jup-ag

Comprehensive guidance for integrating Jupiter APIs (Swap, Lend, Perps, Trigger, Recurring, Tokens, Price, Portfolio, Prediction Markets, Send, Studio, Lock, Routing). Use for endpoint selection, integration flows, error handling, and production hardening.

Interact with Jupiter Lend Protocol. Read-only SDK (@jup-ag/lend-read) for querying liquidity pools, lending markets (jlTokens), and vaults. Write SDK (@jup-ag/lend) for lending (deposit/withdraw) and vault operations (deposit collateral, borrow, repay, manage positions).

Migration guide from Jupiter Metis (v1) or Ultra to Swap API v2. Use when migrating existing Jupiter swap integrations, updating base URLs, or transitioning from quote+swap-instructions to the unified build endpoint.

Use when a user mentions Jupiter token verification, VRFD eligibility, paying 1000 JUP to verify a token, submitting a verification request, or updating metadata via the Jupiter express verification flow.

Draft a new release by bumping the version and updating the changelog. Use when changes are committed and ready to ship.

Document a Jupiter API/feature from verifiable evidence instead of assumptions. Probes the live API, optionally runs the real transaction lifecycle on mainnet from the operator's workbench, cross-references the SDK and first-party FE source, then writes docs, product-learning entries, a DX findings file, and a changelog entry. Use when documenting a new or changed endpoint/feature where behaviour must be verified, not guessed.
