Use/Do Not Use

Use when:

• Migrating code that calls api.jup.ag/swap/v1/quote, api.jup.ag/swap/v1/swap-instructions, or ultra-api.jup.ag.
• Updating Jupiter swap endpoints to v2.
• Switching from Metis two-step flow to the unified /build or /order endpoint.

Do not use when:

• Building a new Jupiter integration from scratch (use integrating-jupiter skill instead).
• Working with non-swap Jupiter APIs (Lend, Trigger, Recurring, etc.).
