Marketplace data at your fingertips

Your AI agent navigates OpenSea's NFT marketplace programmatically, pulling collection details, listings, offers, and event histories into every conversation about digital assets.

Browse Collections

A community member asks about trending NFT collections. Your AI agent queries OpenSea for collections filtered by chain, creator, or sort order, returning names, floor prices, and volume traded. Market research happens in conversation, not on a separate tab.

Check Collection Stats

A trader asks for the floor price and total volume of a specific collection. The agent retrieves real-time stats from OpenSea including floor price, total sales, number of owners, and average price. Market intel delivered in seconds during the chat.

View NFT Details

A collector wants to know about a specific NFT's traits, rarity, and ownership. The agent fetches metadata for the token from OpenSea, including all traits, the current owner's address, and rarity information. Due diligence happens right in the conversation.

List Active Offers

A seller asks what offers exist on their collection. The agent retrieves all active, valid offers from OpenSea for that collection slug, showing offer amounts, expiration times, and offerer addresses. Sellers make informed decisions without checking the OpenSea app.

Track Marketplace Events

A community manager needs recent sales activity. The agent pulls events from OpenSea filtered by type and time range, showing sales, transfers, and listing creations. Activity monitoring becomes a simple question in your community chat.

Get Best Listing Price

A buyer asks for the cheapest available NFT in a collection. The agent queries OpenSea for the best listings by collection, returning the lowest-priced active listing with details on the specific token, price, and seller. Price discovery takes one message.

Use Cases

NFT community engagement scenarios

Real ways businesses and communities use AI agents to deliver OpenSea marketplace data directly in conversations, keeping members engaged and informed.

Floor Price Alerts in Community Chat

A Discord member asks your community bot about the current floor price of your NFT project. Your AI Agent queries OpenSea collection stats, retrieves the live floor price, total volume, and number of unique owners, and shares a clean summary. The community stays informed without anyone manually checking OpenSea. Floor price questions, which make up a significant portion of community queries, resolve themselves.

Buyer Due Diligence in One Conversation

A potential buyer wants to evaluate a specific NFT before purchasing. Your AI Agent retrieves the NFT's full metadata and traits from OpenSea, checks the best current listing price, and pulls recent event history for that token showing previous sales and transfers. The buyer gets a complete picture of the asset's provenance and value without leaving the chat window.

Seller Offer Monitoring Without Constant Tab-Checking

An NFT holder wants to know if there are any good offers on their token. Your AI Agent queries OpenSea for the best offer on that specific NFT by collection slug and token ID, returns the offer amount, offerer address, and expiration time. The seller decides whether to accept, all from a quick chat interaction instead of refreshing the OpenSea offers tab repeatedly.

FAQs

Frequently Asked Questions

What marketplace data can the AI agent retrieve from OpenSea?

The agent accesses collections, individual NFT metadata and traits, active listings, offers, collection stats including floor price and volume, marketplace events like sales and transfers, smart contract details, and account profiles. All data comes from OpenSea's v2 REST API in real-time.

Can the agent create listings or make purchases on OpenSea?

The API supports creating listings and offers, but these operations require signed blockchain transactions with wallet keys. The agent can build the order parameters and provide listing data, but actual on-chain execution requires wallet interaction. The agent is best suited for read operations like price checks, collection browsing, and event tracking.

What authentication does Tars need for the OpenSea API?

Tars requires your OpenSea API key, which you can obtain from the OpenSea developer portal. The key authenticates all marketplace data requests. You also configure the base URL, which defaults to the OpenSea v2 API endpoint. Rate limits depend on your API plan.

Does Tars store NFT or collection data from OpenSea?

No. All marketplace data is fetched live from OpenSea during each conversation. Collection stats, listing prices, NFT metadata, and event histories are queried in real-time and not cached or stored by Tars. This ensures your community always sees the most current data.

Which blockchains does the OpenSea integration support?

The agent can query data across all chains supported by the OpenSea API, including Ethereum, Polygon, Arbitrum, Optimism, Base, Avalanche, Klaytn, and BNB. The chain parameter is passed with each request so the agent can filter results to the specific blockchain you need.

How is this different from users just checking OpenSea directly?

OpenSea's website requires users to navigate, search, and interpret data on their own. Your AI agent delivers the specific answer to their question instantly in conversation. Instead of browsing a marketplace UI, a community member simply asks about floor price and gets a direct answer, right where they already are chatting.

Can the agent track specific NFT sales in real-time?

The agent queries OpenSea's events endpoint with filters for event type, time range, and collection. It can retrieve recent sales, listing creations, offers, and transfers. While it polls on request rather than streaming live, it provides the most current event data available at the time of the query.

Can the agent compare prices across different NFT collections?

Yes. The agent can query stats for multiple collections in sequence and present a comparison of floor prices, total volumes, and number of owners. Community members can ask for a side-by-side breakdown, and the agent synthesizes data from each collection's OpenSea stats endpoint.
