  Back to the connector overview, authentication methods, and actions.

<Update label="v1.0.0" description="7 Sept 2026">
  `release`

  Promoted to GA. Version normalized to 1.0.0 in line with the GA versioning policy (GA connectors are versioned 1.0.0 or higher); no functional changes in this version.
</Update>

<Update label="v0.1.3" description="2 Sept 2026">
  `bug-fix`

  Standardized action category capitalization for more consistent portal filters.
</Update>

<Update label="v0.1.2" description="25 Aug 2026">
  `bug-fix` `description-fix`

  Fixed 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.

<Update label="v0.1.1" description="19 Aug 2026">
  `guide-changes` `connection-testing` `description-fix` `bug-fix`

  Refined 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.
