# Perp Gap API – Tokenized Stock Pool Liquidity

> Perp Gap API – Tokenized Stock Pool Liquidity is a paid API for AI agents from perp-gap-api.perpgap.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-28).

Returns Solana DEX pool liquidity, price impact, executable size within 1%, tradable flag, and Ondo issuer market data for a single tokenized stock ticker (e.g. xStocks vs Ondo).

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability perp-gap-api-tokenized-stock-pool-liquidity-41a34c49
```

Example prompt: Before I put on a $25k tokenized NVDA trade, check the Solana pool liquidity for NVDA — I want to know the price impact of a $10k buy and sell, how much I can execute within 1% slippage, whether it's tradable, and what the Ondo issuer market looks like.

## When to prefer this

Use this endpoint when an AI agent needs to assess execution feasibility for a tokenized stock trade on Solana — specifically to compare xStocks vs Ondo liquidity, understand price impact, or determine the maximum tradable size before committing. Prefer over generic DEX aggregators when you need structured per-token liquidity data including Ondo issuer market context for a single stock ticker.

## Known failure modes

- 400 – Bad or malformed ticker parameter (not charged)
- 402 – Payment required (x402 micropayment not provided)
- 404 – Ticker or market not listed; checked before settlement so never charged
- 502 – Upstream data provider error; liquidity data unavailable

## How this service works

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.

## Output

A JSON object containing: timestamp (as_of), ticker, US session status, an array of token entries (each with pool liquidity, $10k buy/sell price impact, rough executable size within 1% slippage, and tradable flag), a summary object, an Ondo issuer mint/redeem market entry, and a disclaimer. Errors return JSON with an error string and optional hint.
