# Version disclaimer

SwapKit's latest version is v3, it is the recommended version to integrate. The documentation for v2 is currently shared here until support for it is discontinnued to help current v2 integrations in their process to upgrade or mantain their integration if they have issues.

### How to use SwapKit's API v2

To get the most out of SwapKit's API v2 we recommend going through the endpoints in the following order:

1. **`/providers`** – Retrieve a list of available providers and their supported chains.
2. **`/tokens`** – Fetch a list of supported tokens across different chains and providers.
3. **`/quote`** – Request a swap quote to estimate the cost and parameters for a transaction.
4. **`/track`** – Track the status of a swap to monitor its progress and completion.

However, `/providers` and `/tokens` don't change often, and you can directly request a quote once you have everything set up.\
Additionally, the `/screen` endpoint can be used to validate AML compliance of the involved addresses. If it is something you need, use it before the transaction is offered for signing and not with every `/quote`.\
You can try the API yourself at <https://api.swapkit.dev/docs/> . \
You can also check out our transaction tracking interface at <https://track.swapkit.dev/>.\
Please read over our recommended [quote implementation flow](/swapkit-api/quote-and-swap-implementation-flow.md) to understand how to create a better performing integration.
