The published rate converting currency into the organization's home currency on date

GET /fx/reference-rate

The published rate converting currency into the organization's home currency on date (YYYY-MM-DD): rate units of the home currency per one unit of currency, the central bank's figure for the last day it published on or before date, at most a fortnight back.

The bank local to the home currency is asked first (the RBA for AUD, the RBNZ for NZD, the ECB for EUR, the Bank of England for GBP, the Fed for USD, the Bank of Canada for CAD, Norges Bank for NOK, Danmarks Nationalbank for DKK); then the ECB, the Fed, the Bank of England, the Bank of Canada, Norges Bank, Danmarks Nationalbank, the RBA and the RBNZ in turn, each directly when the currency is its own or as a cross through it (via). source and rateDate say whose figure and which day; the home currency itself answers rate 1 with no source. The rates are the banks' own figures, kept from 1999-12 and refreshed every few hours from Frankfurter's relay of each bank's series; the RBNZ's end 2026-10-15 (its terms forbid automated access), after which NZD converts through the ECB's cross. 409 ReferenceRateUnavailable when no bank publishes the currency (unquoted) or none did in the fortnight before date (no-rate). Read-only.

Errors

Every refusal is a status and a JSON body whose _tag names it. A refused call changes nothing.

`401`

Refusal	What it means	What to do
`Unauthorized` reason	The token is missing, expired or not one Manifold issued.	Get a fresh token and send the call again.
`TokenAlreadyUsed` tokenId	A single-use app token was already spent.	Mint a new token for this call.

`402`

Refusal	What it means	What to do
`SubscriptionRequired` status	The organization's subscription has lapsed, so writes are refused.	An owner settles billing. Reads still work meanwhile.

`403`

Refusal	What it means	What to do
`TenantRequired` userId	The token names no organization.	Choose the organization, then get a new token.
`ScopeRequired` required	The token's roles do not grant the scope this call needs.	Ask an owner or admin for a role that grants it.

`409`

Refusal	What it means	What to do
`ReferenceRateUnavailable` currency, homeCurrency, date, reason	No exchange rate was published for the currency near that date.	Send the rate yourself, or pick another date.
`MirroredFromSource` source	This area is fed by your source system until the organization goes live.	Make the change in the source system, or go live first.

`503`

Refusal	What it means	What to do
`RequestLogUnavailable` tokenId, reason	The service could not record the request, so it did nothing.	Try again shortly.
