Tools (6)

benefits_api_docsread-onlyUse when you need field definitions, ordering guarantees or the error format before calling another tool.
benefits_examplesread-onlyUse to copy a working example call instead of guessing tool arguments.
compare_bonusesread-onlyUse 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.
expiring_soonread-onlyUse 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.
get_bonusread-onlyUse 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.
search_bonusesread-onlyUse 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.
