Api Endpoint

Perp Gap API

Use before sizing a tokenized-stock trade or choosing between xStocks and Ondo for execution. For one ticker: each token's Solana pool liquidity, price impact of a $10k buy and sell, rough size executable within 1%, a tradable flag, and Ondo's issuer mint/redeem market. Bad params return 400/404 before any charge. Errors: 400, 402, 404, 502. Data, not advice.
