Roadmap

Now (0.1, preview)

• TypeScript verifier: RFC 9421, Web Bot Auth, Visa TAP, Verifiable Intent, AP2, Stripe token limits
• Hash-chained evidence ledger and evidence packs
• Express middleware, CLI, local playground, test vectors

Next

• Publish @provethebuy/verify and @provethebuy/cli to npm with signed provenance
• Next.js and edge-runtime middleware (WebCrypto only)
• Python and Go verifiers passing the same test vectors
• Postgres and SQLite ledgers
• A GitHub Action for agent builders: "does my agent sign correctly?"

Cloud

• Hosted ledger with 13-month retention and external anchoring
• Dashboard: the five screens
• Stripe App: dispute webhooks, automatic evidence submission
• Billing and plans

When the standards settle

• Visa TAP body-object signing, once issue #23 is answered
• AP2 user-key trust
• Verifiable Intent field names once Mastercard finalises them
