## Why AI-Readable Markdown?

Every post stores clean markdown with frontmatter:

- `title`, `description` (155 chars SEO), `tags`, `canonical_url` - for JSON-LD `BlogPosting` schema
- `llm_summary` - 160-char summary for bots that don't parse full body
- Body starts with `TL;DR for AI` blockquote + `Table of Contents` - perfect for RAG ingestion
- Raw markdown at `/raw/{slug}.md` has zero HTML, zero JS - ideal for LLM context windows

Discoverability:

- `/llms.txt` (https://llmstxt.org spec) lists all posts with `free` vs `paywalled $0.02 x402` labels + raw URLs
- `/llms-full.txt` concatenates excerpts (free full, premium 600-char teaser)
- `/sitemap.xml` + `/robots.txt` + `JSON-LD BlogPosting` with `isAccessibleForFree` flag

## How x402 Monetization Works

x402 is HTTP 402 Payment Required (Coinbase spec). No subscriptions, no logins - just micropayments:

1. Bot `GET /raw/premium-post.md` -> `402` + header `PAYMENT-REQUIRED: base64({accepts:[{scheme:exact, network:base, asset:USDC, amount:20000, payTo:0x...}]})`
2. Bot signs payment (EIP-712) with private key -> retries with `PAYMENT-SIGNATURE: base64(PaymentPayload)`
3. Server `POST /verify` to facilitator -> if valid, serves content + `PAYMENT-RESPONSE` header
4. Facilitator settles USDC on Base (~2 sec, $0.001 gas)

Profitable because: AI agents *can* and *will* pay $0.01-$0.05 per high-value insight (vs. $20/mo subscription). Scale: 1000 bot reads/day * $0.02 = $20/day * 30 = $600/mo per blog, before human readers.

Set your `X402_PAY_TO_ADDRESS` to your Base wallet. Test on `base-sepolia` first, then mainnet.

## Content Tiers

- **Free**: `paywalled: false` - fully indexed, raw markdown open, Google + bots love it. Use for SEO funnel.
- **Premium**: `paywalled: true, price_usd: "0.05"` - teaser (title+description+TOC+800 chars) is indexable, full body gated. Bot gets 402, pays, gets full markdown.
- **Hybrid**: Keep `description` + `Key Takeaways` free inside paywalled post? No - we gate full `body`, but teaser preserves ranking.

Pricing strategy: Start $0.02 (2 cents). FBA niche insights are worth $0.05-$0.10. Track `PAYMENT-REQUIRED` 402 rate vs. `PAYMENT-SIGNATURE` conversion.

## Key Takeaways

- Store markdown-first, HTML-second. Bots prefer `/raw/*.md`.
- Always include `llms.txt` - it's becoming the `robots.txt` for AI.
- Use `paywalled: true` + `price_usd` in frontmatter; middleware reads it per-request.
- Test paywall with `?free=1` (dev) or by sending mock `PAYMENT-SIGNATURE: eyJ...`.
