What OpenSea (BYOK) is for

OpenSea (BYOK) lets an AI assistant read your own OpenSea data through the OpenSea API with a key you supply (OpenSea API key). Read-only: 12 tools (get_collection, get_collection_stats, list_trending_collections, list_top_collections, list_nfts_by_account, list_nfts_by_collection, get_nft, list_nft_owners, list_collection_holders, list_token_balances_by_account, list_trending_tokens, search). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.opensea.io. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by OpenSea. OpenSea and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "What is the doodles-official collection on OpenSea?"
• "What is the floor price and total volume of doodles-official?"
• "Which NFT collections are trending on OpenSea in the last day?"
• "What are the top NFT collections by 7 day volume?"
• "Which NFTs does 0xabc... hold on Ethereum?"
• "Show some NFTs in the doodles-official collection"

What it does

• get_collection: Get one NFT collection's details: name, description, category, links, total supply, fees, contracts and pricing currencies.
• get_collection_stats: Get a collection's floor price, owner count, total sales and volume, plus sales and volume per time interval.
• list_trending_collections: List NFT collections trending by sales activity over a timeframe, optionally filtered by chain or category.
• list_top_collections: List top NFT collections ranked (descending) by volume or another stat, optionally filtered by chain or category.
• list_nfts_by_account: List the NFTs a wallet owns on one chain, optionally for one collection, with name, collection, token ID and estimated value.
• list_nfts_by_collection: List the NFTs in a collection with name, token ID, image and metadata link; page with the next cursor.
• get_nft: Get one NFT's name, description, image, traits, rarity rank, owners and collection.
• list_nft_owners: List the wallets that own a specific NFT with quantities (useful for ERC-1155 tokens that have many owners).
• list_collection_holders: List the top holders of a collection with the number of items and percentage of supply each holds.
• list_token_balances_by_account: List the fungible token balances of a wallet across chains with price, USD value and spam status, sorted by value by default.
• list_trending_tokens: List trending fungible tokens across chains with price, 24 hour change, volume, market cap and holder count.
• search: Search collections, tokens, NFTs and accounts on OpenSea by text; results are ranked by relevance.

BYOK key

You bring your own OpenSea OpenSea API key (https://opensea.io/settings/developer). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.opensea.io over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

What it is not

Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by OpenSea. OpenSea and its logos are trademarks of their owners and are used only to say which service the connector works with. It is read-only: it never creates, changes, sends or deletes anything in your OpenSea account.

OpenSea (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What OpenSea (BYOK) is. OpenSea (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own OpenSea data: Read NFT collections, stats, NFTs held by a wallet, owners, trending tokens and search results from OpenSea with your own API key. You bring your own OpenSea OpenSea API key; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one OpenSea call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to api.opensea.io, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If OpenSea rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What OpenSea receives. The request we make on your behalf, including the key and the arguments, under OpenSea's own terms and privacy policy. OpenSea acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer OpenSea gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your OpenSea data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. OpenSea (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at OpenSea at any time to end all access.

Children. OpenSea (BYOK) is a general-audience service operated by the adult using the assistant, under OpenSea's own age rules.

Changes. We will post changes here with a new effective date.
