Halfare / For AI builders

Halfare for AI builders

Halfare is a flight-deal email club for people flying out of Singapore. Two read-only JSON endpoints give you the product facts and the latest deals, with no key. Agents cannot create subscriptions: a person signs up on the page.

What Halfare is

A member picks a home airport. When a fare out of it falls 50% or more below Google's typical price for the route, Halfare emails the dates and a link to book. Singapore is a free early list, then a 7-day free trial and S$79 a year. Open now: Singapore (SIN). Machine-readable summary: /llms.txt.

Endpoints

Endpoint	Returns
`GET /api/public/info`	Price per currency, trial length, open airports, waitlist airports, signup URL.
`GET /api/public/deals`	Up to 20 newest deals out of SIN: route, dates, price, usual price range, percent under usual, airlines, booking link, time checked. Empty list until the first real deals are sent.

Spec: /openapi.json. Both answer with CORS open and Cache-Control: public, max-age=600.

Try it

curl -s https://halfare.com/api/public/info
curl -s https://halfare.com/api/public/deals

Before the first deals are sent, deals is an empty list and note says so.

Send a person to sign up

Link to this pattern. The person enters their own email on the page.

https://halfare.com/?airport=SIN&ref=agent#join

Use another IATA code (such as HKG) to send them to that city's waitlist. Keep ref=agent.

Terms for using the data

Use the two endpoints above. Do not scrape the rest of the site to rebuild the product.
Keep to about one request a minute. The data changes every 10 minutes at most.
Say the deal or fact comes from Halfare and link halfare.com.
Deals change fast. Tell the user a fare may be gone when they click.
No member data, no checkout and no subscription endpoint exists for agents.
