What every edition shares

Same behaviour everywhere

One crawler catalog, one 402 shape, the same classifier. Humans and reverse-DNS-verified search engines read free; AI crawlers and bots pay per page.

You keep 100%

Each edition calls the facilitator itself: verify, then settle, then serve only on a transaction hash. Nothing routes through ForgeMesh.

x402 v1 + v2 and MPP

Every 402 carries a PAYMENT-REQUIRED v2 header, a v1 JSON body and a WWW-Authenticate: Payment challenge, so more agent clients can pay.

Discovery files

Each edition serves /.well-known/x402.json, llms.txt and agents.txt so agents can find your terms.

Proven with real money

Every edition was verified with two live $0.01 settlements on Base mainnet, one per protocol version, before release.

Optional Pro reporter

Point any edition at Pro for a hosted dashboard, Monday digest and paywall monitoring. Pro sees per-bot counts and settlements only.

Security notes

Two hardening fixes shipped across all editions on 17 October 2026 and are in every version listed above: trusted X-Forwarded-For now uses the right-most hop, so a client cannot prepend a search-engine IP to read free, and path exemptions are anchored to exact files or slash-delimited prefixes, so a crafted path cannot match an allow rule.
