# Playground

> Try every Solana AI Gateway endpoint live. Pre-filled with real on-chain examples so you can hit Send and see actual data instantly.

Every endpoint below is fully interactive. Fields are pre-loaded with real Solana mainnet examples (USDC mint, the gateway wallet, live blockhash), so you can hit **Send** with zero setup and see actual on-chain data. Change any field and rerun to test your own inputs.

<Info>
  **Paid endpoints require an API key.** Paste yours in the top-right authorization field. Don't have one yet? See [Get an API key](/guides/claim-api-key).
</Info>

<Tip>
  **How the pre-fill works.** Every field is populated from real Solana examples: the gateway wallet `Brpc8HoPo1d3Uiyo7kbERnjMqwLJJmbWxtwxHxzar6DU`, USDC mint `EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v`, and live blockhashes. Change any value and hit Send to test with your own inputs.
