Get channel rate

GET
/channels/{id}/rate

Get the current indicative rate for the channel's conversion. It is an estimate for showing at payment initiation, not a locked quote: the live rate at the moment a deposit confirms on-chain is applied.

The pair is fixed by the channel: from is always the channel's currency (what the end user sends) and to is always the currency of the channel's crediting wallet (identified by the channel's walletId).

from*string

The channel's pay currency, always equal to the channel's currency. This is what the end user sends to the channel's addresses.

to*string

The currency of the channel's crediting wallet (identified by the channel's walletId). This is what deposits convert to before they are credited.

rate*string

Indicative rate as an exact decimal string: 1 unit of from equals rate units of to.

Get channel payment details GET

Fetch particular channel payment details, including its on-chain evidence and conversion outcome.

Get channel checkout URL GET

Get a link to the hosted Volt Checkout page for the channel. The page shows the payer the channel's deposit addresses, one per network, and the current indicative rate of the channel's `currency` to EUR. Both links are valid for one hour. Once they expire, call this endpoint again to get fresh ones. Do not cache or store the links, and do not log them: anyone holding a link can open the channel's checkout page. The response is sent with `Cache-Control: no-store`.
