Resolve a Farcaster cast — identified by username/fid + short hash, or by its full 40-hex hash — and return the URL that opens it in a target Farcaster client app (or all supported apps). Also returns the author's signed-contract status; URLs are returned regardless of signed state.
Target Farcaster client app, or "all" to return every supported client's URL.
Author's Farcaster fid (numeric account id).
Full cast hash — 40 hex characters, with or without the 0x prefix. Identifies the cast on its own; the most reliable form for fresh casts.
Author's Farcaster username, without the @.
Abbreviated cast hash as it appears in share URLs — 4-39 hex characters, 0x prefix optional. Requires username or fid alongside it.
