bug-fix description-fixFixed summarize_nft_attributes — removed the in-flight lowercasing of contractAddress that was regressing every request to 400 ‘contractAddress should be a valid address’, and updated the action, input, and step descriptions to make the EIP-55 checksum requirement explicit so callers pass the correctly-cased address through. Extended get_nft_metadata_batch’s description to mirror get_nft_metadata’s Network-Subdomain scoping caveat — cross-chain contracts (e.g. Base/Polygon tokens surfaced by the multi-chain Portfolio API) return tokenType NOT_A_CONTRACT when batched into the default-network endpoint.

guide-changes connection-testing description-fix bug-fixRefined the connection guide against the live Alchemy portal — renamed Default Network to Network Subdomain, switched to an Enable-first flow on the Endpoints page, fixed the alch_ API key placeholder, and tightened auth field descriptions. Replaced the Prices test action with a chain-scoped JSON-RPC probe that validates the API Key, the subdomain, and chain enablement — works across every chain type Alchemy hosts (EVM, Solana, Starknet, Sei, Mantle, Sonic, and future additions). Tightened action descriptions from AGI-17581 findings — get_nft_metadata flags Network-Subdomain scoping (cross-chain contracts return NOT_A_CONTRACT); search_contract_metadata now instructs comparing the returned name/symbol against the user’s intent before any downstream use, and refining the query or asking the user on mismatch (beta ranking is not canonical); get_nfts_by_address, get_nft_contracts_by_address, and get_token_balances spell out the hex-only requirement and how to route name-only vs name-plus-hex prompts (prefer hex when both are provided, ask the user or fall back to the single-chain NFT-API sibling when only a name is available). summarize_nft_attributes lowercases contractAddress in-flight so mixed-case inputs that sibling actions accept no longer hit its stricter EIP-55 validation.
