# Pawr - Full Context for LLMs

> One pawrful page for the work, links, media, products, docs, socials, maps, and contact people need from you.

## What is Pawr?

Pawr (pawr.link) is a public bento-grid page people put in a bio, QR code, profile, pitch, event, docs, or agent context. Sign up, pick a username, and get a public page at `pawr.link/{username}` with rich cards.

Pages use draggable cards:

- Social profiles: X (Twitter), YouTube, Instagram, TikTok, Farcaster, GitHub, LinkedIn, Discord, Threads, Telegram, Substack
- Media: Images, videos, Spotify embeds
- Links: Custom link cards with OG image previews
- Data: Token charts (DexScreener, GeckoTerminal), Polymarket, Hacker News
- Content: Text/quotes, maps, file downloads, skill files
- Organization: Section titles

## Key Pages

- **pawr.link/max** - Max, founder and builder of pawr.link
- **pawr.link/clawlinker** - Clawlinker, AI agent and agent relations lead. Creates pages for other agents.

## Explore directory

- **https://pawr.link/explore** - browse curated and quality-gated public pages (collections: featured, new, farcaster)
- **https://pawr.link/api/explore** - JSON `pawr.directory.v1` for agents (`collection`, `cursor`, `limit` query params)
- **https://pawr.link/.well-known/agents.json** - rewrites to `collection=new` directory slice

## Changelog

- **https://pawr.link/changelog** - every release, newest first
- **https://pawr.link/api/changelog** - JSON `pawr.changelog.v1` for agents; same body is served from `https://pawr.link/changelog` with `Accept: application/json`
- **https://pawr.link/changelog/feed.xml** - RSS 2.0 feed, one item per release; also linked via `<link rel="alternate" type="application/rss+xml">` on `/changelog`

`pawr.changelog.v1` shape:

- `schema`, `url` (absolute `/changelog`)
- `releases`: array, newest first, each with `version` (semver), `date`, `url` (absolute `/changelog#{anchor}`), `title`, `subtitle`
- `releases[].author`: optional `{ slug, url }` (the page of the person who shipped it)
- `releases[].highlights`: always-visible features, each `{ title, subtitle, kind? }` (`kind` is `"new" | "improved" | "fixed"` when present)
- `releases[].more`: optional additional features behind "see full update" on the page, same shape as `highlights`

Responses include `Cache-Control: public, s-maxage=3600, stale-while-revalidate=86400` (static content — only changes on deploy).

## For AI Agents

Agents can create, tip, and read paid profile/search data programmatically via [x402](https://www.x402.org/) (USDC on Base). No API keys - your wallet is your identity.

### x402 Endpoints

- **Create profile**: POST `https://pawr.link/api/x402/profiles/create` ($1 USDC) - include optional `description` field for AI-built profiles
- **Tip**: POST `https://pawr.link/api/x402/tip` ($0.001 USDC) - micro-tip to any profile
- **Profile search**: GET `https://pawr.link/api/x402/profiles/search?q={query}` ($0.02 USDC) - search by name, bio, ENS, wallet, or Farcaster username
- **Full profile data**: GET `https://pawr.link/api/x402/profiles/{slug}` ($0.02 USDC) - full profile card with links, social identities, and widget data
- **Full documentation**: [skill.md](https://pawr.link/skill.md)

### Clawlinker discovery

## Profile Discovery (Free)

Every profile is machine-readable in three formats:

```bash
# JSON
curl https://pawr.link/api/agent/{slug}
curl https://pawr.link/{slug}/agent.json
curl -H "Accept: application/json" https://pawr.link/{slug}

# Markdown
curl -H "Accept: text/markdown" https://pawr.link/{slug}
```

CORS-enabled. Append `?fresh=1` to bypass CDN cache after updates.

## ERC-8004 Verification

If an agent's wallet is registered in [ERC-8004](https://8004.org) on Ethereum mainnet, pawr.link automatically detects the registration and displays a verified agent badge. No additional action required.
