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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# OpenSea Tool SDK Build, register, and gate AI-callable tool endpoints using the OpenSea Tool Registry (ERC-8257) on Base. ## When to use this skill (`scope_in`) Use `opensea-tool-sdk` when you need to: - Scaffold an AI-callable tool endpoint (HTTPS, JSON Schema, `.well-known` manifest) for Vercel, Cloudflare, or Express - Register a tool onchain on the Base ToolRegistry so other agents can discover it - Gate access via x402 pay-per-call (USDC) or predicates (ERC-721/ERC-1155 ownership, subscriptions, composites) - Call a gated tool: SIWE auth (`authenticatedFetch`), 402 payments (`paidFetch`), or both (`paidAuthenticatedFetch`) ## When NOT to use this skill (`scope_out`, handoff) | Need | Use instead | |---|---| | Query NFT/token data, search, collection stats | `opensea-api` | | Buy/sell NFTs | `opensea-marketplace` | | Swap ERC20 tokens | `opensea-swaps` | | Set up wallet signing providers | `opensea-wallet` | This SDK is for tool *providers and consumers*. To query OpenSea marketplace data (floor prices, listings, trades), use the [`opensea-api`](../opensea-api/SKILL.md) skill instead. ## Concepts | Term | Meaning | |------|---------| …

How to install
mdr add bankrbot/skills/opensea-tool-sdk@sha256:70bb8d7a782733b1The line at the top of this page pins the label git:20260508.bcea4b2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
