opensea-skill

opensea-api

Query OpenSea marketplace data via the official CLI, MCP server, or shell scripts. Get floor prices, collection stats, NFT details, token data, trending collections, drops, events, and search across Ethereum, Base, Arbitrum, Polygon, and more. Read-only operations; for trading use opensea-marketplace, for token swaps use opensea-swaps.

opensea

Query NFT and token data, trade NFTs on Seaport, swap ERC20 tokens via DEX aggregator, configure wallet signing providers, and build/register/gate AI agent tools on Base. Covers the full OpenSea developer surface across CLI, MCP server, shell scripts, and SDK. Pick the right sub-skill using the routing table below, then read that sub-skill's SKILL.md for operational detail.

alchemy-api

Wire Alchemy into application code using a standard API key. Covers EVM JSON-RPC, Token API, Transfers API, Prices API, Portfolio API, Simulation, Webhooks, Solana RPC/DAS/Yellowstone gRPC, Sui gRPC, Wallets/Account Kit. For NFT marketplace data, listings, offers, or Seaport fulfillment, use `opensea-api` / `opensea-marketplace`. For live agent work, use `alchemy-cli` or `alchemy-mcp`. For app code without an API key, use `alchemy-agentic-gateway`.

alchemy-mcp

Use the Alchemy MCP server (`https://mcp.alchemy.com/mcp`) for live blockchain data and admin work — 159 tools across 100+ chains for token prices, transactions, simulation, tracing, account abstraction, Solana DAS. For NFT marketplace data, listings, or Seaport fulfillment, use `opensea-api` / `opensea-marketplace`. For shipped app code, use `alchemy-api` (with API key) or `alchemy-agentic-gateway` (without). When the CLI is installed locally, prefer `alchemy-cli`.

opensea-marketplace

Buy and sell NFTs on OpenSea's Seaport marketplace. Fulfill listings, accept offers, create new orders, cross-chain purchases, and sweep multiple listings. Requires wallet signing; for read-only queries use opensea-api instead.

opensea-swaps

Swap ERC20 tokens across supported chains via OpenSea's cross-chain DEX aggregator. Get quotes with optimal routing, check token balances, and execute swaps. For NFT trading use opensea-marketplace, for querying token data use opensea-api.

alchemy-agentic-gateway

Wire Alchemy into app code without an API key — via x402 or MPP gateway with wallet-based auth (SIWE/SIWS) and per-request payments (USDC via x402, or USDC/credit-card via MPP). Specialized for autonomous agents that pay for themselves. For NFT marketplace data, listings, offers, or fulfillment, use `opensea-api` / `opensea-marketplace`. For app code with an API key, use `alchemy-api`. For live agent work, use `alchemy-cli` or `alchemy-mcp`.

alchemy-cli

Use the Alchemy CLI (`@alchemy/cli`) for live blockchain queries, admin, and on-machine automation across EVM JSON-RPC, Token, Transfers, Prices, Portfolio, Simulation, Solana RPC/DAS/gRPC, Sui gRPC, Webhooks, and app management. Preferred runtime path when CLI is installed locally. For NFT marketplace data, listings, or Seaport fulfillment, use `opensea-api` / `opensea-marketplace`. For shipped app code, use `alchemy-api` (with API key) or `alchemy-agentic-gateway` (without).

opensea-tool-sdk

Build, register, and gate AI-callable tool endpoints using the OpenSea Tool Registry (ERC-8257) on Base. Scaffold HTTPS tools with JSON Schema interfaces, register them onchain, gate access via NFT ownership or x402 pay-per-call (USDC), and call gated tools. For querying OpenSea marketplace data use opensea-api instead.

opensea-wallet

Set up and configure wallet signing providers for OpenSea transactions. Supports Privy, Turnkey, Fireblocks, Bankr, and local private keys. Required for executing trades (opensea-marketplace) and token swaps (opensea-swaps).
