}Execute a conversion
Consume a quote. Your from_asset balance is checked now, not at quote time. The call normally returns a terminal completed or failed; a rare processing means the outcome is not yet known — poll GET /v2/conversions/{id} or wait for conversion.completed / conversion.failed. Requires an Idempotency-Key.

}Authorizations
Your Jenzy API key: Authorization: Bearer jz_live_…
Headers
Required. A key you mint per conversion attempt (a UUID works). A retry with the same key and body returns the same conversion — including finishing one whose outcome was still processing. The same key with a different body is a 409.
Body
A quote_id from POST /v2/conversions/quotes.
Response
The conversion, usually already terminal.
An asset code as GET /v2/assets lists it — uppercase, never compound (KES, USDT; never USDT-TRON). Network and rail live on the payment object.
1"KES"
An asset code as GET /v2/assets lists it — uppercase, never compound (KES, USDT; never USDT-TRON). Network and rail live on the payment object.
1"USDT"
What you paid, in from_asset.
"1000.00"
What you received (or will, on completed), in to_asset.
"7.68075"
The quote’s rate, for display.
"130.19561892"
completed — your balances moved. failed — nothing moved; see failure. processing — accepted, outcome not yet known; rare and short-lived, poll GET /v2/conversions/{id} or wait for the webhook.
processing, completed, failed Set only on failed.
