X402 Protocol · Stellar Blockchain

Let AI Agents Pay
for What They Use.

Verivyx is the infrastructure layer that monetizes AI agent access to content — while keeping the web frictionless for real humans. Powered by Stellar and the X402 Protocol.

The $100B Problem Nobody Is Solving

AI agents access and extract content at unprecedented scale — with zero compensation flowing back to the people who created it.

01 —
🤖

AI Scrapers Pay Nothing

Bots crawl and extract content at industrial scale. No CAPTCHA stops them long-term. No payment flows to creators. The economics of the open web are broken.

02 —
🔌

No Machine-Readable Payment Standard

AI agents have no interoperable protocol to autonomously discover and fulfill payment requirements. HTTP 402 exists but has never been implemented at scale.

03 —
🛡️

Humanity Checks Fail at Scale

CAPTCHAs frustrate real users while sophisticated bots solve them in milliseconds. Existing defenses are losing the arms race against AI-powered scrapers.

Verivyx is the X402 Native Infrastructure

One unified layer that serves humans seamlessly, charges AI agents automatically, and pays creators instantly.

For Humans

Zero Friction. Invisible Verification.

PoW + JA4 fingerprinting verifies real browsers silently in the background. Real users never see a CAPTCHA or delay.

  • Browser-native PoW challenge — 100–500ms human baseline
  • JA4 TLS fingerprinting — unfakeable network identity
  • Short-lived Session JWT, IP + browser bound
  • Content hydration with smooth UI transitions
For AI Agents

Autonomous Micropayments. Fully Programmatic.

HTTP 402 challenge → USDC micropayment on Stellar → instant content access. No human in the loop, ever.

  • X402 Protocol native — standardized HTTP 402 Payment Required
  • Stellar multi-op TX: creator + platform split in one atomic TX
  • 1-hour Redis session after a single payment (multi-request)
  • Idempotency keys — no double-charging on retries
For Creators

Set Your Price. Earn On Every Request.

Set your price, embed the 2KB script, and watch on-chain revenue accumulate. No manual withdrawals, no trust required.

  • Configurable price per AI agent request (any USDC amount)
  • Automatic on-chain revenue split — no manual step
  • Real-time analytics: GMV, bot activity, JA4 fingerprints
  • Drop-in paywall.min.js — no backend changes needed
// flow

Three Paths. One Infrastructure.

Every request is automatically classified and routed — human, paying agent, or blocked bot. No per-request configuration needed.

// architecture

Built for Scale. Built for Production.

Five purpose-built microservices. Go for performance-critical paths. Node.js for blockchain and ecosystem depth. No compromises.

Node.js / Prisma
auth-service
The Brain

Identity management, RBAC, API key issuance, Audit Logging, and analytics aggregation. Primary owner of PostgreSQL.

Go / Gin / Redis
x402-gateway
Payment Hub

High-throughput X402 protocol implementation. Redis-cached paid sessions. Testnet ↔ Mainnet orchestration at the edge.

Go / Gin
hydration-service
The Gatekeeper

Edge gatekeeper. Extracts JA4 fingerprints, monitors PoW timing, decides human vs bot in real-time on every request.

Node.js / Stellar SDK
payment-relayer
Blockchain Bridge

The only service touching Stellar Horizon & Soroban RPC. Validates XDR, verifies signatures, submits on-chain.

Vanilla JS · 2KB
embed-script
The Shield

Drop-in paywall.min.js. Web Worker PoW, browser fingerprinting, human/agent divergence. Zero framework dependency.

// defense_layers

Five Layers. All Must Fall Simultaneously.

Each layer is independently effective. Defeating all five at once is economically and technically impractical.

Layer Technology What it does
L1
JA4 TLS Fingerprinting
Client Hello → hash
Identifies bot clusters even when rotating IPs. The fingerprint is tied to the underlying SSL library — impossible to spoof without changing the entire network stack. Detects coordinated bot farms sharing the same JA4 signature across thousands of IPs.
JA4 TLS 1.3
L2
Proof of Work
SHA-256
CPU-intensive cost that makes high-frequency mass scraping economically unviable. Humans naturally solve in 100–500ms. Any response under 50ms is flagged as a speed anomaly and classified as a bot — regardless of other signals.
PoW <50ms = bot
L3
X-Internal-Token Mesh
Zero-trust service auth
No microservice accepts a request from another without a shared INTERNAL_TOKEN header. External actors cannot call internal APIs regardless of network access. Service-to-service calls are verified at every hop.
Zero-Trust
L4
Soroban USDC Auth
On-chain multi-op TX
Forces AI agents to commit real economic stake per access. Every content request requires a verified on-chain USDC micropayment. No payment = no access. Financial cost makes automated mass extraction economically self-defeating.
USDC Soroban
L5
Idempotency Keys
UUID v4 · Redis dedup
UUID-based double-payment prevention stored in Redis. Agents can safely retry failed requests without risk of being double-charged. Every transaction has a unique key verified before settlement is accepted.
UUID v4 Redis

Revenue That Works For Everyone

Automatic on-chain revenue split in a single atomic transaction. No trust required — mathematics enforces fairness.

Creator Revenue Platform Fee
~95% → Creator Wallet 5% → Platform
Creator Revenue
Price − Platform Fee, paid directly to creator's Stellar wallet on-chain in the same TX
Platform Fee
5% platform fee per request, paid to platform Stellar wallet in the same multi-op TX
// platform_fee
5%
Platform fee per AI agent request. Predictable and transparent. Creators keep 95% of every payment — flowing directly to their Stellar wallet.
// creator_price
Configurable
Creators set their own price per request. Any amount above the platform fee flows directly to their Stellar wallet with no manual step.
// settlement_model
Atomic
One Stellar transaction, two payment operations. Creator and platform receive funds simultaneously — partial settlements are structurally impossible.
