Check whether a wallet holds a valid (non-expired) key for a specific Unlock Protocol lock, read-only. Returns status (valid, expired, no_key, not_a_contract, or not_a_lock), lock name, tokenId, and expiration. Use this when you already know the lock address to check; use unlock_list_keys instead when you need every lock a wallet holds and don't know the addresses up front. The verdict normally comes from the lock's own getHasValidKey; on locks that predate it, the call falls back to comparing the read expiration to the local clock and reports verdictSource: "local_clock" (absent when the contract answered). Set requireContractVerdict to fail instead of accepting that fallback.

Read an Unlock Protocol lock's public shape from the chain, read-only: name, symbol, key price/currency, expiration duration, max keys, and total keys sold.

List every Unlock Protocol key a wallet holds across locks on a network, via the Unlock subgraph, read-only. Returns each key's lock address and name, tokenId, expiration, and validity, sorted by expiration descending and capped at 100 results with a truncation flag. Use this when you need every membership a wallet holds and don't know the lock addresses up front; use unlock_check_membership instead when you already know which lock to check.
