Live on Testnet

Travel infrastructure for the agentic era.

Bookings, prepaid escrow, USDC settlement, and trip support — in one persistent thread.

Four ways in

One engine. Every entry point.

Mainnet wave

Get in line for production.

Agencies, companies, and AI builders go live in waves. Reserve your spot for prepaid budgets, MCP tools, and white-label ops.

The secure waitlist is still negotiating the local development session.

Route intelligence

One request. One auditable route.

Intent, policy, approvals, inventory, escrow, support, and reconciliation stay attached to the same trip record.

Where travel starts

Same engine. Every entry point.

Travel begins in messy places — a chat, an agency desk, a finance approval, an LLM. Sendero gives each one the same booking, escrow, settlement, and support engine.

Individual traveler

Book from the thread already open.

Start in WhatsApp or web, compare real options, claim a prepaid budget, keep the same agent for changes and support.

Travel agency

A booking link that runs like a staffed counter.

You keep the customer. Sendero handles quote, policy, hold, ticketing, payment, invoice, and trip support.

Corporate travel

Prepay. Keep policy and audit aligned.

Issue prepaid guest links, route exceptions to Slack, cap tenant spend, reconcile every action to the right trip and invoice.

AI agents

Let another agent call the back office.

Discoverable via llms.txt and MCP. Tools for search, prefunding, reservation, settlement, refunds, and invoicing — priced per call.

A trip agent that remembers

Preferences, passport, budget, dates, receipts, and changes — all in one conversation.

White-label operations

Bring your WhatsApp number and customer relationship. We bring the booking, escrow, and support engine.

Spend under control

Policy, approvals, prepaid guest budgets, caps, invoices, audit — built into the trip.

Travel tools for agents

MCP discovery, llms.txt, priced tool calls, and named workflows. Delegate real travel work safely.

Visual system

A travel OS should look inspectable.

Maps, stamps, tickets, receipts, and route marks — because the product is custody of intent: who asked, who approved, what was held, what settled.

Custody trail

Every action leaves a postcard.

Locked requests, tagged context, approval stamps, settlement marks, and final records. Invisible agent work, made visible.

01SealSecure the request

The trip starts as a locked instruction, not a loose chat promise.
