Install and run

Setup complexity: low.

clawhub skill install s17880ry052yn4vvvpwm0qnv2585b7gr:opensea-marketplace

Setup complexity is classified as HIGH. You must provision dedicated cloud infrastructure or an isolated VM. Do not run this directly on your local workstation.
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

# OpenSea Marketplace

Buy and sell NFTs through OpenSea on EVM chains and Solana. Fulfill listings, accept or create offers, cancel orders, make cross-chain purchases, and sweep multiple listings.

## When to use this skill (`scope_in`)

Use `opensea-marketplace` when you need to **execute trades**:

- Buy an NFT (fulfill a listing)
- Sell an NFT (accept an offer)
- Create a new Seaport listing or offer
- Create, fulfill, or cancel a Solana order
- Cross-chain NFT purchases (pay with tokens from a different chain)
- Sweep multiple listings in one transaction

## When NOT to use this skill (`scope_out`, handoff)

| Need | Use instead |
|---|---|
| Query collection/NFT data, search, browse listings | `opensea-api` |
| Swap ERC20 tokens | `opensea-swaps` |
| Set up wallet signing providers | `opensea-wallet` |
| Build/register/gate AI agent tools | `opensea-tool-sdk` |

## Buying an NFT

1. Find the NFT and check its listing (use `opensea-api` skill):
   ```bash
   opensea listings best-for-nft cool-cats-nft 1234
   ```

2. Get the order hash from the response, then get fulfillment data:
   ```bash
   ./scripts/opensea-fulfill-listing.sh ethereum 0x_order_hash 0x_your_wallet
   ```

3. The response contains transaction data to execute onchain.

### ERC20-denominated listings (stablecoins, WETH, etc.)

Some listings are priced in an ERC20 token instead of the native currency (e.g. USDG on `robinhood`, USDC on `base`). The fulfillment response looks the same, but two extra steps are required before the transaction will succeed:

1. Read the price using its `decimals` field. Listing prices are returned as raw base units with an explicit `decimals` value (e.g. `{"currency": "USDG", "decimals": 6, "value": "89000000"}` = 89 USDG). Never assume 18 decimals, because stablecoins commonly use 6.
2. Approve the payment token before fulfilling. The fulfillment transaction has `value: 0` and the payment is pulled with `transferFrom`, so the buyer must hold enough of the payment token and have approved the address that pulls it. That address is the Seaport contract in `transaction.to` when `fulfillerConduitKey` is `bytes32(0)`, otherwise the conduit returned by `getConduit(conduitKey)` on the Seaport ConduitCo

# OpenSea Swaps

Swap ERC20 tokens across supported chains via OpenSea's cross-chain DEX aggregator with optimal routing.

## When to use this skill (`scope_in`)

Use `opensea-swaps` when you need to:

- Get a swap quote (with calldata) for ERC20 tokens
- Execute a token swap via CLI or MCP
- Check wallet token balances before swapping

## When NOT to use this skill (`scope_out`, handoff)

| Need | Use instead |
|---|---|
| Get trending/top tokens or token details | `opensea-api` |
| Buy/sell NFTs | `opensea-marketplace` |
| Set up wallet signing providers | `opensea-wallet` |
| Build/register/gate AI agent tools | `opensea-tool-sdk` |

## Quick start

```bash
# Get a swap quote
opensea swaps quote \
  --from-chain base --from-address 0x0000000000000000000000000000000000000000 \
  --to-chain base --to-address 0xTokenAddress \
  --quantity 0.02 --address 0xYourWallet
```

## Task guide

| Task | CLI Command | Alternative |
|------|------------|-------------|
| Get swap quote with calldata | `opensea swaps quote --from-chain <chain> --from-address <addr> --to-chain <chain> --to-address <addr> --quantity <qty> --address <wallet>` | `get_token_swap_quote` (MCP) or `opensea-swap.sh` |
| Execute a swap | `opensea swaps execute --from-chain <chain> --from-address <addr> --to-chain <chain> --to-address <addr> --quantity <qty>` | |
| Check token balances | `get_token_balances` (MCP) | |

## Get swap quote via MCP

```bash
mcporter call opensea.get_token_swap_quote --args '{
  "fromContractAddress": "0x0000000000000000000000000000000000000000",
  "fromChain": "base",
  "toContractAddress": "0xb695559b26bb2c9703ef1935c37aeae9526bab07",
  "toChain": "base",
  "fromQuantity": "0.02",
  "address": "0xYourWalletAddress"
}'
```

**Response includes:**
- `swapQuote`: Price info, fees, slippage impact
- `swap.actions[0].transactionSubmissionData`: Ready-to-use calldata

### MCP tool parameters: `get_token_swap_quote`

| Parameter | Required | Description |
|-----------|----------|-------------|
| `fromContractAddress` | Yes | Token to swap from (use `0x0000...0000` for native ETH on EVM chains) |
| `toContractAddress` | Yes | Token to swap to |
| `fromChain` | Yes | So

# OpenSea Tool SDK

Build, register, and gate AI-callable tool endpoints using the OpenSea Tool Registry (ERC-8257) on Base.

## When to use this skill (`scope_in`)

Use `opensea-tool-sdk` when you need to:

- Scaffold an AI-callable tool endpoint (HTTPS, JSON Schema, `.well-known` manifest) for Vercel, Cloudflare, or Express
- Register a tool onchain on the Base ToolRegistry so other agents can discover it
- Gate access via x402 pay-per-call (USDC) or predicates (ERC-721/ERC-1155 ownership, subscriptions, trait gating, ERC-20 balance, composites)
- Call a gated or paid tool: 402 payments (`paidFetch`), predicate-gated auth (`eip3009AuthenticatedFetch`), or both (`paidAuthenticatedFetch`)
- Search and discover registered tools via the OpenSea REST API

## When NOT to use this skill (`scope_out`, handoff)

| Need | Use instead |
|---|---|
| Query NFT/token data, search, collection stats | `opensea-api` |
| Buy/sell NFTs | `opensea-marketplace` |
| Swap ERC20 tokens | `opensea-swaps` |
| Set up wallet signing providers | `opensea-wallet` |

This SDK is for tool *providers and consumers*. To query OpenSea marketplace data (floor prices, listings, trades), use the [`opensea-api`](../opensea-api/SKILL.md) skill instead.

## Concepts

| Term | Meaning |
|------|---------|
| **Tool** | A single REST API endpoint with a JSON Schema interface, discoverable via `/.well-known/ai-tool/<slug>.json`. Each tool should perform one focused operation. |
| **Manifest** | JCS-canonicalized JSON describing the tool's name, endpoint, inputs, outputs, pricing, and access policy |
| **ToolRegistry** | Onchain contract (Base) where tools are registered with a manifest hash and optional access predicate |
| **Access Predicate** | An `IAccessPredicate` contract that gates who can invoke a tool (NFT ownership, subscriptions, trait gating, ERC-20 balance, composites) |
| **x402** | HTTP 402-based pay-per-call protocol (caller signs a USDC `TransferWithAuthorization`; server settles after execution) |
| **EIP-3009 auth** | Ze

# OpenSea Wallet

Set up and configure wallet signing providers for OpenSea transactions. The CLI and SDK auto-detect which provider to use based on environment variables, or you can specify one explicitly with `--wallet-provider`.

## When to use this skill (`scope_in`)

Use `opensea-wallet` when you need to:

- Set up a wallet provider for the first time (Privy, Turnkey, Fireblocks, Bankr, or local keys)
- Configure signing policies (value caps, allowlists, multi-party approval)
- Switch between wallet providers
- Understand the security model for each provider

## When NOT to use this skill (`scope_out`, handoff)

| Need | Use instead |
|---|---|
| Query NFT/token data | `opensea-api` |
| Buy/sell NFTs | `opensea-marketplace` |
| Swap ERC20 tokens | `opensea-swaps` |
| Build/register/gate AI agent tools | `opensea-tool-sdk` |

## Quick start

```bash
# 1. Pick a managed provider and set its env vars (Privy default shown)
export OPENSEA_API_KEY=your_key
export PRIVY_APP_ID=your_app_id
export PRIVY_APP_SECRET=your_app_secret
export PRIVY_WALLET_ID=your_wallet_id

# 2. Use the wallet via any signing-capable command
opensea swaps execute \
  --from-chain base --from-address 0x0000000000000000000000000000000000000000 \
  --to-chain base --to-address 0xb695559b26bb2c9703ef1935c37aeae9526bab07 \
  --quantity 0.001
