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

Agent-native distribution

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”.

Install instructions included

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.

CPA billing — only pay on results

No CPC, no CPM. You define a cost per successful signup and pay only after a confirmed conversion or completed integration.

Referral revenue for platforms

Platforms embedding the Index (like Cursor) earn 70% of the CPA. You acquire the user. Everyone’s aligned.

How it works

1. 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.

2. 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.

3. 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.

4. 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.

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.
