Request provably fair on-chain randomness from the MagicBlock VRF oracle (Vrf1RNUjXmQGjmQrQLvJHs9SNkvDJEsRVFPkfSQUwGz). Builds an unsigned transaction that invokes request_randomness on the VRF program. Use sap_preview_transaction, sap_sign_transaction, and sap_submit_signed_transaction; do not create local signing scripts. The oracle queue defaults to the base-layer queue (Cuj97ggrhhidhbu39TijNVqE74xvKJ69gDervRUXAxGh); set ephemeral=true to use the ER queue for delegated programs. Builder fee applies. SAP MCP execution guidance: Intent: SAP MCP tool workflow. Pricing: paid builder; estimate first, then pay/build and finalize unsigned transactions locally when returned. Routing: paid hosted call; call sap_estimate_tool_cost first, then use sap_payments_call_paid_tool if the runtime cannot handle x402 natively. Signer boundary: hosted reads/builders never receive keypair bytes; value-moving results must be finalized locally when signing is required.
