  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

Capabilities

Tools 12

calculate_trading_cost

Do not call this tool for investment advice (what or how much to buy), placing orders, signing in to exchange accounts or moving funds; CoinRebate cannot do those, so answer such requests without calling it. Estimate the taker-fee cost of a trading volume on one exchange, with and without the CoinRebate referral discount, using the benchmark taker fee from CoinRebate's published fee table. Returns the fee on that volume, the difference, a yearly figure that assumes the volume is monthly, and the date of the fee-table entry used. Use it only for questions about exchange trading fees and fee discounts.

Discovered
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.

Discovered
compare_fees

Do not call this tool for investment advice (what or how much to buy), placing orders, signing in to exchange accounts or moving funds; CoinRebate cannot do those, so answer such requests without calling it. Compare the benchmark trading fees from CoinRebate's published fee table across the covered exchanges for one purpose (spot or futures). Returns the exchanges ranked by lowest taker fee after the CoinRebate referral discount. Pass a country code for compliance-filtered results. Use it only for questions about exchange trading fees and fee discounts.

Discovered
get_compliant_exchanges

Do not call this tool for investment advice (what or how much to buy), placing orders, signing in to exchange accounts or moving funds; CoinRebate cannot do those, so answer such requests without calling it. Get exchanges available in a specific country, filtered by the CoinRebate compliance matrix. Essential for regulatory compliance. Use it only for questions about which exchanges are available in a country.

Discovered
get_exchange_fees

Do not call this tool for investment advice (what or how much to buy), placing orders, signing in to exchange accounts or moving funds; CoinRebate cannot do those, so answer such requests without calling it. Get the benchmark trading fees from CoinRebate's published fee table for every covered exchange: spot and futures maker/taker fees (VIP 0 base tier) and the same fees after the CoinRebate referral discount. These are published rates, not live order-book data: fees.fee_table_updated is the date an exchange's entry in the table was last updated, while data_source and fetched_at only describe CoinRebate's automated refresh check. Use it only for questions about exchange trading fees and fee discounts.

Discovered
get_exchange_referral

Do not call this tool for investment advice (what or how much to buy), placing orders, signing in to exchange accounts or moving funds; CoinRebate cannot do those, so answer such requests without calling it. Look up the referral code, fee discount and signup link that CoinRebate lists for one exchange, together with the published maker and taker fees of that exchange before and after the discount. Pass a country to apply the availability records CoinRebate keeps for that country. Use it only for questions about an exchange referral code, signup link or fee discount.

Discovered
get_latest_news

Do not call this tool for investment advice (what or how much to buy), placing orders, signing in to exchange accounts or moving funds; CoinRebate cannot do those, so answer such requests without calling it. Get CoinRebate's most recently published English-language articles (market analysis, guides and news), newest first: up to five by default, at most 20. Returns each article's title, publication date and link, and says so when the newest English-language article is more than three days old. Use it only when the user asks what CoinRebate has published.

Discovered
get_perp_stats

Gets daily, weekly, 30-day, and historical weekly-rank statistics for a Binance TradFi perpetual from official Binance klines.

Discovered
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.

Discovered
list_tradfi_perps

Lists Binance USDⓈ-M perpetuals on US, HK, KR, and CN stocks plus commodities from the official exchangeInfo endpoint.

Discovered
recommend_fee_option

Do not call this tool for investment advice (what or how much to buy), placing orders, signing in to exchange accounts or moving funds; CoinRebate cannot do those, so answer such requests without calling it. 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. Use it only for questions about exchange trading fees and fee discounts.

Discovered
search_guides

Searches CoinRebate's published guides by keyword (any language) and returns matching articles with title, one-line description and URL. Read-only; results are informational articles, not referral links.
