2026-09-03Findable by crawlers, answer engines, and agents

A changelog at /changelog with an Atom feed at /changelog.atom, so every release is new content a crawler can read.
The status page now shows a public ledger: purchases settled and webhooks delivered in the last 30 days, uptime, and visits by AI crawler family.
robots.txt invites AI search and answer engines explicitly and points at a real sitemap; an IndexNow key file lets Bing, Yandex, Naver, and Seznam be told about changes directly.
/.well-known/x402.json mirrors the payment manifest under the name catalogs probe, and /.well-known/agent-tools.json describes the service for agent tool directories.
A visible questions section on the landing page, and structured data naming every product and price.

All six paid routes are listed in the CDP x402 Bazaar after their first settled payments.
Browser based x402 clients can now pay: the API allows the PAYMENT-SIGNATURE header and exposes the 402 and receipt headers.
The Solana receiving address gained its USDC token account; USDC payments on Solana settle.

POST /v1/wake ($0.01) calls your webhook at a time you set, up to 30 days ahead, with a payload you stored.
POST /v1/inbox ($0.10) issues a capture URL that holds anything POSTed to it for up to 7 days and forwards it to you.
Purchases are idempotent in front of the paywall: a retry with the same Idempotency-Key never charges twice.
Every paid route publishes an example request and schema for the Bazaar catalog.

Payments settle on Base and Solana through the Coinbase CDP facilitator with PayAI as fallback, in priority order set by FACILITATORS.
Paid routes opt into Bazaar discovery.

Designed pages for the human-facing links: /manual, /status, and the crawler policy at /bot.
A watch is voided if its payment never settles, so nothing is ever delivered unpaid.
