OpenSea NFTs (Free)

NFTsFREERoutes in chatEthereumBaseArbitrum

OpenSea NFTs, free and non-gated: the NFTs a wallet owns (with images) across Ethereum, Base, and Arbitrum, NFT + collection detail, floor prices and stats, live listings and best offers — plus construction-only NFT transactions for BOTH ERC-721 and ERC-1155: transfers (ownership verified on-chain first), Seaport 1.6 sell listings the user signs gasless (payouts derived from the collection’s live fee schedule, re-validated at the relay), listing cancels, and guarded buys of live listings with locally re-encoded calldata. Never holds keys, never signs, never submits on-chain. Rate-limited. By Yeetful.

Routability

can the router discover, pick, and call it?

Not yet graded. Diagnostics check param schemas, description quality, live health, and run the actual routing planner against this service’s own tools — construction only, nothing is paid or executed.
