Which chain is the risk about?

Lido stETH exit-risk is on Ethereum. Payment for the API call is USDC on Base via x402.

Yes. Unpaid probes without amount still return 402.

Does this promise share-price growth?

No. The card reports peg, withdrawal-queue ETA, and exit liquidity for the amount you pass. Nothing is promised.
