Gravity ad network

What it is and where ads appear

What it is

An ad network for AI: brands reach people inside conversations with LLMs, agents, chatbots and AI search, and the host apps earn from the ads.[1]

Where ads appear

Chat apps, coding assistants and IDEs, consumer AI apps and AI search. Gravity names no specific publisher apps.[2]

Publisher verification

Ads show only on websites and apps Gravity has verified; Gravity reviews each platform before real ads serve.[3]

Ad exclusivity on screen

When a Gravity ad is on screen, no other ad (other networks or house ads) can be on screen.[3]

Network size (self-reported)

Gravity claims 20+ AI platforms and 1B+ users across the network.[4]

Formats and creative

Ad formats (as served to AI platforms)

Text, server-rendered design, image (top/side), rich frame (iframe, web only), carousel (3-10 product cards, web only).[5]

Ad group types

Generative (Gravity writes the ad per conversation from your context) or Static/manual (shown exactly as written).[6]

Editing generated ads

Generated ads can't be changed; only manual ads can be edited or archived.[7]

Image requirements

Public PNG, JPEG, GIF or WebP, 10 MB or less; some delivery networks need an image on each ad.[7]

Buying model, objectives and budgets

Buying / pricing model

CPM (per 1,000 impressions), or CPA where the account allows it. No click (CPC) billing for new campaigns.[2]

Click billing

Not offered; billing_model cpm (cpc accepted only for older campaigns).[8]

Objective: Clicks

Optimizes for clicks; billed per 1,000 impressions (CPM); no tracking needed.[6]

Objective: Reach

Optimizes for unique people at lowest CPM; billed CPM; available to everyone.[6]

Objective: Conversions

Optimizes for a chosen conversion event; billed CPM; event must have server-side proof (live CAPI/integration event or passed CAPI test). Pixel events don't count.[6]

Objective: CPA eligibility

Pay per attributed conversion; requires $5,000 lifetime spend or Gravity unlock.[6]

Daily budget

Average daily budget in dollars; spend on one UTC day can reach 110%, then serving stops until the next day.[6]

Total (lifetime) budget

budget_type total requires total_budget, end_time and OpenAI-only delivery.[8]

Monthly cap (CPA)

CPA campaigns use a monthly cap; serving stops when spend reaches it each calendar month.[6]

Learning period

2 to 3 months for Conversions campaigns, up to 30 days for other objectives.[6]

Minimum spend

Minimum spend

No minimum; start with any daily budget. A payment method is required before a campaign can launch.[9]

Matching and targeting

How ads are matched

Contextual: the engine compares recent conversation messages with active campaigns, runs an auction and returns the winning ad.[10]

Country targeting

Countries chosen at campaign/ad-group level; none selected means all countries. Regions and DMAs via geo_targets.[6]

Countries (marketing claim)

Advertisers page shows "180+ countries".[11]

Device targeting

iPhone, Android or desktop (API: web, ios_app, android_app); none selected means all.[6]

English-only option

english_only serves only in conversations detected as English.[8]

Review and policies

Review process

Gravity reviews every new campaign before delivery; status shows Processing during setup; re-activation can trigger review again.[12]

Re-review on activation

Activation can send a campaign to review again.[13]

Restricted categories

Weapons, pharma, alcohol, tobacco/nicotine, digital assets, political, dating and licensed gambling need explicit Gravity authorization; a separate prohibited list applies.[14]

Reporting limits

Reporting levels

Daily metrics at campaign, ad group and ad unit (creative) level.[15]

Creative-level reporting limits

Ad-unit reports give impressions, clicks, spend, CTR, CPC, CPM; conversions, CPA and ROAS are attributed only at campaign level.[15]

Attribution window

Currently 7 days after a Gravity click or view; may change.[15]

Report lookback

1 to 365 days per request.[15]

Disclosure

Disclosure label

All formats carry a "Sponsored" label.[5]

Labelling policy

All advertising must be identified as such per FTC native-advertising guidance.[14]

API and MCP

API base URL and auth

REST API at https://platform.trygravity.com, X-API-Key header on every request.[13]

API key scope

One key per account, no scopes, full access including spend.[16]

API rate limit

About 100 requests per second per client IP; 429 with Retry-After above that.[16]

Default campaign status on create

active (draft and paused also allowed); docs warn active campaigns can spend.[8]

Delivery network mode

network_mode: dynamic, gravity or openai; OpenAI-only delivery needs account access.[8]

Dashboard MCP server

https://platform.trygravity.com/mcp; same API key; full admin access; actions run without confirmation; no spend limit.[17]

Partner delivery (OpenAI / ChatGPT)

Campaigns can deliver on partner networks; reporting for ChatGPT and OpenAI campaigns aligns with OpenAI reports (America/New_York).[13]

Where sources disagree

When Gravity’s own pages disagree, both are shown. We don’t pick one.

Ad formats (FAQ version)

sources disagree FAQ lists Sponsored Block and Inline Hyperlink[9]Gravity’s FAQ lists two formats, Sponsored Block and Inline Hyperlink. Its docs list five: text, server-rendered design, image, rich frame and carousel.

Attribution (FAQ version)

sources disagree FAQ says click-based attribution[9]Gravity’s FAQ calls attribution click-based. Its reporting docs count conversions within 7 days of a Gravity click or view.

Keyword targeting

sources disagree Advertisers page offers keyword targeting; docs say matching is on context, not keywords, and the campaign API rejects a `keywords` field.[11]Gravity’s advertisers page mentions keyword targeting. Its docs say it matches on context, not keywords, and its campaign API rejects a keywords field.

How Admux buys it

Admux sells this channel as Gravity network. This is what Admux does on your behalf; it doesn’t change what Gravity allows.

1. Admux buys Gravity with manual (static) ads you write. Gravity’s generative ad groups write the ad for you and can’t be edited, so Admux doesn’t use them.
2. Campaigns are created as drafts and launched only after Gravity’s review and your go-ahead. This matters because Gravity’s API creates campaigns as active by default.
3. Gravity’s API key has full account access and no scopes. Admux keeps it server-side and gives your agent its own scoped key with a spending limit.
4. Your full budget is reserved from your prepaid balance before submission, so delivery can’t draw on money you didn’t set aside.
