TourScanner

TourScanner AI guide

How to use the TourScanner API: search tours and activities, check live availability, and book them. It also covers the MCP server, if you want an AI agent to do the same thing.

It's a REST API (JSON over HTTPS, OpenAPI 3.1) for tours, activities and attractions worldwide. The catalog is about a million activities from 14 providers, behind one set of endpoints. This repo is the practical side of the docs: what to call, in what order, and the mistakes that cost people an afternoon.

Reference docs live at tourscanner.ai/docs, and the machine-readable spec is at tourscanner.ai/openapi.json.

Get a key

Keys are issued by hand. Email api@tourscanner.ai with what you're building and which cities matter to you. Send it in the X-API-Key header on every request. Without one you get a 401.

export TOURSCANNER_API_KEY=your_key

First request

curl -s "https://tourscanner.ai/api/search/activities?city=rome&q=colosseum&limit=3" \

-H "X-API-Key: $TOURSCANNER_API_KEY"

You get back activities, plus total, page and some facets. Each activity has an id, a name, a rating, and a price of the form { "currency": "EUR", "price": 5400 }.

Prices are integers in minor units, so 5400 is 54.00. This applies to the min_price and max_price filters too.

The booking flow

Five calls, in this order:

1. GET /api/search/activities to find something.
2. POST /api/availability/slots for the real slots and prices on a date.
3. POST /api/booking/options for the ticket variants and booking questions.
4. POST /api/booking/hold reserves the slot and returns a Stripe checkoutUrl. The card is authorized, not charged.
5. POST /api/booking/confirm after the customer pays. This confirms with the supplier and captures the payment.

Details and request bodies are in docs/booking.md. A runnable version of steps 1 to 4 is in examples/node/book.mjs.

Examples

Node, Python, Ruby, Go and curl. Each does the same three things: search, check availability, and run the booking flow up to the Stripe link. None needs a package beyond the language's standard library (Node 18 or newer).

Run the Go ones from examples/go. The curl scripts are in examples/curl.

They read your key from TOURSCANNER_API_KEY. Set TOURSCANNER_BASE_URL to point them at a different host. Run book without OPTION_CODE first: it prints the options and stops, so you can pick a code. On the production host a full book run places a real hold and creates a real Stripe checkout.

Missing your language? The API is plain JSON over HTTPS, so any HTTP client works. The OpenAPI spec above will generate a client for most languages.

For AI agents

There's a remote MCP server at https://tourscanner.ai/api/mcp. It exposes 12 tools covering search, availability, checkout links, and booking status. Setup for Claude, Cursor, VS Code and others is in docs/mcp.md.

Things that trip people up

• Cents, not euros. Every price field is in minor units.
• `productOptionCode` comes from `booking/options`. The hold fails without it, and the codes differ per activity.
• `adults` is required in passengers, and it has to be at least 1.
• Phone numbers need the country code, like +442079460000. Anything else is rejected.
• Stripe sessions expire after 30 minutes. After that the hold is released.
• Check availability right before booking. Search results come from our catalog, and slots come live from the supplier. They can disagree.
• Not every provider books in-house. For the others you hand the traveller off to the partner instead. Adding providers=2,3,7 to a search limits it to the ones we book directly. The MCP get_activity tool reports this per activity as bookableByUs.
• Rate limits return `429` with a Retry-After header. Honor it.

Environments

The production host places real holds and real Stripe checkouts. If you want a sandbox on provider test rails, ask for one when you get your key.
