# Agent402: Perpetual DEX Listings via Hyperliquid

> Agent402: Perpetual DEX Listings via Hyperliquid is a paid API for AI agents from agent402.tools, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-30).

Returns a list of perpetual decentralized exchanges (perp DEXs) including market counts, deployers, fee recipients, OI caps, and deploy auction status from Hyperliquid.

## 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 agent402-perpetual-dex-listings-via-hyperliquid-75948bce -d '<json body>'
```

Example prompt: Can you pull the full list of perpetual DEXs on Hyperliquid, including their market counts, deployer addresses, OI caps, and whether a deploy auction is currently active?

## When to prefer this

Choose this endpoint when you need structured, on-demand data about perpetual DEXs on Hyperliquid including market statistics, deployer metadata, and deploy auction state — especially in agentic workflows where no API key or signup is feasible and pay-per-call via x402/USDC is acceptable. Prefer this over manual on-chain queries or scraping when you need a clean, normalized JSON response with OI caps and auction data in a single call.

## Known failure modes

- Upstream Hyperliquid data unavailable — may return stale or empty data
- Payment not fulfilled — x402 or MPP payment required before response is returned
- Malformed POST body — though body fields are not required, incorrect content-type may cause rejection
- Network timeout if Hyperliquid source is slow to respond

## How this service works

Every builder-deployed perpetuals dex on Hyperliquid (HIP-3): dex name, full name, deployer, oracle updater and fee recipient, how many markets it lists (active vs delisted, so a wound-down dex reads as one), how many assets carry a streaming open-interest cap and the cap total, plus the current perp-deploy auction (start, end, start/current/end gas). The native dex is not a row; use perp-markets for it. Keyless public data.

## Output

A JSON object containing an array of perp DEX entries (each with DEX ticker, full name, deployer address, fee recipient, market counts, oracle updater, OI cap in USD, and funding multipliers), a total count, the data source (e.g. 'hyperliquid'), a fetchedAt ISO timestamp, and a deployAuction object indicating whether an auction is active along with its start/end times, gas parameters, and duration in seconds.
