Alchemy NFT Discovery and Contract Read Workflow

Overview

Build an NFT discovery workflow with Alchemy NFT API v3 and isolate typed on-chain reads through viem. This workflow produces a reviewable artifact and negative-path evidence before any live side effect.

Prerequisites

• Current first-party Alchemy documentation for the selected product, chain, feature, client, authentication method, limit, and lifecycle.
• Named product, application, security, data/privacy, budget, release, and operations owners appropriate to the requested scope.
• Synthetic or approved non-production fixtures, a credential canary, explicit success criteria, and a tested rollback boundary.

Current Contract

NFT API responses, metadata availability, spam classification, pagination, and supported networks are endpoint-specific. NFT indexing is not chain finality, and cached media is not proof of ownership. Contract state reads use the declared viem chain and ABI; ownership-sensitive decisions require an explicit block/finality policy.

Authentication

Use a scoped application API key in the server boundary. Validate owner and contract addresses before lookup. Treat queried owner addresses, collections, and behavioral analytics under the product's privacy and retention policy.
