Cross-chain swap (bridge aggregation)

GET 
/v1/actions/swap/x-chain

Quote a cross-chain swap across all supported bridge aggregators (Across, LI.FI, Squid, Stargate, Symbiosis, XY Finance, DZap, …) and build the winning transactions. Omit account for quote-only. Include account to build full transaction calldata. Each build quote carries approvalTarget/approvalRequired, and actions.permissions holds one ERC-20 approve per unique spender (composed routes share the 1delta composer; plain bridges use their own deposit contract) with a spender field — execute only the permission whose spender equals your chosen quote's approvalTarget. When fromChainId equals toChainId the request falls back to the spot meta-aggregator (same response shape with aggregator instead of bridge per quote, marked fallback: 'spot').
