Every fare,
every airline, one call.
FlightAPI returns real-time prices from 700+ airlines and OTAs in a single request — plus live flight tracking, airport schedules, and IATA lookups. Pay per call. No signup, no API key juggling, no enterprise sales loop. Built for developers, travel startups, and AI agents that don't want a GDS contract.
Built for teams that need flight data without the contract.
Five concrete shapes of customer who benefit most. If you recognize your workflow, the math is in your favor.
Ship a fare-comparison app without a GDS deal.
Hit one endpoint, get fares from hundreds of airlines and OTAs back. Monetize through affiliate links or premium features without a $50k/year minimum eating your runway.
Plan trips autonomously, end-to-end.
An agent receives "find the cheapest flights from Berlin to Tokyo in June" and runs the full search loop — one-way, round-trip, multi-city — picks the best fare, and presents it. No human-managed credentials anywhere in the chain.
Scheduled price drops, zero idle cost.
A bot checks popular routes on a schedule. When a fare drops below threshold, it pushes alerts via Slack, email, or webhook. Pay-per-request pricing means days without movement cost zero.
Benchmark your fare history at API cost.
Feed your historical employee routes through the API to benchmark airline pricing across carriers and dates. Find where you overpay and when to book without paying a TMC for the same insight.
Rebook automatically when flights break.
An agent watches active flights by route. On delay or cancellation, it searches alternatives and presents rebooking options with current pricing — fast enough to matter, cheap enough to leave running.
Skip the GDS contract. Ship the search.
Open an x402 wallet, run one curl, and your first fare comparison lands in a couple of seconds. No sales call, no signup form, no monthly fee for the months you don't search. That's the entire deal.
- 700+ airlines, one call
- No signup, no API key
- MCP + x402 native
The honest answers.
If something below doesn't cover your case, ping us — we answer directly, no SDR funnel.
What flight data does the API return?
+
Real-time pricing for one-way, round-trip, and multi-city flights from 700+ airlines and OTAs. Plus live flight tracking, airport departure/arrival schedules, airline details, and IATA code lookups — all under the same per-call billing.
Do I need to sign up or get an API key?
+
No. The API works through x402 per-request authentication. No account creation, no API key to rotate, no sales call. Connect a wallet, sign the request, get fares back.
How current is the pricing data?
+
Prices are fetched in real time from airline and OTA sources. Each API call returns live market rates at the moment of the request — not an indexed snapshot, not a six-hour-old cache.
Can AI agents use this without human setup?
+
Yes. The endpoint supports MCP discovery (Claude, Cursor, Windsurf) and x402 micropayments. An autonomous agent can find the endpoint, call it, and pay — no human-managed credentials in the loop.
How does pricing compare to Amadeus or AviationStack?
+
Amadeus requires enterprise contracts and significant onboarding. AviationStack runs on monthly subscription tiers. FlightAPI charges per request with no signup, no monthly minimum, and native MCP support — better math for variable usage and for agents that run sporadically.
Are bookings supported?
+
Not directly through this endpoint — it's read-only flight data (prices, status, schedules). Booking is a different shape of integration with each carrier; this API gives you the inputs, your booking flow makes the action.
