}🟢get_invoice(asset, chain, currency, endpoint_id)
Request a payment invoice for any SqueezeOS endpoint. Returns destination address, amount, and payment_options for XRPL (RLUSD or USDC), Xahau (native XAH), Base (USDC), or Solana (USDC-SPL). Pass currency='USDC' and chain='solana' for Solana; pass asset='XAH' (or chain='xahau') for the Xahau rail. Xahau invoices for third-party endpoints also return fee_required/fee_amount/fee_pay_to/fee_memo_hex: a flat 0.01 XAH facilitator fee paid as a second Xahau Payment (SML endpoints are fee-exempt; the XRPL rail has no facilitator fee). Free.
