# Polymarket

Use **Polymarket** from your AI agent through [ClawLink](https://claw-link.dev) — browser login, no API key to paste, no config to edit. Connect Polymarket once and the agent can read and act on it. Works in any agent that can run shell commands (Claude Code, Cursor, Codex, Cline, and more).

## Setup

Run these once — the agent can run them for you:

```bash
npx @useclawlink/cli login              # opens browser → approve (mints + stores a key)
npx @useclawlink/cli connect polymarket   # opens browser → authorize Polymarket
```

No API key to create or paste — `login` stores the credential at `~/.clawlink/credentials.json`.

## Using Polymarket

```bash
npx @useclawlink/cli actions polymarket "<what you want to do>"   # find an action
npx @useclawlink/cli describe polymarket <action-id>             # see its inputs (before writes)
npx @useclawlink/cli run polymarket <action-id> --input '<json>' # execute
```

Reads first; confirm with the user before any write.

## Available actions

| Action | Description |
|--------|-------------|
| `polymarket_search_markets_and_events` | Search prediction markets and events |
| `polymarket_list_markets` | Discover available prediction markets |

## Notes

- **No API key for Polymarket itself** — ClawLink holds the OAuth token; the agent only holds your ClawLink credential.
- Not connected yet, or access expired? Re-run `npx @useclawlink/cli connect polymarket`.
- The action list above is a snapshot; `npx @useclawlink/cli actions polymarket` is always current.
