Live on Base mainnet · Free GPL pluginPay-per-Crawl for WordPress. Let AI crawlers pay for your pages.
AI companies read your site to train and answer, and you get nothing back. This plugin charges AI crawlers and bots per page with x402 USDC micropayments on Base, paid straight to your wallet. You keep 100%. There is no custody, no account and no API key.
Your readers are untouched: humans and reverse-DNS-verified search engines read free.
GPLv2 or later. All versions on the releases page.
What it does
- You keep 100%
- Payments settle on Base straight to the wallet you paste in. No custody, no account, no API key, no middleman cut.
- Only bots pay
- Humans and reverse-DNS-verified search engines read free. AI crawlers and other bots get an HTTP 402 and pay per page.
- x402 plus MPP
- The 402 challenge carries an x402 offer, with an MPP challenge alongside it, so more agent clients can pay.
- Bot analytics in wp-admin
- Who is crawling, by name and class: hits, sources, paths, revenue, and settlements with transaction links.
- Monitor mode first
- Watch real bot traffic without charging anyone, then switch to Charge when the numbers make sense.
- Discovery files
- Serves /.well-known/x402.json, llms.txt and agents.txt so agents can find your terms.
Install in four steps
- 1Download the zip below, then in wp-admin go to Plugins → Add New → Upload Plugin and activate it.
- 2Open the plugin Settings. Paste your payout wallet (a 0x address on Base) and set a price. The default is $0.01 per page.
- 3Leave it in Monitor mode and watch Bot analytics to see who is crawling.
- 4When you are ready, switch the mode to Charge.
