Questions about das_getAssetsByOwner
Get all NFTs/assets owned by a wallet via DAS (supports pagination). SAP MCP context: Protocol das; operation class read. Use for read-only DAS NFT and asset discovery by owner, creator, collection, or search query. Prefer DAS reads before Metaplex writes when validating existing assets for an agent profile, collection, or metadata update. SAP MCP execution guidance: Intent: read/discovery workflow. Pricing: paid read-premium; estimate first, then use sap_payments_call_paid_tool when the runtime cannot replay x402 natively. Routing: paid hosted call; call sap_estimate_tool_cost first, then use sap_payments_call_paid_tool if the runtime cannot handle x402 natively. Signer boundary: hosted reads/builders never receive keypair bytes; value-moving results must be finalized locally when signing is required.
