Use cases

Focused recipes for common Vector integration patterns. Every request requires an api-key header — see Get API access.

Use case	Covers
Same-chain token swap	Quote, rank, and build in a single call with GET /build-best-path.
Gasless swaps with Permit2	Swapping without holding native gas: sign a typed payload and let Vector handle submission.
Cross-chain swap	Where cross-chain routing stands today and how to structure requests for it.
HyperCore spot swap	Quote against Hyperliquid's Core order book and execute it as a gasless order.

For the full flow with every endpoint spelled out step by step, start with End-to-end swap. Per-endpoint schemas live in the API reference.
