Version of 10 November 2026. They apply to every vendor account; using the live key (nz_live_…) means accepting them. English translation of the French terms, which prevail in case of difference (article 12).
1. Parties and purpose
These terms bind CLOUDCORE, a French simplified joint-stock company (SASU) with a share capital of €1,000, registered with the Versailles Trade Registry under number 820 738 714, 2 B chemin du Vivier, 78310 Maurepas, France, publisher of Nestiz ("Nestiz"), and the company that opens a vendor account ("the Vendor").
They govern access to the Nestiz application programming interface ("the API"), which lets the Vendor connect the listings managed in its own software to booking platforms (Airbnb, Booking.com, Vrbo and the other platforms listed by GET /v1/platforms): sending prices, availability and stay rules, and receiving bookings.
The Vendor acts for the purposes of its business. The Vendor's customers (owners, managers, hoteliers: "the End Customers") are not parties to the contract. A hotel that connects its own software is both the Vendor and its own End Customer.
2. Access to the API
- Test mode (
nz_test_…): free, with no time limit. Nothing is sent to the platforms. - Live mode (
nz_live_…): opened by Nestiz, vendor by vendor, once the integration has been checked (GET /v1/checklist). Nestiz may refuse it without giving reasons as long as no subscription has started. - The API is used only as described in its documentation (nestiz.fr/editeurs/docs). The Vendor does not try to reach Nestiz's providers directly, nor to get around the limits (120 calls per minute per key, listing cap of its account).
- Keys are personal and confidential. The Vendor keeps them on its servers, never in an application installed at its End Customers, and informs Nestiz without delay if a key leaks: the key is then revoked.
3. Vendor's obligations
- Obtain each End Customer's consent before connecting their platform accounts, and give them the information they need (prices, terms, processing of their data).
- Provide first-level support to its End Customers: Nestiz supports the Vendor, not its End Customers.
- Send accurate and up-to-date data (prices, availability); the consequences of an input error or a wrong update sent by the Vendor (overbooking, price too low) remain its responsibility.
- Comply with the booking platforms' terms and with the regulations that apply to its End Customers' rentals.
4. Prices and billing
Monthly subscription, charged in advance on the 28th of each month, with no minimum amount, prices excluding taxes (French VAT added, except for a Vendor established outside the European Union):
| Price per month, excl. VAT | |
|---|---|
| Rental | by brackets, messaging included: $4 up to 10 listings, $3.50 from 11 to 30, $2 from 31 to 50, $1.50 from 51 to 80, $1 from 81 to 1,999, $0.95 from 2,000 to 3,999, $0.90 from 4,000 to 6,999, $0.80 above |
| Property (hotel, guest house, hostel, campground…) | by brackets, whatever its number of rooms: $17 up to 5 properties, $14 from 6 to 10, $10 from 11 to 20, $7 from 21 to 499, $6 from 500 to 999, $5 from 1,000 to 1,999, $4 above |
| Guest messaging and reviews for a property (option) | $7 per property that takes it |
| Property with more than 20 room types | $1 per room type over 20, $7 at most per property |
- Brackets: only the units above a threshold move to the next price.
- Cap: the bill never exceeds $115 + $1 per rental + $7 per property, with property messaging and room types over 20 on top (above 1,999 rentals or 499 properties: the per-unit prices of the brackets above).
- A property groups rooms at a single address (same property on hotel platforms, same Airbnb listing address). A room type located elsewhere, or whose address no platform gives, is billed as a rental; an annex at the same place can be approved by Nestiz at the Vendor's request.
- Only live mode is billed, and only the listings and properties connected to at least one platform. The next month's amount is based on the listings connected on the 28th, full price, no proration; a listing connected after the 28th is billed from the following 28th.
- Ten rate plans at most per listing. A listing connected twice to the same platform is billed €1 more per month and per duplicate connection, after the Vendor has been informed.
- Prices in US dollars, charged in euros: the month's amount is converted at the European Central Bank reference rate recorded the day before the charge, shown on the invoice.
- Vendor subscribed before 10 November 2026: the euro price list and the currency of its subscription remain its own; the price list above applies instead as soon as it saves at least 5%.
- No trial in live mode: the free test mode serves as the trial. Payment is by card (Stripe). Once live mode is opened, it works as soon as the Vendor has saved its card, with nothing charged that day; the amount is then charged automatically on each 28th (article 6 if the payment fails).
- Any price increase is announced by email at least 90 days before it takes effect; a Vendor that refuses it may terminate free of charge before that date.
- Vendor established outside the European Union: prices without French VAT, with a reverse-charge or exemption notice on the invoice.
5. Availability
Nestiz targets an API availability of 99.5% per month, excluding announced maintenance. Syncing with the platforms is instant, with a delay of 0 to 30 seconds depending on the platform; Nestiz guarantees neither the time each platform takes to apply an update, nor the availability of the platforms themselves.
6. Suspension
Nestiz may suspend a key or the Vendor's account, after an email at each step (without notice in an emergency):
- failed payment: nothing changes until the last day of the month; if still unpaid that day, the platform connections are removed (the End Customers go back to manual management) and the live key is refused. An updated payment method restarts the subscription;
- abusive use of the API (repeated overrun of the limits, obviously wrong updates, attempts to get around the rules);
- a risk to the security of the service, the platforms or other customers.
The suspension ends as soon as its cause has gone. During a suspension, the platforms no longer receive updates: the Vendor informs its End Customers.
7. Liability
Nestiz uses reasonable means to keep the API reliable. Except in case of gross negligence or fraud, its liability is limited to the amount paid by the Vendor over the last three months, and does not cover indirect damage (loss of bookings, revenue or customers). Nestiz is not liable for outages, delays or errors caused by the booking platforms, nor for the data sent by the Vendor.
Neither party is liable for a failure caused by force majeure within the meaning of article 1218 of the French Civil Code.
8. Term and termination
No minimum term. Either party may end the contract at any time, the Vendor from its vendor space ("Stop subscription") or by email; termination takes effect at the end of the month already billed, with no refund of the current month, and nothing more is charged. The platform connections are then removed; the listings stay on the platforms, under the End Customers' control. The Vendor exports what it needs before that date.
9. Personal data
- For the data of End Customers and their guests, the Vendor is the controller and Nestiz the processor (article 28 of the GDPR): Nestiz processes this data only to run the API, on the Vendor's instructions, and keeps it confidential.
- Nestiz does not solicit the Vendor's End Customers and never uses their data for commercial purposes.
- For some platforms, Nestiz uses certified connectivity providers as sub-processors, and Stripe for billing the Vendor. The Vendor accepts this and may object to any new sub-processor announced.
- Hosting in France. Log of API calls kept for the duration of the contract, for support and security. Platform credentials (passwords, keys) kept encrypted only while a connection is being set up, never sent back.
- When the contract ends, the Vendor's data, log included, is deleted within 30 days, unless the law requires it to be kept.
- Nestiz informs the Vendor within 48 hours of any personal data breach that concerns it.
10. Connectivity provider
For some platforms, the connection relies on third-party connectivity providers. If one of them stops or changes its service, Nestiz may adapt the API or end the contract with at least fifteen days' notice to the Vendor, or as soon as it learns of it if the delay is shorter; the part already paid for the following period is refunded.
11. Ownership
The API and Nestiz remain the property of CLOUDCORE. The Vendor receives a non-exclusive, non-transferable right of use for the duration of the contract. The data sent by the Vendor belongs to it. The Vendor may present the platform connection under its own brand, without naming Nestiz.
12. Assignment, changes, governing law
- CLOUDCORE may transfer the contract to any company that takes over the operation of Nestiz (articles 1216 and 1216-1 of the French Civil Code), after an email to the Vendor thirty days before.
- Nestiz may change these terms by informing the Vendor by email thirty days before (90 days for prices, article 4).
- These terms exist in French and in English; in case of difference, the French version prevails.
- French law. Failing an amicable settlement, any dispute falls under the competent courts of the place of CLOUDCORE's registered office.
