Solana API Reference

L1 - Summary

The exact request shapes, response fields, and unit traps for every Solana surface the desk touches. Read this before writing any new call; never guess an endpoint.

L2 - Method

1. Jupiter: quote-only GET https://api.jup.ag/swap/v2/order with inputMint, outputMint, amount, slippageBps and x-api-key from JUPITER_API_KEY. Never send taker. Never call /execute, /build, or /submit. Unit trap: v2 priceImpact is percentage points; divide by 100 for a ratio. The quote is informational, never the fill.
2. Solana RPC (common): getBalance, getTokenAccountsByOwner, getAccountInfo (mint / freeze authority), getRecentPrioritizationFees, getTokenLargestAccounts, getTransaction / getSignaturesForAddress.
3. Usage rule: when in doubt about an endpoint, re-read this skill or the live documentation rather than guessing.

Failure modes

• Deprecated v1 swap endpoints: do not use them; v2 order is the only Jupiter path.
• Guessed parameters: rejected. Every field above is exact.
• Quote treated as fill: the fill comes only from exec.place.
