Tools: search_bonuses get_bonus expiring_soon compare_bonuses benefits_api_docs benefits_examples
search_bonuses | Use when a user wants to find a US bank account, savings, credit card or brokerage signup bonus, or asks which offers are worth opening. Returns matching offers sorted by bonus value, highest first — except when balance_transfer is true, which sorts by intro window instead. params: bonus_type, state, min_bonus_amount_usd, direct_deposit_required, query, balance_transfer, limit |
get_bonus | Use before recommending an offer, to read its exact requirements, minimum deposit, direct-deposit rules, expiry date, state availability and the date its terms were last verified. Quote the requirements rather than paraphrasing money amounts. params: id* |
expiring_soon | Use when timing matters — a user asking what is about to end, or whether to act now. Offers with no stated end date are never included here. params: days |
compare_bonuses | Use when a user is choosing between specific offers. Returns each offer's key fields plus a summary naming the highest bonus and the earliest expiry. params: ids* |
benefits_api_docs | Use when you need field definitions, ordering guarantees or the error format before calling another tool. params: none |
benefits_examples | Use to copy a working example call instead of guessing tool arguments. params: none |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
