Fund

Transfer funds to a UID

Transfers funds from the authenticated organization to an Infini UID. Requires fund.withdraw permission.

V1 supports same-currency transfers in USDT, USDC, or USD only. source_currency is optional and defaults to token_type; when supplied, it must equal token_type. The transfer has no fee, so the amount deducted from the sender equals the amount received by the recipient.

request_id is optional. When supplied, it must be a UUID and acts as the idempotency key. A retry by the same organization with an already completed request_id returns status=completed and is_duplicate=true.
