How quickly will I receive a result?

In general, all queries are returned in 1 to 2 seconds. Sometimes an individual request can take longer (2-4s) when we have to retry submitting if it's a live search. We are monitoring the response times closely.

How many queries can I submit per second?

Our default rate limit for the Ultimate credits is 300 queries per second. This allows you to perform approximately 15,000 to 18,000 searches in 1 minute. If your specific use case requires a higher concurrency we are able to change this limit.

Are the queries made in real-time?

Yes, whenever you call our API we directly query the airlines and airports for the latest results. We do not cache anything so the returned response will reflect the latest flight data.

When are credits deducted?

Every time you receive successful responses to queries, we will deduct credits from your account balance. When your credit balance reaches zero, we will stop accepting new queries.

What payment methods do you accept?

We accept all major credit cards (Visa, Mastercard, American Express, Discover).

What is your refund policy?

We offer a full refund within 7 days of your initial credit purchase unless you have used more than 20% of your credits.

Can I request that Flystack add an API for another flight data provider?

Of course! We are always expanding our code and building new APIs for different flight data providers. You can create a feature request on our Public Roadmap at https://flystack.featurebase.app/. We aren't able to build APIs for every flight data provider for a variety of reasons but we do always make additions where they are needed and able to be done.

Do you offer technical support for users?

Yes! We are always happy to help users to be able to use our API! You can contact us through our contact page and we'll try and get back to you within a single business day.

Can I change or cancel my plan at any time?

Yes. You can upgrade, downgrade, or cancel at any time from your dashboard. Changes take effect immediately for upgrades, and at the end of the billing period for downgrades.

What happens if I run out of credits?

Once your credit balance reaches zero, new requests will be rejected until you top up your credits or upgrade to a higher plan.

Do you offer volume discounts or custom plans?

Yes. If you have high volume requirements, need a custom rate limit, or want an enterprise agreement, contact us and we'll propose a tailored plan.

Can I get invoices for my purchases?

Yes. You'll be able to access billing details and invoices from your account dashboard. If you need custom invoicing, reach out to our team.

Do you have a free plan?

Yes. You can start with a free plan to test the API and validate your integration before upgrading to a paid plan.

Is my API key secure?

Your API key should be treated like a password. Keep it server-side, never expose it in public client-side code, and rotate it if you suspect it has been leaked.

Can I increase my rate limit?

Yes. Rate limits depend on your plan. If you need higher concurrency or a custom limit, contact us and we can help you scale safely.

Do you store my requests or results?

We only keep the minimum required operational logs to run and secure the service. We do not sell your data. For specific retention or compliance requirements, contact us.

Is Flystack suitable for production use?

Yes. Flystack is built for production workloads with reliability and performance in mind. For enterprise needs (SLA, dedicated support, custom limits), contact us.

Where can I check the service status?

You can check our real-time service status on our status page. It shows uptime and any ongoing incidents.

Our API is standard REST/JSON, so you can use any HTTP client in any language. We also provide copy-paste examples in the documentation.

What should I do if a request fails?

Transient issues can happen. We recommend implementing retries with exponential backoff on your side. If you see persistent errors, contact support with request IDs and timestamps.

Can I use Flystack from the browser (frontend)?

We strongly recommend calling Flystack from your backend to keep your API key private. If you must call from the frontend, use a backend proxy and strict rate limiting.

How do I avoid getting blocked by search engines?

Flystack is designed to reduce blocks by using resilient infrastructure and smart routing. You should also follow best practices like reasonable request rates and proper error handling.

Where can I see my usage and remaining credits?

You can track usage and remaining credits in your dashboard, which helps you monitor consumption and plan upgrades.
