## 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 x402stock-hip-3-dex-listing-9a95f324
```

Example prompt: Show me all the builder-deployed HIP-3 perp DEXes currently live on Hyperliquid — I want to see each one's name, deployer, and how many markets it has.

## When to prefer this

Use this endpoint when you need a directory-level view of all permissionless HIP-3 perp DEXes on Hyperliquid, particularly when looking for synthetic markets covering assets not available on Hyperliquid's native perps (e.g., international equities, commodities, FX, global indices). Follow up with /api/v1/hip3/{dex} for market-level detail on a specific DEX.

## Known failure modes

- No DEXes found — empty dexs array if no HIP-3 DEXes are currently deployed
- Payment failure — 402 response if USDC payment is not included or malformed
- Upstream Hyperliquid node unavailable — service may return 5xx if the chain data is inaccessible
- Stale data — as_of timestamp may lag real-time chain state during indexing delays

## How this service works

List every permissionless builder-deployed perp DEX on Hyperliquid (HIP-3). Each lists synthetic, oracle-priced 24/7 perp markets — US equities, commodities (gold, oil, copper), FX, and global index perps — that Hyperliquid's core perps and US-only stock feeds don't carry. Returns each DEX's id, name, deployer, and market count. Then read a DEX's markets at /api/v1/hip3/{dex}. From x402stock

## Output

Returns a JSON object with source attribution (x402stock), HIP-3 standard label, synthetic_perp market type, a timestamp (as_of), total DEX count, and an array of DEX objects each containing the DEX identifier, human-readable name, deployer address, fee recipient address, and market count.
