# VWAP breadth: the canary in the coal mine
Hyperliquid market breadth as an API: the share of perps above session VWAP, every minute since August 24 2026. New 0xArchive endpoint, first-week data inside.
*0xArchive Product · new endpoint launch*

![Two-pane chart, August 24 to 31 2026. Top: BTC price as a pale line. Below: a minute-by-minute tape where green height is the share of Hyperliquid perps above session VWAP and red the share below, flipping inside every UTC session.](https://api.0xarchive.io/cms-assets/2026/09/0a9381a0-b6d5-44fd-9845-52b326c344db.webp)

Top pane: BTC price, 15-minute closes. Bottom: every 1-minute snapshot as a green/red split; green height is the share of coins above the day's average price. Bitcoin's line barely moved all week while the tape under it flipped from 176 of 178 coins under water to 174 of 178 winning. That gap is the information the index chart cannot show.

Hyperliquid lists hundreds of perps and you watch three of them. [0xArchive](https://0xarchive.io/) 's new breadth endpoint answers one question, every minute: how much of the market is actually winning right now. 100 means every coin is above the day's average price. 0 means the whole board is under water. Here is what it measures, its first week, and three things to know before you trade on it.

![Four cards on the breadth endpoint: one number from 0 to 100 every minute; breadth's century of track record on equities desks; 176 of 178 coins under water on August 28 while Bitcoin barely moved; three things to know before trading it.](https://api.0xarchive.io/cms-assets/2026/09/b19e97cd-8893-4ce9-83bf-b5589016d645.webp)

The endpoint in four cards. The green and red tapes are the real first week, every one-minute reading from Aug 24 to 31.

## Watching one price when Hyperliquid trades hundreds of perps

BTC is up half a percent, so the market is fine. On Hyperliquid that read fails daily. The tape is hundreds of coins, and the majors can hold steady while everything else bleeds.

Checking used to mean flipping through hundreds of charts. Now it is one request. Every minute, 0xArchive counts every coin on the venue and writes down how many are winning. The full history is saved.

> On August 28 at 02:32 UTC, Bitcoin had barely moved. 176 of 178 coins on Hyperliquid were under water.

## What VWAP breadth measures

Every reading carries four numbers. One real minute of data, Aug 28 at 12:00 UTC, explains all of them.

![Four definition cards from the real August 28 12:00 UTC reading: the day's average price as BTC against its running average; breadth 28.57%, 50 above and 125 below; eligible 175 of 253 as a dot grid; coverage 0.69 as a filled bar.](https://api.0xarchive.io/cms-assets/2026/09/4da3a0bb-69bc-480b-982f-1666ea067969.webp)

The four numbers in every breadth reading, filled with the Aug 28, 12:00 UTC minute. Breadth ships as value_pct; the counts and coverage_ratio ride on every reading.

Every snapshot also carries the raw counts behind the percentage, so you can check the math yourself.

## Why market breadth is an edge, and its first eight days on Hyperliquid

Every equities desk watches market breadth: count how much of the market confirms a move instead of trusting the index. The same count works in crypto, someone just has to keep score on hundreds of coins every minute. This endpoint keeps the score for Hyperliquid and serves it as one number.

The VWAP anchor is why the count carries signal. A coin above its day's average price means the day's buyers are in profit, and traders sitting on wins behave differently from traders trapped under water. Summed across the venue, that is a read on positioning, not just price: is the tape winning together, or are the majors dragging the index while everything else drowns. The first eight days on record, day by day:

| Day (UTC) | First | Low | High | Last |
| --- | --- | --- | --- | --- |
| Aug 24 | 54.2% | 3.9% | 92.3% | 37.5% |
| **Aug 25** | **21.9%** | **1.7%** | **97.8%** | **6.1%** |
| Aug 26 | 16.3% | 3.9% | 96.0% | 91.4% |
| Aug 27 | 48.2% | 5.6% | 95.6% | 59.3% |
| **Aug 28** | **40.8%** | **1.1%** | **96.0%** | **22.4%** |
| Aug 29 | 45.0% | 11.4% | 81.6% | 63.1% |
| Aug 30 | 44.2% | 6.2% | 85.5% | 8.6% |
| Aug 31 (to 17:40) | 34.3% | 21.4% | 93.6% | 61.7% |

*First and last are each day's first and last reading; the first minute of every day is empty by design (see the quirks section).*

## How breadth catches selloffs the BTC chart hides

The clearest early example of the Bitcoin chart and the rest of the market disagreeing. Bitcoin opened August 28 near its weekly high and slipped 0.64% overnight. Nothing you would wake up for.

Breadth told it differently. At 02:32 UTC, 176 of 178 coins were under water. Almost everyone long anything that night was losing while the BTC chart read flat.

![Two panels from the same moment, August 28 2026 at 02:32 UTC: the left shows BTC within a plus or minus 2 percent band, down 0.3% on its session; the right shows all 178 eligible Hyperliquid coins as dots, 176 red and 2 green.](https://api.0xarchive.io/cms-assets/2026/09/7c520426-59ec-4804-b802-f9716a01aede.webp)

The same moment, two views. BTC sat 0.3% below its session open while 176 of 178 coins were under water. The index chart said nothing; the tape said everything.

## What to know before you trade on it

Three things about how it behaves. Read them before wiring it into a strategy.

**1. The day resets at 00:00 UTC, and the number goes wild for a few hours.** A fresh day means a fresh average built on minutes of trading, so tiny moves flip coins from green to red. The first minute of each day is empty, nothing has traded yet. None of this is a market signal. It is just the clock.

![Bar chart of the average one-minute change in Hyperliquid breadth by hour of the UTC session: about 5.1 points in hour zero, decaying to about 0.9 points by hour 23.](https://api.0xarchive.io/cms-assets/2026/09/ad6fdd57-627a-4c62-b088-24ce718512eb.webp)

Hyperliquid breadth after the daily reset, hour by hour. Average one-minute change, in points, raw 1-minute snapshots Aug 24 to 31. In the session's first hour the reading moves 5.1 points per minute on average; by the last hour, 0.9. Same endpoint, six times the noise, purely because the day is young.

**2. Zoomed-out views show the last reading, never an average.** Ask for `interval=15m` and each row is the final snapshot of its window. Averaging would mix readings that counted different coins.

**3. The coin count breathes.** Coins drop out when they go quiet or their price goes stale, and they come back when they trade again. Every row says exactly how many were counted and why the rest were not, so nothing shifts under you silently.

## Calling the breadth endpoint: parameters and response

One route, key in the `X-API-Key` header. Omit `interval` for the raw one-minute snapshots; page through history with `cursor` from each response's `meta.next_cursor`.

| Param | Values | Behavior |
| --- | --- | --- |
| `start` / `end` | epoch ms, inclusive | window; defaults to the last 24h |
| `interval` | 5m, 15m, 30m, 1h, 4h, 1d | zoom out; each row is the last reading of its window, omit for the raw minute feed |
| `limit` | 1–1000, default 100 | rows per page |
| `cursor` | from `meta.next_cursor` | pagination through long windows |

To put price next to breadth, the [candles endpoint](https://docs.0xarchive.io/api-reference/hyperliquid--candles/get-hyperliquid-ohlcv-candles) serves OHLCV for any Hyperliquid perp with the same auth and envelope; every BTC number in this article came from it. The rest of the venue's surfaces live on the [Hyperliquid hub](https://0xarchive.io/hyperliquid).

## Run this analysis from an agent

Every number and chart in this article came from public endpoints an agent can call. 0xArchive ships an [MCP server](https://docs.0xarchive.io/mcp-server), so Claude and other AI agents can query the same breadth and candle surfaces in plain language. There is a [Claude Code skill](https://docs.0xarchive.io/claude-code-skill) for terminal workflows and an [agentic gateway](https://docs.0xarchive.io/agentic-gateway) for agents that pay per call. Start with the [agent surfaces overview](https://docs.0xarchive.io/agent-surfaces) or the guide to [replayable market data for MCP, CLI and agent workflows](https://0xarchive.io/resources/market-data-guides/replayable-market-data-for-mcp-cli-and-agent-workflows).

## Route references

Use the [market breadth reference](https://docs.0xarchive.io/rest-api/breadth) for the breadth route and the [Candles reference](https://docs.0xarchive.io/rest-api/candles) for the OHLCV that pairs price with it.
