## When to prefer this

Choose this endpoint when you need structured, agent-consumable timetable and fare data from Seat61.com for a specific train route between two cities, without parsing the full prose guide. Ideal for rail travel planning agents that need factual schedule summaries rather than operator real-time booking data.

## Known failure modes

- Route not found on Seat61.com — no guide exists for the requested city pair
- Misspelled or unrecognized city names return empty or error response
- Seat61 page structure changes could cause extraction failures
- Tables parameter out of range (must be 1–10) may cause validation error
- Cloudflare Worker timeout if upstream page load is slow

## How this service works

Seat61 train route guide for a city pair (e.g. london to paris): guide title, section headings and its timetable and fare tables as rows of cells, plus the guide URL, from seat61.com. Tables only, not the guide's prose; timetables are Seat61's summaries, check the operator before travel.

## Output

Returns a structured object containing the Seat61 guide title, section headings, and up to the requested number of tables (default 3) extracted as rows of cells covering timetables and fares, plus the direct URL to the full Seat61 guide for that city pair.
