Custom GPT hotels — add 1.7M-hotel booking to your ChatGPT GPT

Paste one URL into your custom GPT's Actions tab. Now it can search 1.7M hotels and return booking deeplinks — with your partner key on every booking.

What this is

custom-gpt-hotels: the OpenAPI manifest is at https://swarm.impt.io/api/gpt/openapi.json. Use this URL in ChatGPT Builder → Configure → Actions → Import.

The OpenAPI manifest

URL: https://swarm.impt.io/api/gpt/openapi.json

It defines four operations: searchHotels, createIntent, quote, deeplink. Same as the MCP server — just exposed in OpenAPI 3.1 instead of MCP.

Use cases

Why this matters for SEO & AI search

OpenAI's GPT Store is becoming a discovery surface for the next billion travel queries. Owning the booking action inside a popular custom GPT is the new equivalent of ranking #1 for "hotels in <city>".

FAQ

Does this work in ChatGPT Plus / Team / Enterprise?

Yes — custom GPT actions are available on all paid tiers.

Will users see my partner key?

No — it's set as an authentication header in the GPT Builder config. Users don't see headers.

What does it cost?

€0 setup, €0 monthly. We pay you 5% on every confirmed booking your link drives.

How long is the cookie?

90 days. Click today, book in 89 days — you still earn the commission.

How is commission paid?

Monthly. Stripe / Wise / IBAN / PayPal / IMPT card / IMPT token. €50 minimum payout. Live tracker at swarm.impt.io/partners/dashboard.

Do my followers pay more?

No — same price as Booking.com or direct. Plus 1 tonne UN-verified CO₂ retired on Ethereum per booking. They lose nothing; you earn 5%.

How big is the inventory?

1.7M hotels in 195 countries via the IMPT.io hotel API. Live availability and pricing.

Is the widget really open source?

Yes — MIT licensed on GitHub. Fork it, self-host the front-end, hit our API for inventory and attribution.

Can I see real-time stats?

Yes — partner dashboard at swarm.impt.io/partners/dashboard shows clicks, bookings, earned, payable.

What's the catch?

There isn't one. We share 5 percentage points of the hotel commission with you and burn 1 t CO₂. Climate-positive affiliate, no upsell, no retainer.
