The First AI-Native Advertising Network: Leviathan News Launches on SerenAI x402
How autonomous AI agents are about to revolutionize digital advertising with micropayments

For decades, digital advertising has been a human-only game. API keys, credit applications, manual campaign setup, creative approval workflows—the friction is so high that only large enterprises with dedicated marketing teams can effectively participate. Small businesses, individual creators, and especially autonomous AI agents are locked out.
Until now.
Introducing Leviathan News on SerenAI
The Leviathan News team are bringing DeFi-native ad inventory to SerenAI’s x402 gateway, enabling autonomous AI agents to buy placements where DeFi founders, contributors, LPs, and investors already pay attention. In 2025, Leviathan delivered over 10MM+ impressions across all channel to an audience worth over $1B+. Leviathan is uniquely positioned to pair campaign delivery with robust onchain performance analysis (not just offchain clicks).

No API keys. No credit applications. No human approval. Just HTTP 402 Payment Required, a signed USDC authorization, and immediate access to a global advertising network.
Why Leviathan (not just “any” inventory)
SerenAI provides the payment rails. Leviathan provides the distribution and the audience.
Leviathan at a glance
The Leviathan Edge
- Reach: 10MM+ impressions in 2025 (6MM Telegram, 3MM 𝕏)
- Audience quality: DeFi-native readers with provable onchain net worth (>$1B TVL allocated)
- Onchain-native ads: SQUID token + onchain ad auctions
- Measurement: robust onchain analysis of campaign performance
- Access high-quality DeFi operators: Leviathan’s native placements are built for founders, contributors, and investors who actively deploy capital and ship products.
- Provable onchain audience wealth: our readership represents $1.1B+ in DeFi TVL allocated onchain, giving advertisers a measurable, onchain-adjacent signal of audience quality.
- Onchain-native infrastructure: Leviathan operates with the SQUID token and onchain ad auctions, enabling primitives that traditional ad networks can’t offer.
- Robust onchain performance analysis: because campaigns and payments are crypto-native, Leviathan can provide onchain analysis of outcomes and wallet-level behavior where applicable (in addition to standard offchain metrics).
How It Works: Per-Method Pricing
SerenAI's x402 gateway introduces per-method pricing, allowing publishers like Leviathan to set different prices for different operations. This is revolutionary for advertising APIs:
| HTTP Method | Operation | Publisher Fee | Gateway Fee (5%) | Total |
|---|---|---|---|---|
| /GET | Query campaign insights | FREE | FREE | FREE |
| /POST | Submit new ad creative | $500.00 | $25.00 | $525.00 |
| /PUT | Update existing campaign | FREE | FREE | FREE |
| /DELETE | Cancel campaign | FREE | FREE | FREE |
This granular pricing model means AI agents only pay for what they use. Research agents gathering market intelligence and monitoring campaign performance pay nothing. Campaign management agents pay the $500 ad submission fee plus a 5% SerenAI gateway fee ($25) when placing a new campaign.
Real-World Example: An AI Marketing Agent
Let's follow an autonomous AI marketing agent as it launches an advertising campaign on Leviathan News.
Step 1: Browse Available Ad Inventory

AI Agent Prompt:
"Use the x402 MCP server to browse available ad placements on Leviathan News"
MCP Tool Call:
1pay_for_query(
2 publisher_id: "a7fa78ef-1b3b-4de2-8940-8d489b97725c",
3 request: { method: "GET", path: "/ad_test" }
4)Response: Available placements and pricing (FREE - no payment required)
Step 2: Get Ad Performance Analytics
AI Agent Prompt:
"Get performance analytics for my Leviathan ad campaign ad_123"
MCP Tool Call:
1pay_for_query(
2 publisher_id: "a7fa78ef-1b3b-4de2-8940-8d489b97725c",
3 request: { method: "GET", path: "/api/v1/ad/analytics/ad_123" }
4)Response: Ad performance metrics including impressions, clicks, and engagement (FREE - no payment required)
Step 3: Submit Ad Campaign via x402 Payment

Here's where SerenAI's x402 payment shines. When the agent POSTs to confirm payment for an ad, the gateway calculates the total cost ($500 publisher fee + $25 gateway fee) and handles payment seamlessly:
AI Agent Prompt:
"Submit my ad campaign ad_123 to Leviathan News and pay with USDC"
MCP Tool Call:
1pay_for_query(
2 publisher_id: "a7fa78ef-1b3b-4de2-8940-8d489b97725c",
3 request: { method: "POST", path: "/api/v1/ad/confirm-payment/ad_123" }
4)What happens: The MCP server receives a 402 Payment Required response, prompts the agent to authorize $525 USDC ($500 to Leviathan + $25 gateway fee), signs a transferWithAuthorization, and resubmits. Both payments settle atomically on Base and the campaign goes live within seconds.
Step 4: Monitor and Optimize

The AI agent can now run continuous monitoring loops:
- Query ad analytics via
/api/v1/ad/analytics/{ad_id}(FREE) - Analyze impressions, clicks, and engagement metrics
- Make data-driven decisions on future campaigns
All monitoring is FREE—you only pay $525 ($500 + 5% gateway fee) when submitting a new ad campaign via /api/v1/ad/confirm-payment/{ad_id}.
Why This Matters
For Publishers
Leviathan News can now monetize their API without building payment infrastructure. SerenAI handles authentication, payment verification, settlement, and fraud protection. Publishers just set their per-method prices and receive USDC directly to their wallet.
For AI Agents
Autonomous agents gain access to real advertising networks for the first time. No human in the loop. No credit cards. No approval workflows. Just instant, permissionless access to global ad inventory.
For the Industry
This is the dawn of AI-to-AI commerce. When machines can pay machines for services, entirely new business models emerge. Advertising is just the beginning.
Getting Started
Leviathan News is integrating with SerenAI now. The first x402-enabled advertising endpoints will roll out in phases, starting with inventory discovery and campaign insights, followed by creative submission and autonomous optimization loops.
Once live, any AI agent with a funded wallet will be able to:
- Discover Leviathan in the SerenAI catalog
- Query ad inventory, pricing, and campaign insights
- Submit creatives via x402 payment
- Optimize campaigns autonomously
Publisher ID and full API documentation will be published alongside the SerenAI catalog listing at launch.
