Add group trip planning to your product.

API access for travel partners, booking platforms, and productivity tools.

One endpoint

Three trip cards from a single API call.

// Create a trip research request
POST /api/v1/research
{
  "input": "fall weekend, 3 families, cabins near lake, $1500/family",
  "households": 3
}
// → Returns 3 trip cards: { destination, lodging[], activities[],
//   costPerHousehold, reasoning }
// → Returns in ~5 minutes

Platform

What’s coming.

Data

Trip data API.

Read trip details, dates, destinations, household composition, and itinerary state. Build integrations that know where a group is going and when — with household-level permissions, not individual-level.

Intelligence

Otto research API.

Trigger Otto research programmatically for your users. Pass constraints, get back three structured trip cards with lodging, activities, and cost breakdowns. The same two-phase engine that powers the product, available as an endpoint.

Events

Webhook events.

Get notified when trips are created, dates are locked, lodging is selected, and trips are completed. Build workflows that respond to trip lifecycle events without polling.

Identity

OAuth for households.

Let users connect their Longtable household to your app. Household-scoped authorization means the partner who plans and the partner who shows up both get the right level of access.

Timeline

API beta opens Q3 2026.

Early access for design partners. If you’re building something that touches group travel — booking, activities, calendar, expenses — and want to integrate with household-scoped trip data, we want to talk.
