Government counts of who crossed the border: Hong Kong's daily arrivals at every land, sea and air control point, from the Immigration Department, and Singapore's monthly visitor arrivals by place of residence, from the Singapore Tourism Board.

Hong Kong's file is the fastest read on Chinese outbound travel any government publishes, yesterday's number on the site today: Mainland visitor arrivals for Hong Kong retail, jewelry and hotels, and arrivals through the two Macau gateways. Singapore's table front-runs Marina Bay Sands' and Resorts World Sentosa's visitation, the airline and the hotel trusts, split by the source markets that move it.

Neither names a company, which is why this is a market-level dataset: it is the demand the listed operators report against.

Available Data Points:

• Period Date: The period the value describes — what the number is about (the valid clock).
• Published At: When the value first became knowable — when the publisher released it (the knowledge clock). Filter on this for anything where look-ahead bias would matter.
• Value: The numeric value, where the series has one.
• Value Text: The textual value, for categorical series such as a trial's status or phase.
• Unit: Unit of the value, e.g. vehicles, percent, USD.
• Value Type: number, percent, currency, count or text.
• Frequency: How often the publisher releases the series.
• Market: The market the reading describes — an ISO-3166 alpha-2 code (DE), a sub-national one (US-CA), a supranational aggregate (EA, EU) or GLOBAL.
• Series Slug: Which series the reading belongs to. Unique within a publisher, not globally.
• Series Name: Human-readable name of the series.
• Source Slug: Publisher/feed identifier, e.g. kba_registrations.
• Source Name: Human-readable name of the publisher or feed.
• Publisher: Who publishes the underlying data.
• Entity Ref: The publisher's own identifier for what the reading is about — a manufacturer name, a securitisation trust, a reactor unit, a country code. Kept so any value can be traced back to the row it was parsed from.

This dataset describes a market, not a company

Every reading here is about a country or a whole market, so there is no ticker in the path and no instrument in the response envelope. That is deliberate: attaching a national print to a listing would be a claim the data does not support. Read it as the context the company-level endpoints are measured against.

Coverage

Hong Kong: daily from 1 January 2021, the morning after the day counted; arrivals only. The first two years sit inside border restrictions and are a different market rather than a low baseline. Singapore: monthly since January 2008, about a month after the month closes; the total and the five largest source markets (China, Indonesia, India, Malaysia and Australia).

What to look for

The Macau gateway series is only the Hong Kong leg of Macau travel. Most Mainland visitors to Macau cross at Gongbei and never appear here, so read its direction and weekly shape, not its level.

Both are strongly seasonal around Lunar New Year and the Chinese golden weeks, which move between months. Compare with the same period a year earlier, and read Hong Kong's daily data as rolling weeks.

Singapore counts visitors by where they live, not by nationality, and the mix matters more than the total: a Chinese visitor spends multiples of a Malaysian day-tripper.

Two dates on every reading, and the difference is the edge

periodDate is what the number is about. publishedAt is when it first became knowable. The gap between them is the whole point of alternative data — and it is also the trap. A Form 10-D describing July is filed in mid-August, so a backtest that treats the period as the knowledge date reads a document six weeks before it existed.

from_date and to_date filter on periodDate, because that is the axis you plot against. Join on publishedAt when you are joining against returns.

Filtering: one market or all of them

Called with no filters, the endpoint returns every series in the dataset, for every market ORTEX covers it in. Each row names its own market, seriesSlug and sourceSlug, so a single request is enough to chart the whole dataset.

Narrow it with any combination of market (one market), series (one measure) and source (one publisher). Filter values that are each valid but select nothing together return 400 invalidSelection rather than a misleading empty result.

A series slug identifies a series within a publisher, not globally

unemployment_rate is published under that exact slug by the US Bureau of Labor Statistics, the UK Office for National Statistics and Statistics Canada. Where a slug names more than one series in a dataset, passing it alone returns 400 invalidSeries listing the alternatives — pair it with market or source. ORTEX would rather refuse than hand you one country's print labelled as another's.

How much history there is

Several of these publishers overwrite their own pages and keep no archive. Where that is so, the series begins on the day ORTEX started capturing it and lengthens from there — nobody, including the publisher, can supply the days before that. Everything ORTEX has ever fetched is archived on capture, so the series only ever grows.

Try it out! You can test the API with the trial key TEST. Simply include it in your request headers; either here, or add the header "Ortex-Api-Key": "TEST" to your http request.

Trial key restrictions: Trial keys may be limited to a specific date range and set of regions. Requests outside the allowed regions or entirely outside the allowed date range are rejected; a date window that partially overlaps the allowed range is trimmed to it, reported in meta.restriction.
