For Agents

Get bookable seat counts per booking class for flight segments. Agents POST to /shopping/availability/flight-availabilities to check class-by-class capacity before constructing a ticket.

Install Jentic One Beta

Connect the Flight Availabilities Search to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Flight Availabilities Search, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

View OpenAPI Document

The Amadeus Flight Availabilities Search API returns seat availability per booking class for one or more origin-destination pairs and dates. The single POST to /shopping/availability/flight-availabilities is closer to a GDS availability call than to a fare search — it gives the number of bookable seats per Reservation Booking Designator on each flight segment, which is what travel agencies and OTAs need to construct multi-segment tickets without overselling. Use this when a fare-only search is not enough and you need raw availability per cabin class.

Use Cases

Patterns agents use Flight Availabilities Search API for, with concrete tasks.

★ Travel Agency Ticket Construction

Agencies issuing complex itineraries need raw availability per booking class on each segment, not just a list of fare offers. The /shopping/availability/flight-availabilities endpoint returns the number of seats open in each Reservation Booking Designator, which lets the agent assemble a multi-segment ticket that will actually price and book without surprise sold-out errors at confirmation.

POST a request for JFK to LHR on 2026-09-15 plus LHR to BCN on 2026-09-18 and return the seat counts per booking class for each leg.

Group Travel Capacity Check

When booking a group of 8 travellers in a specific cabin class, a fare-search response that simply says 'available' is not enough — you need at least 8 seats open in the same RBD. Calling Flight Availabilities Search confirms the class-level capacity before the group sales agent commits, removing the back-and-forth that happens when the priced offer fails at the booking step.

Confirm at least 8 seats are open in J class on the LH segment between FRA and JFK for the group's travel date.

Fare Construction with Class Control

Sophisticated travel sellers construct fares manually by selecting booking classes that price together favourably. Flight Availabilities Search exposes those classes directly, so a pricing engine can pick the right class per segment instead of relying on whatever class the public Flight Offers Search returns.

Identify the lowest open RBD for each segment in the proposed itinerary and construct a fare around those classes.

Agent-Driven Availability Audit

An AI agent supporting a travel desk can answer 'is there a J seat on flight LH 400 next Tuesday?' by calling availability search directly. Through Jentic the agent searches for 'check seat availability per booking class', loads the schema, runs the POST, and returns a yes/no answer with the exact seat count from the response.

Use Jentic to call the flight-availabilities operation and report whether at least one J-class seat is open on the user's chosen flight.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Amadeus client credentials are stored encrypted in the Jentic vault (MAXsystem). Jentic exchanges them for a short-lived bearer token at execution time so the raw secret never enters agent context.

Intent-based discovery

Agents search Jentic for 'check seat availability per booking class' and Jentic returns the /shopping/availability/flight-availabilities operation with its input schema, removing the need to read Amadeus self-service docs first.

Time to first call

Direct Amadeus integration: 1-2 days to wire OAuth, build the request shape, and parse RBD responses. Through Jentic: under one hour — search, load, execute.

FAQs

Specific to using Flight Availabilities Search API through Jentic.

What authentication does the Flight Availabilities Search API use?

The API uses the Amadeus OAuth 2.0 client-credentials flow. Exchange API key and secret at the Amadeus token endpoint and send the bearer token on the /shopping/availability/flight-availabilities POST. Jentic stores the credentials in the encrypted vault and refreshes the token automatically.

How is this different from Flight Offers Search?

Flight Offers Search returns priced offers with a publicly bookable fare. Flight Availabilities Search returns raw per-class seat counts (per Reservation Booking Designator) for the segments you specify, without pricing them. Use the availability call when you need to confirm class capacity before constructing a ticket.

What are the rate limits for the Flight Availabilities Search API?

Rate limits are not declared in the OpenAPI spec and depend on the Amadeus contract tier. Availability calls are heavier than reference-data lookups, so expect a tighter per-second cap and use targeted queries rather than scanning a whole calendar of dates.

How do I check class-level availability through Jentic?

Run pip install jentic, then use the search query 'check seat availability per booking class'. Jentic returns the /shopping/availability/flight-availabilities operation, you load the schema, supply origin, destination, date, and traveller counts, and execute. The response gives RBD seat counts per segment.

Can I search availability across multiple legs in one call?

Yes. The request body accepts an array of originDestinations so a single POST can return availability for an outbound and a return, or for a multi-segment itinerary. Each leg's RBDs are returned independently.

Is the Flight Availabilities Search API free?

Amadeus self-service APIs include a free test environment with quota limits and a paid production tier. Availability calls in production are contracted and pricing scales with transaction volume — confirm current rates in the Amadeus self-service developer portal.
