x402 protocol · Stellar Soroban

Charge AI agents per request.
Let humans browse free.

Verivyx sits in front of your content. It tells humans from agents, hides text from scrapers, and forces every AI request to settle a USDC micropayment over Stellar before it sees a single token.

Watch an AI agent pay for content in real time.

The Verivyx Playground hands a sandboxed agent a funded testnet wallet. Ask it to open a paywalled page — it hits a 402, settles USDC over x402 on Stellar, and unlocks the content, every step on-chain and visible. Or tell it to access without paying and watch the paywall block it cold.

How it works

One script. Three layers between bots and your bytes.

01

Detect

Embedded heuristics inspect WebGL, mouse motion, navigator fingerprints, and known agent UAs. Humans never notice.

02

Hydrate

Real text never lands in HTML for unverified sessions. Hydration service serves a 402 to bots and decrypted content to humans.

03

Settle

Agents that want access pay USDC on Stellar. The x402 facilitator verifies the txn against Horizon, then unlocks for 1h.

WP

Running WordPress? Skip the code.

Install the Verivyx Paywall plugin and hit activate — zero config. It auto-detects your domain and starts charging agents. Humans read free, just like the script tag.

Built for the agentic web

The infrastructure layer for AI revenue.

We're not robots.txt. We don't block agents — we charge them. Real-time settlement, on-chain auditability, and zero impact on organic readers.

Sub-second 402s

Edge detection in <50ms via the embed script. No round-trip to your origin until the agent pays.

Stellar Soroban native

USDC micropayments settle in ~5 seconds with sub-cent fees. The paywall_core contract splits creator + platform on-chain.

Per-domain pricing

Set a different price per request for each property you operate. Update it from the dashboard live.

Know Your Agent

See which AI labs are reading your archive, in real time. Deep research vs. RAG vs. training.

No mocks. Real verification.

Every payment is verified on Stellar (Horizon for classic, Soroban RPC for spec) before unlocking. No trust-the-client shortcuts.

Human-friendly

Real users see no challenges, no captchas, no flickers. Just your content.

Pricing

Free to deploy. A flat fee per settled request.

You set the price an agent pays. A small fixed platform fee comes out of each settled payment — you keep the rest. No subscriptions, no minimums. You only earn when an agent pays you.

The other side of x402 · early access

Built for the agents that pay you.

Verivyx is two-sided. Creators get paid through the paywall — and with the Verivyx x402 MCP, any AI agent can pay for any x402 resource across Stellar, Base, and Solana, non-custodially, from a single connection. One flat $0.001 fee per payment.

Coming soon

Verivyx MCP Server

A first-party Model Context Protocol server so agents like Claude can discover Verivyx-protected resources and settle payments natively — no glue code.

Coming soon

Developer SDK

A drop-in TypeScript SDK to add x402 payments to your own agent in a few lines — handle the 402, sign the USDC transfer, retry, done.
