Before creating an LSPS2 invoice that requires JIT channel negotiation, check if the node already has sufficient incoming capacity to receive the payment directly. When the receivable capacity (with a 5% buffer for fees) exceeds the invoice amount, create a regular invoice instead of negotiating with the LSP. This avoids unnecessary LSP fees and channel opening costs when the node can already receive the payment. The capacity check: - Sums receivable_msat across all CHANNELD_NORMAL channels with connected peers - Applies a 5% buffer to account for routing fees - Falls back to JIT negotiation if capacity is insufficient or for 'any amount' invoices
Replace call_raw with call_typed when creating a regular invoice in the LSP invoice handler. This provides better type safety by using the generated cln_rpc::model::requests::InvoiceRequest and cln_rpc::model::responses::InvoiceResponse types. Benefits: - Compile-time type checking for request/response fields - No manual hex decoding needed for payment_hash/payment_secret - Access to created_index field from the response - Cleaner code without custom request/response structs
