Install Jentic One Beta

Connect the Airline Code Lookup API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Airline Code Lookup API, 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

What an agent can do with Airline Code Lookup API.

Resolve an IATA code such as BA to the carrier's commercial name

Resolve an ICAO three-letter code such as AAL to the carrier's commercial name

Look up multiple airline codes in a single GET request via the airlineCodes query parameter

For Agents

Resolve IATA or ICAO airline codes to full carrier names. Agents call /reference-data/airlines to translate codes like BA into 'British Airways' for human-readable output.

Use for: I want to translate the airline code BA to a full carrier name, Look up the airline name for IATA code AF, Find all carrier names for a list of IATA codes returned by a flight search, Get the ICAO code for British Airways

Not supported: Does not return flight schedules, fares, or availability - use for resolving IATA and ICAO airline codes to carrier names only.

Use Cases

Patterns agents use Airline Code Lookup API for, with concrete tasks.

★ Itinerary Display Enrichment

Translate IATA airline codes returned by Amadeus Flight Offers Search into the carrier's full commercial name before showing the itinerary to a traveller. The /reference-data/airlines GET endpoint accepts comma-separated codes and returns business names in a single round trip, which is faster than maintaining a static carrier table that drifts out of date.

Call /reference-data/airlines with airlineCodes=BA,AF,LH and return a map of code to carrier name.

Reporting and Reconciliation

Reports that aggregate flight bookings or fares by carrier need consistent carrier names, not ambiguous two-letter codes. The lookup API gives finance and revenue teams a single source of truth for carrier identifiers, so monthly travel reports can group spend by airline reliably even when the flight system records only the IATA code.

Resolve every distinct airline code in last month's bookings dataset to a carrier name and group spend by carrier.

Validating User-Supplied Codes

When a traveller types an airline code into a search box, validate it against the Airline Code Lookup before passing it to a downstream flight offer search. This catches typos early and gives the traveller a clearer error message than a 400 response from the flight search endpoint.

Verify that the user-supplied code XJ resolves to a known carrier and surface the carrier name back to the user.

Agent Itinerary Generation

Let an AI travel agent enrich raw flight offers with carrier names automatically. Through Jentic the agent searches for 'translate airline code to name', loads the schema, and calls the lookup with the codes pulled from a Flight Offers response. The carrier names are then woven into the natural-language itinerary the agent returns to the user.

Use Jentic to find the airline lookup operation, pass the list of codes from the flight search, and produce a natural-language itinerary with carrier names.

Why Jentic?

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

Credential isolation

Your Amadeus OAuth2 credentials are stored once, encrypted, by your own Jentic One instance and injected at execution time. They never enter the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'resolve an IATA airline code to a carrier name', and Jentic returns the matching Amadeus operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Airline Code Lookup API through Jentic.

What authentication does the Airline Code Lookup API use?

The API uses the Amadeus OAuth 2.0 client-credentials flow. Exchange your API key and secret at the Amadeus token endpoint, then send the resulting bearer token as Authorization: Bearer on the /reference-data/airlines call. Through Jentic the client credentials live in the encrypted vault and the bearer token is never exposed to the agent.

Can I look up multiple airline codes in one request?

Yes. The /reference-data/airlines endpoint accepts a comma-separated airlineCodes query parameter, so you can resolve a batch of codes returned by a flight offers search in a single round trip rather than one call per carrier.

What are the rate limits for the Airline Code Lookup API?

The OpenAPI specification does not declare rate limits. Amadeus applies a transactions-per-second cap that varies by API and contract tier - verify the exact limit for your account in the Amadeus self-service portal before relying on burst traffic.

How do I resolve an airline code through Jentic?

Run pip install jentic, then search Jentic for 'translate airline code to name'. The Airline Code Lookup operation surfaces with its input schema; pass airlineCodes=BA,AF and execute. Jentic handles the OAuth token refresh against the Amadeus auth server.

Does the Airline Code Lookup return ICAO as well as IATA codes?

Yes. Each result includes both the IATA two-letter code and the ICAO three-letter code, so a single lookup can be used to convert between the two identifiers when needed for downstream systems that expect ICAO.

Is the Airline Code Lookup API free?

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

Can I limit what my agent is allowed to do with the Airline Code Lookup API?

Yes. This API exposes a single read-only operation, GET /reference-data/airlines, which resolves IATA or ICAO codes passed as query parameters, so there is exactly one call to grant. Because Jentic One is self-hosted, you run it under your own rules and decide whether your agent may invoke that lookup at all, and the encrypted Amadeus OAuth2 credentials are injected at execution time rather than handed to the agent. Since no other operations exist on this API, scoping it comes down to allowing or withholding that one read-only lookup.
