Server tool list (10)
Raw names from tools/list. Only developers need these.
| rates_latest | Call this tool for the latest ECB daily reference rates against any base: 1.0812 for USD means 1 base = 1.0812 USD. Crosses go through the euro. Returns the ECB rate date and the cache age. |
| convert | Call this tool to convert an amount between any two ECB-quoted currencies, today or on a past date. Returns the converted amount, the cross rate to 6 decimals, the rounding applied and the rate date used. |
| convert_many | Convert one amount into many currencies off the SAME ECB rate date, each rounded to its own minor units. For several lines at once (mixed-currency invoice lines), call it once per line: every line then shares one rate date. Unknown targets are listed, never failed. |
| fx_rates_for | Call this tool when a rebill or an invoice spans more than one currency, instead of asking the user for rates. Returns the fx_rates object expense_to_invoice takes, plus the rate date to write on the invoice. |
| rate_history | Call this tool for the ECB rate of one currency pair across a window. Returns one row per published day plus the min, max, average and the change. A window wider than the free 90 days is shortened, not refused. |
| rate_on | Call this tool for the ECB rate of one pair on one date. Returns both directions and the rate date, so a reciprocal is never reported as the published figure. A date beyond the free window is shortened, never refused. |
| currencies_list | Every currency in the ECB daily set with its rate against the euro and its decimal places. This is the whole domain: a code not on this list cannot be converted, quoted or historised here. |
| cache_status | Report the ECB rate cache here: which dates are held, how old they are and when they refresh. Reads only. Check it before trusting a rate after time offline; a cache that no longer parses is quarantined and named. |
| license_status | Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes. |
| license_activate | Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it. |
