estimate_quantity_or_probabilityEstimates an uncertain number, or the probability that an event happens by a date, from a question in plain language, and returns a calibrated range and probability distribution. Use this when the user asks how much, how many, how big or how long something is or will be (market…
get_estimate_resultReads one estimate you already requested, by its estimate_id. Use this when a tier-3 (deep research) estimate came back with status "pending" and you want to know whether it is finished, or to show an earlier estimate again. Tier-3 results are only delivered this way (or to a ca…
list_my_estimatesLists the past estimates on your account, newest first. Use this when the user wants to find an earlier estimate ("what did I estimate last week?") or has lost an estimate_id. Returns estimates, each with estimate_id, created_at, question, unit, target_horizon, point_estimate, e…
send_feedbackSends a short report about Fermi to the team that builds it. They read every report and use it to fix problems and decide what to build, so honest feedback, good or bad, is useful. Use this when: - a Fermi tool returned an error (send it right away), behaved unexpectedly or gave…
buy_creditsBuys Fermi credits by charging the card saved on your account, and returns the new balance. Use this when the user explicitly asks to buy or top up Fermi credits. Returns credits_purchased, new_balance and payment_status. If no card is saved yet, nothing is charged: it returns a…
check_account_and_creditsReports who you are to Fermi and what you can spend: whether you are using Fermi without an account or with one, your credit balance or free estimates left today, and what each tier costs. Use this before a paid estimate to check the price or balance, after one to see what is le…
