Install Jentic One Beta

Connect the Flight Check-in Links to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Flight Check-in Links, 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.

Capabilities

For Agents

Return the official online check-in URL for an airline by IATA code. Agents call /reference-data/urls/checkin-links to deep-link travellers directly into web check-in.

Use for: I want to get the online check-in URL for British Airways, Find the check-in link for Lufthansa in German, Search for the check-in URL for the carrier on the user's itinerary, Get the web check-in entry point for American Airlines

Not supported: Does not perform check-in, return seat maps, or issue boarding passes - use only to retrieve the carrier's official online check-in URL.

Use Cases

Patterns agents use Flight Check-in Links API for, with concrete tasks.

★ Trip-Detail Deep Links

Travel apps and itinerary screens want a one-tap 'Check in now' button that goes to the carrier's official web check-in page. The /reference-data/urls/checkin-links endpoint returns that URL given the carrier IATA code, so the app can deep-link the traveller directly without the user hunting for the right airline.com URL. The lookup is cheap enough to call inline when rendering the trip detail.

Call /reference-data/urls/checkin-links with airlineCode=BA and return the official check-in URL.

Pre-Flight Reminder Emails

Itinerary platforms send a 'time to check in' email roughly 24 hours before departure. To make the call to action useful, the email needs the carrier's actual check-in URL, not a generic search link. The check-in links endpoint provides exactly that, keyed by IATA code, so the reminder email service can populate the link at send time without maintaining a list of carrier URLs internally.

For every itinerary departing in 24 hours, fetch the check-in URL for the operating carrier and inject it into the reminder email.

Localised Travel App Experience

Travel apps with a German or French audience can request the localised check-in URL by passing the language parameter. The carrier returns the right locale variant of its check-in page, which gives travellers a smoother handoff than the default English page. Combine with the user's app language setting to pick the right locale automatically.

Fetch the German-language check-in URL for LH and use it as the deep link for German-locale users.

Agent Departure Coordinator

An AI travel assistant nudging a user toward their flight can call check-in links automatically once it has the operating carrier from the itinerary. Through Jentic the agent searches for 'get airline online check-in url', loads the schema, executes the lookup, and returns the URL to the user with a friendly reminder. No carrier-URL table to maintain in the agent's prompt.

Use Jentic to fetch the check-in URL for the carrier on the user's itinerary and return it with a 'check in opens at' message.

Why Jentic?

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

Credential isolation

Your Amadeus client_id and client_secret are stored once, encrypted, by your own Jentic One instance, which performs the client_credentials exchange and injects a fresh bearer token at execution time. The raw secret never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'get the online check-in URL for British Airways', and Jentic returns the /reference-data/urls/checkin-links operation with its input schema so the agent supplies the airline code without scanning the Amadeus docs.

Time to first call

FAQs

Specific to using Flight Check-in Links API through Jentic.

What authentication does the Flight Check-in Links 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 /reference-data/urls/checkin-links request. Jentic stores the credentials in the encrypted vault and refreshes the token automatically.

Does the response include localised URLs?

Yes, where the carrier supports multiple languages. Pass a language parameter on the request and the API returns the locale-appropriate check-in URL when the carrier publishes one. If only a default URL exists, that is what the API returns.

What are the rate limits for the Flight Check-in Links API?

Rate limits are not declared in the OpenAPI spec and depend on the Amadeus contract tier. The endpoint is read-only and the response is cacheable for hours, so cache per IATA code and language to stay well under the per-second cap on production traffic.

How do I add a check-in link through Jentic?

Run pip install jentic, then use the search query 'get airline online check-in url'. Jentic returns the /reference-data/urls/checkin-links operation, you load the schema, supply airlineCode and language, and execute. The URL drops straight into your trip-detail UI or reminder email.

Which carrier should I pass for a code-share flight?

Pass the operating carrier's IATA code, not the marketing carrier - passengers check in with the airline that actually operates the aircraft. The operating carrier is part of the flight segment data returned by Flight Offers Search and similar endpoints.

Is the Flight Check-in Links API free?

Amadeus self-service APIs include a free test environment with quota limits and a paid production tier. Production access is contracted with Amadeus and pricing scales with transaction volume - check current rates in the developer portal.

Can I limit what my agent is allowed to do with the Amadeus Flight Check-in Links API?

Yes. Because you run Jentic One yourself, your own rules decide which operations and credentials the agent may use, and scoping here is by operation since the airline code and language travel as query parameters rather than a resource id in the path. You can allow the agent only to read a carrier's official check-in URL through GET /reference-data/urls/checkin-links, so it cannot reach any other Amadeus operation unless you add it. Your Amadeus client credentials stay stored and encrypted by your own instance, and the token is injected at execution time rather than exposed to the agent.
