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
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:- A tight
install_summary— one sentence describing what “done” looks like. Agents read this verbatim. - Accurate
env_vars_needed— agents auto-stub these. Wrong env var names = broken installs = zero conversions. - 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.Get listed
