serve, automated
  submission flow is coming. For now, submit the form below and the team reviews
  your service.

## Prerequisites

Before you begin, ensure that you've:

* Made your service payable: it returns `402 Payment Required` when a request is
  unpaid and serves the resource when paid. See
  [How-to: Become a seller](/agent-stack/agent-marketplace/become-a-seller).
* Published an OpenAPI spec for your service, so agents can read its inputs and
  outputs.
* Confirmed the payout wallet address your service uses. You submit it with the
  form, and it is sanctions-screened during review.

## Steps

<Steps>
  <Step title="Submit the intake form">
    Submit your service details at the [intake
    form](https://forms.gle/7YFzvdmMcn1JH5tF6). Include your endpoint URL,
    payout wallet address, and a short description.
  </Step>

  <Step title="Review">
    The team screens and approves your submission. Your seller payout wallet is
    sanctions-screened as part of review.
  </Step>

  <Step title="Go live">
    Once approved, your service appears in the catalog and is returned by the
    Discovery API. It is then continuously health-checked, so it stays listed
    only while it is reachable. Agents find you through the [Discovery
    API](/agent-stack/agent-marketplace/discovery-api) filters, so make sure
    your metadata makes your service easy to find.
