Here’s the current picture based on the latest internal docs and the 2025 GRATIS & API client list.

1. Main VD APIs in use

Venue Directory exposes these core APIs to customers:

  • Venue API – real‑time/sync access to venue data; used by external sites and apps to power search and profiles.
  • Instant Book / IBK APIs – instant‑booking rate search & inventory; used by MEC, Venue API, Small Meetings and agent sites to process online bookings.
  • Enquiry / GRATIS APIs– APIs around enquiries and bookings in GRATIS, including:
    • Enquiry/Booking Data Feed (“API Data Feed”, “API Enquiry Data Feed”, “API Data Feed – Instant Book”) – pulls enquiry/booking data from GRATIS for agents/CRMs/finance.
    • Gratis API / Booking Change Notification – push notifications of booking changes and APIs to retrieve the details.

2. “Venue API integrations” (non‑GRATIS data customers)

These are called out explicitly as Venue API integrations (do not use GRATIS but take TVD Venue API data and send RFP data back):

  • Agiito – uses Venue API + IBK API (instant book). Also tied to Clarity (w/ GRATIS).
  • Conference Care – listed under Venue API integrations; takes venue data and returns RFP data via API.
  • HTS (Hotel & Travel Solutions) – Venue API integration.
  • Inntel – Venue API integration plus API Data Feed / Instant Book API products in the 2025 sheet.
  • Top Banana – Venue API integration; also tagged as API Client in the GRATIS grid and has a 3‑year API contract in the commercial sheet.

These are your core “Venue API + IBK” data customers.
