What you get / detection, pricing, settlement

Bot detection

GPTBot, ClaudeBot, PerplexityBot, and pattern-based agents, caught by user-agent and request signals. Humans pass straight through.

Per-path pricing

Homepage free, /api/premium at $0.001, /research/* at $0.01. Price each path on its own, in pay.json or the dashboard.

Non-custodial

The agent pays your wallet directly. Xenarch verifies the payment on-chain and never holds, signs for, or touches funds.

Open standard

Machine-readable pricing at /.well-known/pay.json. Agents read the cost before they ask. Open spec, no lock-in.

Questions

how it works
Install Xenarch middleware (WordPress, FastAPI, or Cloudflare Worker). An agent requests a gated page → the server returns HTTP 402 with the price → the agent signs a USDC payment → middleware verifies on-chain → content is served. Payment goes agent wallet → your wallet, 0% Xenarch fee.
vs Cloudflare PPC
Cloudflare PPC only works behind Cloudflare’s CDN, is custodial, and takes a cut. Xenarch works on any host, is non-custodial, and takes 0%.
vs TollBit
TollBit serves enterprise publishers via manual licensing and fiat invoicing, so the minimum viable publisher is millions of visitors. Xenarch is self-serve and works for the 50K-visitor blog, settling per request in USDC.
per-path pricing
Yes. Homepage free, /api/premium-data at $0.001, /research/* at $0.01. Configure via pay.json or the dashboard; each URL priced independently.
pay.json
Open standard for machine-readable pricing at /.well-known/pay.json, robots.txt for payments. Agents read it to discover costs before requesting. Open spec.
network
USDC on Base mainnet, chain 8453. Direct wallet-to-wallet settlement, verifiable on Basescan.
