One-call Farcaster profile fusion. Give one of fid or username and get back the full profile (display name, bio, picture, url, location, socials), the primary Ethereum address, every verified on-chain wallet, the custody address, following and follower and cast counts, and the account age — the fused object that replaces four or five raw hub reads.

We sent a real GET request to this endpoint and it answered 402 with payment requirements we could parse.
