Swap

Spot swap and cross-chain swap

Spot swap (meta-aggregator)

Execute a spot swap via the meta-aggregator. Omit `account` for quote-only. Include `account` to build full transaction calldata.

Cross-chain swap (bridge aggregation)

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'`).
