Claim this listing →Overview
The OpenSea Agent Skill is an official ProjectOpenSea tool for AI coding assistants that lets agents interact with the OpenSea API to query NFT and token data, list NFTs, fetch listings/offers, and swap ERC-20 tokens via CLI, scripts, or the OpenSea MCP server (mcp.opensea.io). It works with MCP-compatible apps (Claude, Cursor, VS Code, etc.) and supports managed signers including Privy, Turnkey, Fireblocks, and Bankr. Listed here as the agent skill/MCP, not the marketplace itself.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

A remote server: your client connects to the project's endpoint. Installing runs third-party software under your own credentials. Sato Hub publishes the documented invocation and, where the harness reproduced it, the date it did — neither is a safety review.

State changed on 2026-09-13 (responding → failing), 2026-09-14 (failing → responding).
This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 37 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Every one of them passed, so the rate covers them too.
Last 30 days — to 2026-10-24, one point per UTC day
A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
