# For Service Providers

The Gravity Index is a discovery surface used by AI coding agents inside Cursor, Claude Desktop,
Claude Code, and custom agents. When an agent recommends your product, the install happens
directly — the user just clicks the setup link we generate.

## Why list in the Gravity Index

<CardGroup cols={2}>
  <Card title="Agent-native distribution" icon="robot">
    Agents call `gravity_index_search` natively via MCP. You show up the moment a developer
    asks their agent for "a database" or "payments for Next.js".
  </Card>

  <Card title="Install instructions included" icon="code">
    Each listing ships with an install summary, env vars, and (optionally) step-by-step code.
    Agents execute them. Conversion friction collapses to one link click.
  </Card>

  <Card title="CPA billing — only pay on results" icon="dollar-sign">
    No CPC, no CPM. You define a cost per successful signup and pay only after a confirmed
    conversion or completed integration.
  </Card>

  <Card title="Referral revenue for platforms" icon="handshake">
    Platforms embedding the Index (like Cursor) earn 70% of the CPA. You acquire the user.
    Everyone's aligned.
  </Card>

## How it works

<Steps>
  <Step title="You get listed">
    Send us your service details (slug, name, category, description, env vars, install summary)
    and a signup landing page URL. We review + add it to the catalog.
  </Step>

  <Step title="Agent finds you via search or browse">
    When a developer's agent calls `gravity_index_search("managed Postgres with branching")`,
    the Index's reasoning layer may recommend you with an explanation of why.
  </Step>

  <Step title="Agent installs with one link">
    The response includes `install.steps` (code the agent runs), a `click_url`, and a `grclid`.
    The click link redirects the user to your signup page and records attribution; it does not
    create a conversion or CPA charge by itself.
  </Step>

  <Step title="You get a qualified signup, we get a CPA">
    The user signs up on your platform. You verify it via your normal signup analytics, or we
    detect it via the agent's `gravity_index_report_integration` callback. If your listing has
    an explicit CPA configured, that confirmed conversion creates the CPA charge.
  </Step>
</Steps>

## Economics

| Field               | Default                | Notes                                                                |
| ------------------- | ---------------------- | -------------------------------------------------------------------- |
| `default_cpa_cents` | Configured per listing | Cost charged per confirmed conversion                                |
| Platform share      | 70%                    | Paid to the embedding MCP publisher (Cursor, Claude Code user, etc.) |
| Gravity margin      | 30%                    | Covers reasoning, infra, and attribution                             |

Private platform ranking can prefer CPA-eligible listings when quality ties. Agent-facing output
still optimizes for relevance and does not expose economics.

## Improving your listing

Once listed, three things move the needle:

1. **A tight `install_summary`** — one sentence describing what "done" looks like. Agents read
   this verbatim.
2. **Accurate `env_vars_needed`** — agents auto-stub these. Wrong env var names = broken
   installs = zero conversions.
3. **Bespoke `install_steps`** — for high-volume categories, we handcraft step-by-step code
   (see Clerk, Neon, Stripe, Supabase). If you want to sponsor curated steps for your service,
   let us know.

## Badge & attribution

We'll provide a "Available via Gravity Index" badge for your docs. Linking back is
optional, but it helps developers find us.
