    Why it is in this group

    • The description's first verb is "call": a word for a change.
    Description, as the server wrote it
    Call this right after you send a stablecoin deposit to have it picked up sooner: it tells the system to check your deposit addresses now. It moves no money and is free. If it comes back with nothing, you don't have a deposit address yet, so add one from the web dashboard.

      What this check looks for
    Description, as the server wrote it
    The tool to call first, and it's free with no account. Lists the phases the model can report, the timeframes and currencies covered, and a short card for each phase explaining what it means and what tends to come next. Also returns the current pricing, so you can work out what a paid call costs before you make one.

  • trendvane_phase_resolution_statsFree, and how you read meaning into a phase.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Free, and how you read meaning into a phase. For each one it shows what usually happens next, how often a trend keeps running, and how the typical move rewarded you against how far it drew down first. Every figure comes with the number of past cases behind it. It's a behavior model built from years of Bitcoin history, not live per-coin data, so pair it with trendvane_get_phase.

  • bfxpremium_get_premiumGet the Bitfinex cross-exchange premium for BTC: the latest CLOSED daily residual (in basis points) and its regime state (calm, building, or stress).No findings

    Why it is in this group

    • The name "bfxpremium_get_premium" says "get": a word for reading.
    Description, as the server wrote it
    Get the Bitfinex cross-exchange premium for BTC: the latest CLOSED daily residual (in basis points) and its regime state (calm, building, or stress). This is a paid call at a flat per-call price. Set `updates` to true to also append the rolling intra-day reading from the last closed sub-daily bucket; the price is the same either way. If a required exchange is unavailable the call returns an error and is not charged.

  • system_get_balanceCheck your prepaid balance before a paid call.No findings

    Why it is in this group

    • The name "system_get_balance" says "get": a word for reading.
    Description, as the server wrote it
    Check your prepaid balance before a paid call. Shows the credit you have left to spend, anything on hold, any bonus credit and when it expires, whether the account is paused, the current pricing, and the deposit addresses on your account. It's free. If you run out, paid calls are turned away until you top up. To add a deposit address, sign in to the web dashboard.

    Why it is in this group

    • The name "system_get_notifications" says "get": a word for reading.
    Description, as the server wrote it
    Read your account messages: support, billing, and account notices. With no arguments you get the ten most recent in each group, each with a cursor; pass a category and cursor to page further back. It's read-only and free, and it never marks anything as read. Security alerts aren't available here, and any group you've switched off for API access won't show up.

    Why it is in this group

    • The name "system_get_usage" says "get": a word for reading.
    Description, as the server wrote it
    Your history of paid calls, newest first. For each one it shows which tool you used, the coins and timeframes, how much data came back, and what it cost. Free. Page back through older calls with `before`, using the cursor the previous page returned.

    Why it is in this group

    • The description's first verb is "get": a word for reading.
    Description, as the server wrote it
    Get phases for several coins and timeframes in one paid call. Set `kind` to 'boundary' for the settled last-closed-bar reading or 'updates' for the still-forming one. The cost scales with how many readings come back, which is your coins times your timeframes.

  • trendvane_get_phaseGet the current market phase for one coin, across a timeframe.No findings

    Why it is in this group

    • The name "trendvane_get_phase" says "get": a word for reading.
    Description, as the server wrote it
    Get the current market phase for one coin, across a timeframe. This is a paid call. Set `kind` to 'boundary' for the reading from the last closed bar, which is settled and won't change, or 'updates' for the live reading still forming inside the current bar. Leave `tf` off, or set it to 'all', for every timeframe.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
