check_referral_link
Checks whether a URL carries CoinRebate's own current referral code (allowlisted exchange hosts only). This is a self-check for CoinRebate links: a link carrying someone else's code is reported as stale_code even though it may be perfectly valid. For a neutral inspection of any exchange link, use inspect_exchange_link.

inspect_exchange_link
Inspects an exchange sign-up or referral link and reports evidence on five separate points: whether the domain is a verified official domain of a listed exchange, whether it is reachable, whose referral code it carries, how CoinRebate's records list the exchange for a given country, and what rebate (if any) is configured. Unknown items are reported as unknown. It never says a link is safe, never probes unrecognized domains, and never suggests a replacement link. Read-only.

recommend_fee_option
Decide which covered exchange has the lowest effective trading fee for a specific user, instead of returning a table. Requires the user country. Returns one verdict plus its net fee, the quantified annual cost, the assumptions and what is NOT modelled, and a commercial disclosure. Abstains (neutral fee table only) when the country is missing or unsupported, the upstream data is unreliable, or the top venues are genuinely tied. In high-regulation jurisdictions it returns an objective fee table with no signup link.
